materials and concept for an old style GUIDE TO SELECT NG YOUR STEERING SYSTEM
Not too long ago wheel steering was only associated with large ocean racing and traditional sailboats The rapidly growing trend towards wheel steering
has changed to include cruising and racing sailboats as small as 18 feet Many people once believed the only way toget theUfeelof a sailboat was with a
tillerThe popularity of wheel steering as well as its practicality has shown even the most adamant tiller man that better feel and better boat control
can be obtained with wheel steering Without the tiller sweeping theentire cockpit the crew can perform more functionally guests can relax more
comfortably and shorthanded family sailing suddenly becomes simple Planning a steering system for a tiller conversion or an option on a new boat is
not a casual matter and should be done with the utmost thought and More time should go into the planning of acockpit than any other part of the boat
this is where the crew spends the vast majority of their time whether the boat is for cruising or racing Moreover the cockpit is the base for handling
sails as well as steering Thus in this one area of the boat comfort convenience performance and safety are all equally vital factors neglect even one
and the pleasure of sailing is in ieooardv
A major part of planning agood steering installation islocating thesteerer This must take location of the rudderpost winches main sheet and engine
controls All must be located properly or moved to the appropriate location for a functional and comfortable cockpit The aft cockpit steering location
is normally associated with h t e older traditional design where a worm gear type steerer to a rudderpost located in the aft end of the cock O p i t
It is also the location used for the New Edson Rack and Pinion Steerer installed abovedeck directly toarudderpost located in thevery aft end of the
cockpit or with atransom hung rudder The is often locatedwell aft in thecockpit in cruising and racing boats minimum distance 21 inches from the
pedestal centerline to the aft cockpit bulkhead any of theseaft steering installations is that the helmsman is well aft out of theway of crew members
working winches From this position the helmsman sees all the action can cast off sheets or tail winches participate in cockpit conversation and has a
complete view of the sails and rig In the midcockpit installation the helm is farther forward where the boat is wider so the helmsman can get more
outboard instruments mounted in the cabin bulkhead can beeasily read the winches and cleats are more accessible to the helmsman whether they are
forward or aft of the helm On a cruising boat this location clears the aft end of thecockpit forcrew members or guests not needed for handling sheets
Neither the backstay nor main sheet need interfere with the helmsman standing behind the wheel and the helmsman has sufficient room to brace his feet
without restriction With the helm in midcockpit winch location does become critical especially when installing wheel steer in in an exist in c o c k
iwhere t winch locations are fixed concentrating both winches and helm in the middle of the cockpit can be most inconvenient for both helmsman and
crew The forward cockpit installation places the helmsman close to the companionway under the protection of a dodger out of the way of winches and
main sheet and in a wide part of the boat where head sails can be easily viewed fihoing the type of steerer is specifically covered on its I of this
catalog however each has certain which are best suited for a particular type boat Rack and Pinion Steering is most useful on boats from 16 to 40 feet
where space under the cockpit floor is limited or for those small sailboats with transom hung rudders such as the trailerable models The inboard
rudder models that are particularly well suited are those with the rudderpost coming through the aft

the very aft part of the cockpit floor The Rack and Pinion can virtually be plugged into these setups with a minimumamount of installation effort with
the exception of building a cover over the steerer to serve as a helm seat Worm Gear Steering is often referred to as meaning the feedback from the
rudder will not normally turn the wheel when the helmsman lets go of the wheel These steerers are most often used on traditional boats with aft raked
inboard rudders Because of the rake it is often impossible t o install a quadrant underthe cockpit floor This type of steerer is attached directly to
the rudderpost above the cockpit floor at right angles to the rudderpost The steerer shaft may be fitted with a universal and an extra bearing to
build in the exact wheel helm A wheel box must be built overthe steerer to serve as a helm seat This box can be kept as narrow as possibleso the
helmsman can sit behindoralong side the wheel The box can have a flip up top to serve as a seat back for long watches at the wheel Engine controls can
be located right on the sideof the helm seat within easy reach of the helmsman Despite the worm gear steerer being there are always those boats with
an excetional weather helm or oarticularlv hard steering For these boats we now offera fridtion shaft brak for all sizes of worm steerers Bulkhead
Steerers are most advantageous for power boats motorsailers two station steering MidShip Cockpit boats and bridge deck console type steering stations
generally found on custom racing boats Bulkhead steerers can be purchased for very small boats using direct sprocket and chain drive as well as 2l and
3l geared reduction sprocket and chain steerers for very large commercial vessels such as fishing boats and tug boats Pedestal Steering is well suited
for both midship cockpit and aft cockpit boats with inboard rudders as well as transom hung rudders This system requires space under the cockpit floor
for mounting sheaves sheave bracket or Radial drive Steering System It offers maximum flexibility in that any number of sheaves may be mounted to
route wire rope around engine spaces through aft cabins or around fuel tanks etcThe pedestal type system comprised of sprocket chain and wire rope can
be used very efficiently for both cruising and racing boats up to 80 feet by varying the size of the steering wheel and the size of the quadrant
toeffectively changethe poweroutput necessaryto sail your boat This steerer is very popular and most versatile when planning your cockpit for
convenience accessories such as brake guard tables instrument housings engine controls helm seat and autopilot drives PullPull Steering is a new
system offered by Edson as an alternative to a sheave and wire rope system This System can be used with either Bulkhead or Pedestal Steerers with
inboard or outboard rudder boats It is most advantageous for MidShip Cockpit and Aft Cabin boats when routing the steering cables from the Center
Cockpit to the rudderpost can become complicated The PullPull System uses standard Edson components in conjunction with flexible conduit housing 7 x
19 stainless steel wire rope Unlike pushpull cables such as those used on engine controls pullpull is always in tension The result is very positive
steering control without the play and lost motion generally associated with a PushPull Cable Each steering section of the catalog shows a chart for
selecting the recommended size steering system for your boat Each chart is composed of information gathered from our many years of leadership in
marine steering Due to the many variations in yacht design in areas of hull shape engine horsepower and sail final must be approved by your Naval

should be carefully and for transom hung rudder inboard rudder double ended boats with dl board rudder racing and cruising boats to about 40 feet
these steerers offer the answer for those requiring a compact powerful and sensitive wheel system for their craft Positive response provides the
helmsman with complete feel of the rudderThe transom hung models offer 16 turns of the wheel lock to lock in 70 and the inboard models 18 turns to
lock in 80 Easeof installation is primary hung rudder models attach directly to the rudder through a slot approximately 2 x 6 in the transom lnboard
rudder models attach to the rudderpost or rudderpost extension and are available for mounting either fore or aft of the steerer frames then bolt onto

to the aft face of the wheel hub If you intend on buildina a helm seat over the steerer be sure to add 6 to 8 inches for ieg clearance between the
forward edge of the seat and the wheel If there is any question make the shaft a little long as it can be made shorter on the job 2 The width of the
rudder or rudderstock dictates the size for transom hung rudder steerers Fig 341 and Fig 342 If in doubt get the next wider jaws as you can always
shim the sides of the casting The jaws on the gear rack are drilled at the time of installation 3 The rudder post diameter determines the size of rack

height and angle of the wheel shaft are correct Securely bolt the housing in place on the aft deck or mounting platform Make sure this surface has
suffi ient strength as it must absorb all of the steering loads If required tlJ einforce it Stops such as wooden blocks shown to the right should now
be installed on both sides of the steerer to limit its travel to the desired arc The box over the steerer should be waterproof yet readily removable
If you intend this box to double as a helmsman seat be sure to build it high enough to allow good visibility over the cabin top Provisions for
emergency steering should be made by fitting a removable tiller on top of the rudder post

The Rack Aft steerers are for those boats with at least 12 inches of space aft of the rudderpost and limited space forward The basic dimension of the
gear should be carefully noted as it is important to place the wheel about 32 inches up from the cockpit sole to allow the helmsman to steer
specifically for double ended boats up to about 38 with transom hung rudders Edsons new model Rack and Pinion Steerer operates in a similar fashion to
the standard Rack and Pinion Steerer with the feel of a tiller and very responsive to the touch It is available in two models for straight inline
installations on vertical or nearly verticle rudders and for offset requiring a shaft universal and an adjustable bearing for angled rudders They
require only a small slot in the stern for the operating rod This slot can be easily sealed with a homemade boot similar to one for a mast step Fig814

severly aft raked rudderposts This steerer comes with ashaft universal and two 1self aligning bearingsThis steerer allows the adjustment of the angle
of the steering wheel within a 30 23 575 cm or to of all it is important to establish and install the reinforced platform that the dummy
rudderpost is going to be bolted to Bear in mind that this surface must be of sufficient strength as it must absorb all of the steering loads This
platform must be 90 to the rudder on a plane where you wish to install the rudder lever Also note that the geared rack and pinion quadrant requires a
minimum of 10 on each side of the dummy rudderpost to swing in This dimension will help in establishing the C dimensions Temporarily mount the dummy
rudderpost and assemble the rack and pinion gear and housing Assemble the clevis the connecting rod and the rudder lever unit With C clamps attach the
rudder lever unit to the rudder Now operate the steerer noting the rudder travel from side to side The location of the lever on the rudder either fore
or aft or possibly even shimmed to starboard determines equal travel from side to side Take time with the positioning of this lever and be precise
When you are satisfied secure all parts and install stops such as wooden blocks on each side of steerer to limit its travel to the desired arc
Provisions for an emergency tiller should now be made if you do not already have one

The New Fig 345 Aft Mount Rack and Pinion Steerers are for use on boats with rudderposts raking forward Although similar to Fig 344 in function the
exact location of the shaft universal allows adjustment of the steering wheel from a position parallel to the plane of the rudderpost to a more
comfortable vertical or aft rake position MAINTENANCE Maintenance of Rack Pinion Steerers is minimal and when performed at least oncea month will

dampening action is especially handy on long runs or when operating under power Can also be used to hold the boat on course under most conditions As a
safety feature the brake can be overridden by the helmsman The Brake mounts on the wheel shaft against the inside forward wall of the wheel box with
the adjusting knob coming out either side of the box Brakes are constructed Fig 345 Aft Mounted Rack a Pinion Steerer is ideal for installations

for all available sizes see p r i s pages
Worm steerer installations must be well designed and well thought out from all standpoints The basic system is mounted at 90 to the rudderpost and is
rigid at this point The SelfAligning Bearing supplied with the gear must be well bolted down to a timber or strong moldment on a fiberglass design It
is important to design in the basic features that make for a successful installation It is recommended that the top of the wheel the actual part you
hold onto be 31 79cm to 33182cm up from the cockpit floor This will allow standing beside the wheel without reaching down to the wheel also sitting in
back of the wheel or alongside it and have the wheel at a convenient height Essentially a Worm Steerer is a nonreversing system with little to no feel
and is most commonly used on a longkeeled cruising design The steerer design features more turns pf the wheel from hard over to hard over than is
normally designed into a wire type of pedestal systems The Worm Steerers would then not be recommended for a shortkeeled fast turning boat or one that
does not track as well as the longkeeled boats The nonreversing feature will hold the wheel in place on most boats most of the time It will give or
turn if the boat is hit by a large wave or the boat has an excessive helm due to basic design force of the wind or balance of the sails The gears are
strong and relatively heavy as they must stand all of the strain of the rudder when transmitted to the gear The shaft extension or the wheel shaft
itself can be easily 9pated to an AutoPilot by the addition of the necessary Jilot sprocket The choice of the location is one that will allow the
sprocket chain to be led at right angles to the worm shaft directly to the AutoPilot motor box When ordering advise Edson of Rudderpost bore diameter
Keyway size and Keyway position these will be machined by Edson If a special A length is required be sure to include it

For excessively raked rudderposts Edson offers a Simplex with the Shaft Universal Assembly on the wheel shaft and an exfra SelfAligning Bearing for
the needed forward wheel shaft support This combination can reducethe wheel angle by a maximum of 30 up or down That is if the rudderpost is at 45 to
the waterline the wheel can be angled at only 15 Edson feels the maximum angleof the wheel should be no more than 20 Likewise on near vertical
rudderposts the same setup can be used to give the wheel some aft rake This angle is important as it will give the helmsman room for his knees while
the top of the wheel is closer to his arms If in doubt as to steerer size or if the boat is very heavygo larger Do Not compromise the final size For
those boats where the rudderpost ends at the cockpit floor level Edson can furnish the Fig 675 Coupling and aFig 782 Rudderpost Extender of the

dscn SELECTING A PEDESTAL STEERING SYSTEM
Edson now offers many types of pedestal steering systems specifically designed for maximum performance and Edson reliability as well as ease of
installation Each system is predrilledto accept any of the convenient addon accessories at any time Carefully review each type shown in the following
pages as well as the Edson dataSheet for your particular boat Edson has over 1200 installation drawings which we call If you own a stock boat feel
free to request a DataSheet on that boat or if you are building or purchasing acustom boat send us in aconstruction drawing or good sketch and we will
gladly send a complete proposal and DataSheet representing a similar installation may vary in wheel size sheave size chain d l e n g t h and
quadrant size depending on the size and displacement of the boat and the type of sailing being done For cruising and offshore work a larger quadrant
with more power output and more turns of the wheel hard over to hard over is preferable For racing a smaller quadrant with fewer number of turns and a
larger wheel will provide faster action especially useful for downwind sailing For THE PEDSTAL STEERING SYSTEM
d s s a n
sizes see the table below Edson will also supply upon request Data Sheets and specific covering the best system for your boat For boats being able to
use more than one system will be given in order of preference For specific information for converting or planning your boat send us your construction
drawings andlor sales literature along with the type of steering system you wish to install

Heavy u a d r a nSystem t is best used where the rudder post has considerable rake forward or aft or where tanks cockpit drains exhaust lines or
other obstuctions require routing of the wire rope through two or more sheaves This uses wood supports to tie the cockpit to the hull keeping steering
loads from wracking the cockpit This system has been used for many years and is excellent for conversion of tiller boats as well as new Sheave
Bracket System is ideal for installation on stock boats as well as by owners or yards It is excellent for those boats having the cockpit seat risers
along side the radius of the quadrant where wooden blocks can be glassed in on the sail locker side of the seat risers flush with the bottom of the
cockpit floor This unit has a built in quadrant stop and fully adjustable sheaves Radial Drive Steering System is ideal for sail or power boats up to
40 feet with vertical or nearly vertical aluminum or stainless steel rudderposts whe7e cables can be led directly onto the drive wheel The Radial
Drive can also be used on boats larger than 40 when using an independent rudderpost stop On boats over 40 feet Edson would like complete blueprints
and requires the final approval of your naval architect This system is designed to be simple and economical with fewer moving parts Feel and
performance is equal to other Edson steerers It can be used equally as well with pedestal or bylkhead steerers on any boat with adequate clearance
around the rudderpost It can also be used in conjunction with the PullPull conduit on midship cockpit designs or on boats with a variety of

2 with Radial Drive For sailboats with an aft cabin this is a natural The Pedestal installation uses a Fig 841 dropped conduit mounting plate for
attaching the conduit at the pedestal The conduit is routed along the starboard side under a bunk to the Radial Drive Bracket is often found where a
bunk or lazarette might interfere with a Radial Drive or Sheaves When a bunk is located under the cockpit use the Edson Fig 825 mounting platform
shown in the PullPull section of this catalog This installation keeps the conduit neatly up against the underside of the cockpit floor This can only
be used with 65 or 8 Radial Drive or 8 quadrant dueto chain travel limitations Hydraulic Steering Adapter Kits Edson Steering Adapter Kits permit any
of the Edson Pedestal Steerers to be e a s y l i installed in conjunction with Hydraulic Steering Systems The below cockpit illustrations show the

information see inside f r o n t cover
The value of this chart is twofold One to get steerer output secondly to get a working relationship between steerer output and equivalent tiller
length To obtain the equivalent tiller length divide the output figure by 40 For example a boat with a 24 wheel and a 12 quadrant has an output of 432
ft Ibs Divided by 40 this equals the leverage of an 11 foot tiller Second it is interesting to note that a 30 wheel with an 8 quadrant has the
identical output of a 20 wheel with a 12 quadrant the difference being the number of turns The first with 18 turns has fast action and a large wheel
the preference of most racing skippers The second with 27 turns has a sloweraction and a smaller wheel for the boat used primarily for cruising Which
do you prefer We can fit the steering action to your STEERERS
All Edson pedestals are designed for versatile installation in virtually all types and sizes of boats A well designed and well installed pedestal with
its greater mechanical advantage gives better boat handling with more feel than a tiller and far more usable cockpit space A pedestal enables the
entire family to handle the boat under virtually all conditions Edson offers 4 basic pedestals The Fig 334 is usually used on smaller boats and
includes a molded compass adapter for smaller 3 4 or 5 flush mount compasses The Fig 335 is the same basic pedestal as the Fig 334 only it comes
without the molded compass adapter and it will accept most all standard 5 compasses The Fig 400s and 420s Deluxe Pedestals for larger boats will
accept most all 6 compasses and come equipped with extra needle bearings and liners and the pedestal brake is standard When choosing a pedestal
remember all pedestals look somewhat alike on the outside yet the inner workings are most important For instance the 334 pedestal comes with the same
8 roller chain used in our larger pedestals Edson does not believe in compromising by going lighter for a smaller boat as the loads can become high
under storm conditions All edestals are predrilled to accept all accessories shown in the catalog with a minimum amount of installation time Please
note compasses are not included with the pedestal for compass selection see Fig 658 in this stainless steel needle bearings Ilke the ftnest winches

sheaves are especially designed for use in wire rope steering systems All sheave housings are rigidly constructed of solid bronze stainless steel or
aluminum and are designed to Drevent the wire from i u m i n a out of the sheave Scores are machined extra deep and are concentrk with the bearings
to maintain constant wire tension The bearings for all bronze sheaves are oil impregnated bronze bearings aluminum sheaves feature precise stainless
steel needle bearings Sheave hubs are wider than the rims to prevent side friction and noise All sheaves have to simplify installation or wire
replacement In addition all sheave housings have pin arrestor systems designed to prevent premature sheave pin wear The new Fig 620 and 743 Thinking
Mans Sheave Housings are another Edson original The Fig 6204 has a stainless steel housing for even greater strength and reliability This is excellent
for use on boats of
aluminum construction to eliminate the possibility of electrolysis 620 is supplied as standard equipment in all Edson steering systems for production
boats Edsons Fig 743 is the latest answer for bulkhead mounting Both sheave housings have elongated bolt hole slots for aligning the wire lead along
with two additional bolt holes for securely locking that setting The Fig 621 Flat Sheave is ideal for mounting on power boats or under cockpit floors
on sailboats The Fig 623 Double Upright Sheave Assembly is commonly used on midship cockpit designs on inside steering stations where both wires lead
aft on the same side of the boat In order to ensure a long life and proper operation of your Edson sheaves proper maintainance is essential Sheave
bearings should be oiled monthly failure to do so will result in premature wear and the possible seizinq of the Chain and Wire Rope with all

Manganese Bronze or 356lT6 Heat Treated Aluminum alloy To simplify installation all quadrants quickly adapt to the exclusive Fig 618 Edson Wire Takeup
Eyes All quadrants will accept wire rope up to 3181952 cm in diameter The various quadrants listed below are shown by rudder post or bore size and are
available in different models including Space Saving Offset standard straight Double Offset and Dual Ratio Quadrants When ordering please supply an
accurate dimension of your rudder post or the desired bore along with the key size and Edson will machine the quadrant to suit Edson allows a 5 to 6
thousandth clamping action of the cap to the rudderpost The quadrant must be carefully fitted for optimum strength if it is fitted too tightly the cap
could try to bend when tightened and if fitted too loosely the quadrant could work or drop Both the above could cause premature failure Solid stock
rudderposts are normally keyed and hollow pipe stock rudderposts are normally pinned Edson will provide the pin with the predrilled cap Edson sees a
trend toward machined keyways in hollow rudderposts as they allow for easy adjustment up and down the rudderpost Most keyways are 114 square so they
do not penetrate the wall thickness

One Edson specialty is a combination Rudderpost Bearing and above the waterline stuffing box Edson offers two types of stuffing boxes starting with
type B for the most common used rudder shafts measuring 1 through 3 in diameter Type B Stuffing Boxes are designed to be either fiberglassed in place
or fastened to the rudderpost tubing with hose and hose clamps Type C for the less frequently used and larger size rudder shafts through 3112 must be
glassed in place Edson recommends fiberglassing the stuffing box bearing to the top of the tubing when the rudderpost is in place This makes the post
a structural bearing and will carry the rudder loads with minimal friction The hose coupling method can be used however when under a load the stuffing
box is apt to bend and add friction to the steerina svstem When used with hoses the following sizes can be used 2 2IT 3 and 3112 See the price page

PEDESTAL AROUND FRICTION BRAKE FOR PEDESTAL STEERERS
The most popular accessory for all steerers Brakes are designed to dampen the action of the wheel especially handy on long runs orwhen operating under
power Can also be used to hold the boat on course under most conditions while the helmsman trims that sheet or goes below As a safety feature the
brake can always be overridden by the helmsman All mounting holes in the steerers are predrilled at the factory allowing simple installation in about
15 minutes Brakes are constructed of bronze with long lasting brake lining and supplied with stainless steel shaft and shiny black brake handle The
handle is designed to pop if a line gets tangled an added safety feature When the boat is unattended secure the wheel with the brake In rough weather
the rudder can swing violently from stop to stop causing damage Note If you do not own a wheel brake you must tie off your wheel at no time should
your wheel be allowed t o swing free as it could damage your steering system

I With the ever increasina number of sophisticated instrcl Qx ments on the market today the question of the location of these instruments has become
of prime importance to the boat owner The latest trend of mounting the instruments on the steering pedestal has several distinct advantages It
provides for a neat andefficient steering area the helmsman has an unobstructed view of the instruments the instruments become more serviceable and of
course it no longer becomes necessary to drill and cut into the boats deck house Edson has now designed housings and pods for one two three or four
Pedestal lnstrument Displays All are designed with the Edson Pedestal Guard which not only protects the crew and the instruments but in turn permits
the owner to have a table and other pedestal accessories These Guards are positioned 4 forward of the pedestals to allow the top housing or pod to be

reinforcing that is normally located below the aft bunk This type conduit can run through a sail locker or in a hanging locker as the wire is totally
encased and there is no chance of the moving wire catching or jamming Being conservative we have limited the PullPull to boats 42 foot or less as we
feel that long lengths of conduit would reduce the sensitivity of the steering However small sections of PullPull conduit can be used on any size boat
In our continuing program of development these systems have been installed on several 48 foot motorsailors with excellent results The next drawing
shows a very popular method of running the conduit that of straight down the center of the boat and then up to two of the new idlersand then into
thequadrant As can be readily seen there are two lengths of conduit that carry the steering cables from the pedestal down and aft past the engine and
they are terminated at a strong bulkhead alongside the propellor shaft There are then free lengths of wire that go aft to an area just forward of the
rudderpost and the conduit is again used This aft conduit need normally only be 3 or 4 feetin length and would lead the steering wires up and out to
two idlers and then 90 degrees into the quadrant With two seperate conduits per side the cost is reduced the friction of excessive length is reduced
and maintenance is made much easier Also shown is a very popular 36 foot Pilot House Sloop using a combination of sheaves and conduit to give a good
The forward steering station uses an Edson Figure 338 Bulkhead Steerer going down to a Figure 625 Idler and then aft Part way back two 8 foot lengths
of conduit allow the wire to go up one and down the other side of a tank this run eliminates eight sheaves at this point The aft steering station
incorporates a Pedestal or following four pages cover the latest addition to the Edson Family the PullPull steering systems These systems are
adaptable to power boats midship and aft cockpit sailing craft Basically thesystem is used in conjunction with apedestal or bulkhead steerer and
theconduit takes the placeof of the installation makes this method of steering very appealing The PullPull conduit is made with an inner core of
polyethylene which is covered by many strands of steel wire These wires are then wrapped with aflat wireand is then sealed by a plastic cover The
steel wrapping gives the conduit that extra strength and is exclusively an Edson featureThe conduit comes to Edson from the aircraft industry and has
been successfully tested to 600000 cycles without failure The Edson Figure 827 Lubricant which is used in maintaining the PullPull system is an inert
base oil combined with Teflon and is an important addition as it reduces friction bv about 30 oercent
The easiest of all methods is that shown here that of takina a bulkhead steerer on either power or sailboat and run it out around
The conduit can snakearound neatly through a cabin area or over and around a tank line In effect we recommend PullPull where straight line sheave to
sheave wheel cable systems are difficult to fit We find that on many pilot house boats with dual steering stations that the aft steerer will be all
sheaves but the forward station will use a combination of sheaves and PullPull conduit The conduit will be used fora length of 8 to 10 feet as it
snakes down the interiorwhile going upand over and down an obstacle and then into a Radial Drive or other sheave
SAILBOAT the following pages we are showing the various methods of installing the conduits as well as the different specialized hardware designed by
Edson to make the installation easierand also to allow for easier maintenance and inspection of the completed system As in all steering systems the
basic setup should be made to use as many of the existing structural members as is reasonably possible If a bulkheadcan belocated to serve as an
anchoring point for the conduit or one of the new conduit sheave assemblies so much theeasier Needless tosay the bulkheads must bestrong and up to the
steering loads that will be put upon them The aft plywood gussetts mustbe adequately reinforced to accept theend fittings of the conduit An easy way
to locate theend fitting is by placing a inch dowel or rod in the groove of the quadrant and at 90 degrees to the centerline go to the gussett which
is fore and aft and drill a la inch hole for the conduit end fitting see With the dowel in the other groove of the quadrant drill the opposite
gussett for the opposing PullPull conduit
easily adapts for use with outboard rudder boats as shown cables run beneath the sail locker on one side and under a quarterberth on the other
PullPull is shown here in a particularly complicated aftcockpit arrangement This illustration shows the PullPull conduit being run between quarter
berths and around a tank where wire rope and sheaves would be very difficult to PullPull systems easily adapt to include automatic steering The
sketch above shows the autopilot placed under a berth and connected to a separate quadrant On the pilot house 36 to the left the auto pilot operates
off the bulkhead steerer The two sketches at the left show additional methods of running
If there are no gussetts opposite the quadrant radius the Figure 82417 Bracket can be used as it can be bolted to a flat surface either parallel to
the top of thestop pointeddown or on a flat parallel surface directly under the quadrant This bracket must be carefully located and well bolted down
as the stop pin must hold the expected rudder loads in the hardover position For complete warranty information see inside f r o n t A garden hose
marked in 1 increments can be used to simulate your conduit when planning out your system EXTRA STEERING STEERING f Edson has designed a
number of special fittings for use with the PullPull systems For ease of selection we have noted the conduit itself and then divided up the fittings
as to Wheel End and Rudder Post End of the systemThe conduit and wire rope can be easily cut so estimate a little extra length when ordering As shown

AUTOPILOT STEERING SYSTEMS
When planning your steering system it is best to think ahead AutoPilots are more popular than ever and easier to install Edson nas developed three
basic methods of attaching autopilots first all Edson Bulkhead Steerers Rack and Pinion and Worm Steerers can have autopilots attached directly to
the wheel shaft extension or the wheel shaft itself nothing extra to purchase Second the use of the Edson Figure 320 AutoPilot Drive with the
addition of one or two sheaves and the appropriate roller chain can adapt virtually all Edson Pedestal Systems to AutoPilot attachment With the 320
the boat can use an extra quadrant or radial drive for a completely separate system or can introduce the 320 in to the basic wire system Third the
all new Edson Rapid Drive for a right angle gear box drive the simplest system for owner yard and boat builder As a general guide the simpler the
system the better On any installation involving electricity the area must be well proteted from moisture and the wires used must be of the correct
size and used with good solid terminal ends At no time can the unit be exposed to salt water such as would occur if the electrical panel was placed
below a sail locker As obvious as this may sound we still see many units so mounted The compass unit must be kept away from the boats navigation
compass as well as from other interferences such as an alternator on an engine Take the Fig 320 Pedestal System first There are two basic concepts
that can be used in the installation of an automatic oilot with a oedestal One is to place the Fig 320utopilot Drive Unit withinthe boats existing
steering system This would be as in illustrations 1 and 2 A second method would be to use a second auadrant or radial drive that would in effect make
an independent system here is a great deal of merit to this latter approach as any boat would then have three methods of steering There would be the
egular boats steering system the automatic pilot driven by electricity and the emergency tiller The extra quadrant or radial drive would eliminate
having to cut into the boats system and is generally the preferred method for conversion to an autopilot As can be seen in Figs 3 and 4 the extra
quadrant or radial drive can be placed above or below the regular steering systems quadrant or radial drive and in the case of the quadrant on either
the forward or aft side or for that matter on a fore and aft plane The ultimate choice is determined by where you have room for the actual pilot

shaft extension When ordering your AutoPilot please note that the shaft for the sprocket is 1 with a lh keyway Maximum Input Rating of the Rapid Drive
is 1000 inch pounds based on a 41 ten tooth power unit sprocket One of the variations of the unit is the Fig 319 Rapid Drive which incorporates the
universal and an extra selfaligning bearing This unit allows either the basic Rapid Drive to be mounted other than fore or aft and to angle the shaft
extension to facilitate locating the actual AutoPilot The illustrations below show some of the many variations available when using Rapid Drive
ORDERING INSTRUCTIONS Rapid is available in 6 sizes for rudderposts of various sizes When ordering it is necessary to specify the rudderpost bore

furnish the pilot manufacturer the number of turns hard over to hard over in 90 in your steering system so they can recommend the proper size drive
sprocket The number of turns and length of roller chain for a given size quadrant or Radial Drive is shown in the selection chart for each type
steerer In the case of conversion to a pilot h i t h a pedestal it is necessary to purchase the following items 1 Fig 320Size 2 Auto Pilot Drive Unit
2 an appropriate length of 5 Roller Chain Fig 630s The length is determined by the quadrant or Radial Drive size to which the pilot is to be
attached This should be accompanied by the necessary wire rope roller chain master links end fittings and the necessary extra sheave or sheaves to
accomplish the installation Be sure to use the same size sheaves as are in the regular steering system for the Rapid Drive and the AutoPilot must be
securely held to a platform The electrical wirGg to the AutoPilot must be of the size recommended by the AutoPilot maker and fastened with good solid
terminals The installation must be protected from moisture As in all exposed gearing the Rapid must be covered by a clear Lexan or equivalent cover to
keep equipment and fingers out of the mechanism The clear cover permits ready visual inspection Maintenance of the Rapid is simple use 30 or equal
Motor oil on the shaft bearings and on the geared segments and wipe across the bottom of the segment Water pump grease can also be smeared on at this
point The unit should be inspected like all steering equipment and it is wise to checkand oil it at least once a AND INSTALLATION GUIDE
AFT COCKPIT STEERING
pI AND INSTALWTBON This Aft Cockpit planning guide has been written to assist the boat owner boatyard and the designer in making the most convenient
pedestal installation for any given cockpit design Before making a final decision on the location of the steerer it is always a good idea to make a
dummy steerer out of a 2 x 4 a short length of broomstick handle for the shaft and a cardboard or plywood cutout of the chosen wheel size At the same
time the area below the cockpit floor should be checked for obstructions such as tanks lines etc and also to check to see if the builder installed
cockpit floor reinforcing and its exact location The location of the winches and the helmsmans visibility should also be noted
AFT COCKPIT STEERING 6 shows the rudder post forward and the steerer aft Note that the wires can run forward or aft to the quadrant If the steerer is
placed up against the rudder post the forward side of the base can be Milled off to gain space With the helmsman aft all of the crew is forward and
they must handle the sailing of the boat as the helmsman can not contribute any reasonable assistance This is usually no problem on a 45 footer that
requires a larger crew but on a 35 footer or less i t can present problems However when cruising this can be an advantage since the skipper can
supervise sail handling and keep track of children and 2 shows a forward steerer installation using Edsons quadrant and sheaves Note how the Clutch
and Throttle Control is safely nested between the wheel and guard This prevents snagging lines or accidental shifting while keeping controls close at
hand the helmsman does not have to look away during that important tra tion 4 shows pedestal in mid cockpit using PullPull shown in a particularly
complicated arrangement This illustration shows the PullPull conduit being run between quarter berths and around a tank where wire rope and sheaves
would be very difficult to OUTBOARD RUDDER 1 Forward 1 shows a steerer forward using Radial Drive By plating the steererat the forward end of the
cockpit the helmsman has the protection of the companionway dodger and has quick and easy access to the cabin below The forward location also keeps
the cockpit activity aft of the helm and when in shorthanded situations allows the helmsman to steer and handle the sheets with the minimum of
difficulty Edson suggests using a large size wheel within 2 or 3 of the cockpit seats if the boat has a bridge deck as there will be no need for
guests or crew to slide by the wheel We also recommend the installation of a pedestal guard as a handhold for crew members going below The larger
wheel will allow the helmsman to comfortably lean against the coaming and to have excellent allaround visibility In many conversions from tiller to
wheel the forward locations makes for the least cockpit layout change as i t places the helmsman in approximately the same location with the wheel as
with the tiller For a racing boat all the action is aft and when not tacking the crew can sit to weather and forward if it improves the balance of the
easily adapts for use with outboard rudder boats As shown above cables run beneath the sail locker on one side and under a quarterberth on the other
lllustration 3 shows a pedestal steering installation on an average 25 to 30 footer with transom hung rudder The Edson Fig 612 1 I Quadrant series
can be used on most all boats of this design The quadrant should be mounted fairly high on the rudder to fit within the lazarette or so a box or
helmsmans seat can be built over it as illustrated As a rough guide to the following Fig 612 Quadrant sizes should be used Boat Length 20 to 36
feeff611 m I 0 inch size126 cm 37 to 45 feeff1214m 14 inch size136 cm 45 to 60 feeU1418 m 20 inch size150 cm The above chart must be used
with caution obviously a very hardtosteer boat must go to the next size larger quadrant than is indicated With all Edson Pedestals the quadrant size
in inches is roughly equal to tiller length in feet As in any opening in the transom it must be booted or a drain pan or area must be installed to
prevent water from getting into the structure of the boat As a further guide the 10 quadrant requires a transom hole of about 25 cm by 615 7
In lllustration 7 the rudder post is vertical and there is a quarter berth on the port side aft The solution was to mount the quadrant angled to one
side and to lead one of the wires directly into the quadrant and the other aft to a sheave and back into the quadrant As a matter of interest one of
the earlier boats on which this was done was a 36 footer The idler sheaves were 410 cm as the wire only went around the idler sheaves 90 degrees On
the aft single sheave i t was 615cm as the wire goes around it about 180 degrees the larger sheave will increase the feel of the rudder from reduced
wire friction GENERAL As in all Edson tries to reduce the number of sheaves They must be bought installed and each one adds its friction effect A
good needle bearing pedestal with as few sheaves as possible with well oiled bushings and a well hung rudder will give a very sensitive system and one
that is free of problems The T Cockpit can have the steerer placed aft pictured so the helmsman is sitting on the aft seat and sliding around to the
sides or another variation would place the pedestal well forward in the cockpit and bring the primary winches aft by the base of the T so the winch
grinders can stand by the handles Likewise downwind under a spinnaker i t would give the sheet handlers more room and hopefully less chance of error
One distinct advantage of the aft steerer arrangement is that the helmsman can see all that is going on in the cockpit an important factor when racing
When the steerer is placed at the extreme aft end of the boat be sure that the jib luff can be easily seen and i t not being visually blocked by the

The aft location of the wheel in a long narrow cockpit is the traditional location of a pedestal The helmsman can see all of the action and if a line
jams or some other problem develos he can take the best corrective action if the steerer is well aft itis a good idea to put on the narrow
pedestalguard and for the engine controls to be placed on the steerer When planning this installation beware of such potential problems as a tall
helmsmans head hitting the backstay or the possibility of the main sheet catching the pedestal also be certain you have enough space at least 16141 cm
clearance behind the wheel to allow foot room at the helm At Edson we can always tell when a pedestal is too far aft there are heel marks on the end
of the cockpit where the helmsman has tried to move his feet aft and found no space lllustration 5 shows a cockpit with the steerer aft and in this
case a separated helm Note that all of the steering mechanisms are within the cockpit bridge The quadrant is mounted on the aft side of the rudder
post which necessitates crossing the cables within the pedestal Note the Fig 727Safety Clutch can bring the control cables down just aft of the bridge
deck so they lead directly to the engine and do not get involved with the bridge deck and the moving POSITION Placing the steerer in the middle of
the cockpit or within two feet of either end can give a good balance The crew can be forward or aft whichever makes the boat go best With the steerer
in the relative center of the cockpit the spinnaker winches can be aft and the genoa winches forward when racing this keeps the spinnaker action
behind the helmsman and yet allows the helmsman to assist with the jib winches if needed When cruising the midcockpit arrangement enables the guests
to relax aft and not get involved in sailing the boat while the skipper can steer and tack the boat with ease
IP When placing the pedestal at midcockpit keep at least 1538 cn clearance from the bridge deck or companionway This will p r e w vent a crew member
from having to stand with one foot on the bridge deck a situation The helmsman normally will sit to one side of the wheel or stand behind the wheel
Edsons Helmsmans Seat can fit neatly between the seat risers and its arched center section raises the helmsman for better

MIDSHIP COCKPIT AND IMSTALWTION This guide has been prepared to enable the designer builder and boat owner in planning out the various methods of
installing a wire steering system in a midship cockpit boat Edson offers two types of wire rope systems for the midship cockpit boat the conventional
wire system and the new PullPull Conduit Steering System ideal for boats up to 42 in length Regardless of the type and size of midship cockpit boat
the steering system should be thought out at the time the boat is designed or at least before the interior is in place There are virtually no boats
that can not be adapted to a wire system Whichever system used the advantages of a wire system are many and important The system is simple this makes
it excellent for those boats going offshore or to remote areas A roller chain pulls the rudder to one side or the other If the wire fails you can rig
a new wire Try that with other types of steerers It is in effect a screw nut and bolt philosophy of design The steering will give the boat a
personality There is feel response flexibility and if you want to settle down put on a dampening brake add a simple mechanical AutoPilot These will
give you the best of all worlds PLANNING FOR THE WIRE ROPE SYSTEM When using wire rope and sheaves we are dealing with a series of straight lines or
for the sake of straight connecting rods lllustration 1 shows two basic methods we will call them port and starboard for the sake of simplicity
Starboard The wire is led to starboard just under the deck level over the heads of those passing through the aft cabin passage The wire is then led
aft just inside of the sheer line to a turning sheave which directs the wire into
Port The steering cable goes engine trunk anddown to a sheav engine room floor level then aft to a sheave and up to a sheave a
Needless to say both Port and Starboard can be run the same down or to the side it is all a matter of taking the best course for the available space
and the location of suitable attaching structures for the sheaves The AutoPilot has been attached to a second quadrant mounted on the aft side of the
rudder post and in this case down low With the separate quadrant the boat has in effect two steering systems one automatic one mechanical For further
AutoPilot information see AutoPilot section lllustrations 2 and 3 show the most commonly used method of runnina the wire in a midship Cockpit Boat
The wire is run to either the port or starboard side by using the Edson Fig 607 Adjustable Idler This directs the wire aft a small amount down a small
amount to double sheaves that are mounted on the aft engine room bulkhead Care must be taken to make sure that the wire is clear of the aoorooriate
sail lockers The wire is then directed aft at a level just under the bunk top and on the outside of the backs of the drawers in an area aenerallv
considered to be otherwise unusable In manvcases the wire is run alona the exhaust line trunk Aft the two sheaves are mounted on a stiffening bulkhead
one sheave leads the wire directly to the quadrant the other sheave across the boat to a sheave and then back to the auadrant Care must be taken to
make sure that the wires are led correctly to give the boat directional rather than reverse steering This installation points to the importance of
using existing or planned bulkheads and stifi6 fening for mounting of the sheaves easier stronger a n a i h simpler 4 11 lllustration 2 the
AutoPilot steering cables have been diverted so the pilot can be mounted on a shelf in the aft end of the engine room in an otherwise unused but
generally crowded COCKPIT STEERING 3 shows another form of placing the Pedestal in the MidShip Cockpit Boat The wire is basically led down and run
beneath the aft cabin sole The Pedestal can be placed aft in the cockpit with the possibility of placing the helmsman on a raised seat for better
visibility over the 2
This installation assumes the engine is directly below the Pedestal and it is necessary to place Fig 607 Adjustable Idler under the pedestal to direct
the wire aft a small amount The sheaves at the floor level can be placed on the very aft end of the engine compartment and they in turn will lead aft
to two sheaves placed on a transverse bulkhead directly under the aft cabin floor These in turn direct the wire aft up and out to two sheaves mounted
on the O u n k front bulkheads and then directed into the quadrant Emergency steering can be placed on top of the rudder post by simply removing the
aft cushion and by placing a tiller at this point Some owners prefer an extension that goes through the aft deck to allow placing the tiller over the
aft deck house This is a personal preference but by all means have an emergency method of steering The lllustration 4 installation is used on boats
with passage ways toilets or lockers on both sides of the cockpit foot well With this layout one way to steerthe boat is to run the wires under the
floor of the aft The wire is then directed aft under the floor in the natural V of the hull Aft to two sheaves which can be placed on a simple
structure and then out and up to two sheaves and then into the quadrant Note how the sheaves can be fastened to existing bunk fronts andlor bulkheads
Very important to keep costs in line as well as to keep the structures simple PLANNING FOR THE PULLPULL SYSTEM Edsons new PullPull Steering System is
ideal for midship cockpit boats up to about 42 in length The PullPull System is an alternative to the standard wire rope and sheave installation The
following illustrations show just a few of the many uses of PullPull Steering lllustration 5 shows a Destroyer Wheel with a Fig 338 or 410 Steerer
mounted in a cockpit moldment The moldment houses engine and controls while serving as a table for cockpit entertaining Since the quadrant is mounted
on the aft side of the rudderpost the cables are crossed within this structure for proper steering direction In this case one cable runs along the
port side to the quadrant while the other cable runs directly down the starboard side With this type installation the cables can be anchored to an
existing moldment or plywood Here it is attached to the plywood reinforcement normally placed under aft bunks lllustration 6 shows the Pedestal
installation using the 841 Mounting Plate for attaching the cable The cable is routed along the starboard side under a bunk to a Radial Drive One wire
can run across to a sheave mounted on the other side and back into a regular quadrant if space PULLPULL CABLE AND SHEAVES lllustration 7 shows the
cable running down over the engine and aft under the cabin sole With the sharp bends aft the system converts to a standard wire rope and sheave
arrangement connected to a quadrant or Radial Drive

The Pedestal can be placed at the point up against the ridge deck or in the normal aft position in the cockpit If laced forward it does allow the
helmsman to be protected Q n poor weather by the dodger In addition the engine controls and can all be mounted on the aft end of the house This can
then place all of the wiring in an easily accessible trunk within the main cabin The wire from the pedestal goes down and is Veed slightly to allow
the wires to go to sheaves fastened to the STEERER INSTALLATION This section has been prepared for both amateurs and professionals to assist in the

adjustments for the entire system have been the hub and rudder post for a stainless steel pin The third system is an alternative to cutting a keyway
in solid stock or through drilling for a pin in hollow pipestock The same positioning method as used for the pin must be observed and only after all
final adjustments for the entire system have been made drill and tap for two stainless steel Ysn1952mmcap screws through the hub and well into the
rudder pThe actual drilling operation whether for the pin or for the set screws should be the last step in the entire mm 11615mm HOLE
must be installed if the cut is less than 12 to 15 above the waterline and the boat should be hauled for this operation Where the cut will be made is
determined by the location of the Radial Drive Wheel or auadrant and the size of the idler sheaves see Figs 1 and 2 e a s u r e f r o m under the
cockpit floor either 51127 or 7118cm down depending on your sheave size This locates the wire groove in the Drive Wheel or quadrant With a square mark

LOCATION OF PEDESTAL STEERER After carefully unpacking the Edson equipment lay out all the components and familiarize yourself with the system by
arranging the parts as closely as possible to the order of assembly From the architects drawing or the boats data sheet find the ideal location for
the installation of the pedestal steerer Set your pedestal with the wheel attached at this position and check the cockpit layout Will you be able to
crank your winches Sit and stand comfortably Will the main sheet clear the wheel Adjust your steerer until you are satisfied you have the best
location possible We suggest at least 21 154cm from the pedestal base dead center aft to the rear of the cockpit for standing room Now check the area
under the cockpit floor to make certain the pedestal location chosen will allow freedom of installation for all the components With the pedestal
carefully aligned fore and aft and centered use Edsons Template EB237 furnished with each order to mark the location of the four bolt holes At the
center drill a thru hole 675mmdia This tiny hole will mark the pedestal location when working under the cockpit floor Do not drill any other holes at
this time The small hole can easily be filled should you decide to relocate the steerer PREPARATION OFTHE RUDDER POST I f you are ordering a new boat
with a tiller but plan to add a pedestal steerer at a future date have your boat builder install a stuffing box and key the rudder post This can be
done by the builder at a nominal cost and will make the steerer installation far easier for you when the time comes If your boats rudder i s equipped
with a stuffing box the Edson may be installed with the boat in the water If your rudder post enters through a fiberglass tube from the hull to the
floor a portion of this tube will have to be cut away to expose the rudder post for the installation of the Radial Drive Wheel or the quadrant
Although Edson recommends a stuffing box some boats with high enough freeboard can do without one A stuffing box
I 4 sheaves
A suitable stuffing box should be used to seal the rudder post at the tubing Edsons Fig 697 Stuffing BoxlBearing is preferred as it serves as
additional bearing however hose type stuffing boxes may be used Edson stuffing boxes are available for rudder posts from l1251cm diameter 3189m
diameter and are approximately 41702cm in length The stuffing box must be installed above the water line It mounts on top of the lower cut in the
fiberglass tube see Figs 1and 2 and is heavily wrapped with fiberglass and epoxy resin As on all rudders be sure and place the Fig 697 Stuffing Box
within about 11zl38cm of the bottom of the quaddrant or Drive Wheel and supbort it well for the rudder loads Figs 1 2 6 7 and 8 show typical stuffing
box arrangements With the rudder post back in the boat place the drive wheel or the quadrant onto the post at the determined position NOTE As a simple
safety factor install a stainless steel hose clamp directly under the quadrant or Drive Wheel This will prevent slippage if the quadrant or Drive
Wheel were to loosen in service PEDESTAL SUPPORT

Alignment between the idler and the Drive Wheel is done by raising or lowering the Drive Wheel on the rudderpost Be sure and cut the keyway longer
than necessary for final adjustment When locating the keyway decide whether you will be mounting the Drive Wheel hub up or hub down because the wire
line is not at the center of the hub Cable tension is adjusted using 2 Fig 618 Wire Rope Takeup Eyes as in the standard quadrant system On pedestal
with the rudderpost raked forward or aft you may require a block of wood between the cockpit floor and the idler to lower the idler for a good lead to
the Drive Wheel An alternative sometimes used on racing yachts for ultimate feel is using a 6 idler to lower the wire lead The Drive Wheel is
supplied with a welded steel rudder stop which can be mounted above or below the Drive Wheel forward or aft See Figs 27 thru 32 for installing proper
stops
FIG 2 There are three methods of preparing and attaching the Radial Drive wheel or the quadrant to the rudder post The most secure method for solid
stock is cutting or milling a keyway in the rudder post and the drive wheel or quadrant Be sure and cut the keyway longer than necessary for final
adjustment and the possible addition of an many boats the cockpit floor will require beefing up at the pedestal one method is to install a piece of

wood supports that tie the cockpit to the bottom of the boat and keep the steering loads from wracking the cockpit with resultant bending of the
rudder post 2 The use of an Edson Fig 739 or 740 bracket that bolts to well glassed in wood blocks This system is excellent for those boats that have
an adequate transverse bulkhead to take the loads INSTALLING SHEAVE SUPPORTS Fig 12 shows the time honored Edson Method of glassing in wooden sheave
supports The port side shows the wood support running from the inside sail locker to the bottom of the boat It should be glassed or bolted and made
smooth so it does not catch your sails The starboard side indicates a modification when a quarter berth or other structure limits the use of the
cockpit bulkhead Here the sheave support butts against the cockpit floor or pedestal support Use straight grained mahogany approximately 1Mx 8 and
long enough to reach between the outboard side of the cockpit seat risers and the hull Bond in place with epoxy resin and glass cloth for added
support we recommend a wood same stock spreader between the two sheave supports see Fig 12 INSTALLING BRACKET The Figs 739 and 740 are alternative
methods that can be easier on those boats where the cockpit seat risers are alongside the radius of the quadrant and the pedestal is as shown on Fig
17 This system can be used with the Edson Method or mounting wood blocks for the necessary sheave support The preferred sheave bracket installation
shown in Fig 17 uses approximately 21 5crn by 12130cm to 18146crn wood blocks glassed into the sail locker sides of the cockpit floor When necessary
to bolt thru the cockpit floor keep as wide as possible with the bolts as near the edge of the cockpit gutter as possible This reduces the chances of
oil canning the floor and resulting cracking of the gel INSTALLATION When installing the PullPull System the two conduits can either be routed port
and starboard Fig 19 or both down the same side Fig 20 If space is at a premium lead both conduits down the same side and then route one wire across
to a sheave mounted on the opposite side and back to the quadrant Fig 21 The conduits must be terminated by drilling a 3hr1 hole in either an existing
moldment or a plywood bulkhead Anchor the conduits in place by using the nuts and washers supplied Fig 22 When terminating the conduits make sure they
lead the wire rope properly either to the steerer or to the correct groove of the Quadrant or Radial Drive The PullPull conduit has a minimum bending
radius of 8 and for the smoothest steering try to keep the number of sharp bends to a minimum Once the system is hooked up tighten the wire rope to

two feet longer than the required STEERER INSTALLATION THE RUDDER STOPS The steering system must have stops to pick up the loads at the hard over
position Although Radial Drive Wheels and Sheave Brackets are supplied with rudder stops the preferred method is to install the rudder stops into the
hull independently of the steering system Rudder stops must be installed to prevent the rudder from hitting the hull or the chain adapters from
damaging the sprocket Be sure the stops are strong for they will take a lot of strain at one time or another during the life of your boat The
following sketches show the best methods of installing the EDSON PEDESTAL MAINTENANCE GUIDE
All Radial Drive Wheels are provided with a rudder stop The stops can be mounted fore or aft and to either the top or the bottom of the drive wheel
Figs 27 and 30 Blocks of wood should be fiberglassed in place for the stop to hit Stops must hit squarely and as low on the stop as possible The best
rudder stop arrangement Fig 37 uses a tiller arm or its equivalent as a stop This keeps the stops independent of the steering An alternative method
for the rudder stop is to place a straight grained mahogany beam athwartships and cut out two notches for the stop to hit squarely keeping the total
travel of the Drive Wheel between 60 and 70 degrees Fig 3 2 FLOOR

bearing holding the rudder up in the guide has been prepared to assist you in the proper maintenance of your Edson Steering System To properly
maintain the moving parts in the top of the pedestal it is necessary to remove the compass and its cylinder For proper alignment when reinstalling the
compass we recommend placing 3 or 4 lengths of tape on the pedestal and compass as shown below Slit the tape when removing compass align the strips of
tape when reinstalling the compass for visual compass realignment Your compass MUST then be checked for accuracy Lubrication of needle bearings should
be done by squeezing Edson Fig 827 Teflon Lubricant into the holes located on top of the bearing housings inside the pedestal bowl Spin the wheel when
squeezing the lubricant in to make sure the entire bearing is serviced Winch grease or water pump grease can be used as an alternative but dont let
the bearings run dry Do not over grease as it will run onto the brake pads Oil the chain with 30 weight motor oil Do not grease chain as it does not
penetrate the links Inspect the condition of the wire tension of the wire and lightly oil Edson recommends placing about 5 layers of Kleenex on the
palm of your hand squirt oil on the tissues and lightly oil the wire This will lubricate the strands but will also flag a broken or hooked strand by
tearing off a small section of tissue fyou do have a wire break replace the wire immediately See Edson Fig 775 wire and chain repacement kits Calltion
Wire splinters can cause painful cuts Replace the wire after5 vears If still aood keeo the old wire on board as a soare o check for proper wire

4 DIAPHRAGM THE PROPER BILGE PUMP
When a boat springs a serious leakand water i s rapidly rising above the engine the Bilge Pump becomes the means of saving the boat No yacht owner
wants a sinking boat let alone have a little water over the floor boards If such a situation does arise the boat owner should always be well prepared
for any type of emergency with a large capacity Bilge Pump For handling large volumes of water the Diaphragm Pump is pump on the market If you
currently have an electric bilge pump use it for that daily job however we strongly recommend that you have in addition a hand operated Diaphragm Pump
Your pump should always be functional no matter what the conditions of weather or what shape the boat is in Unlike many hand pumps of the old Navy
piston type design the Diaphragm Pump will move an exceedingly large volume of water in a short amount of time without exhausting you or your entire
crew The Diaphragm Pump is also virtually clog proof Most anything that will pass through the hose can be pumped The larger the pump the more debris i
t can handle There are many different Diaphragm Pumps on the market most ranging within the 341119m to 112 38cm pipe size In most cases these small
Diaphragm Pumps are only good fo small jobs Dont forget a fiberglass boat either doesnt leak at all or leaks far too much Edsons two inch Hand

getting completely exhausted In planning your installation considerthat adequate room is given for legs feet hands etc so that one can brace
themselves easily against the boats motion It is very important to mount the pump out of the way yet instantly available The suction hose should be as

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
