Halyard wraps usually occur in wave action when lead angle Prevent Halyard WrapTo prevent wraps the halyard must exert a slight pull to the rear This allows the foils to turn while halyard remains Sail must be 037tted to foil length before using Halyard WrapThe most serious problem with furling systems occurs when the jib halyard wraps around the headstay foil Halyard wraps will keep you from furling or unfurling and may cause serious damage to the unit and the halyard WARNING In severe cases a halyard wrap can cause loss of control of boat andor headstay can break suddenly Make A professional rigger must carefully inspect the masthead area using a secure hoisting method Inform rigger that there has been a halyard wrap so they can avoid an accident by relying on standing rigging or halyards Inspection must be done while rigger is suspended from a separate crane or mast must be lowered to perform inspection Some professionals may rig a new line through internal masthead sheaves to serve as a temporary headstay to hold mast in place Wire rod rigging terminals toggles clevis pins or cotter pins must be inspected and replaced if they show any WARNING Do not go aloft on boat222s halyards if there has been a halyard wrap Do not use boat Damage to halyard headstay stay terminals or connections as a result of a halyard wrap may cause these parts to break suddenly causing mast to fall down while person is aloft Sailing or motoring with boat after a wrap can result in the headstay breaking and mast falling down Before using boat have a professional rigger inspect and replace parts as necessary using following methodsIf Halyard WrapsIf halyard wraps do not force unit to turn Attempt to open sail by carefully furling in and out a little at a time If sail will unfurl lower it by releasing jib halyard Severe halyard wraps can only be cleared by a professional going If sail will not furl or unfurl try to remove jib sheets and manually wrap sail around prevent wraps jib halyard must pull slightly to rear On most boats On some boats halyard sheaves are located too close to headstay and Halyard restrainers should be used only when required by masthead geometry Restrainers tend to limit sail luff length and may cause problems if not installed properlyIf your boat needs a Halyard Deflector use Part No 7302 or a Halyard Restrainer use Harken Part No 944Restrainer should be mounted as high as possible on face of mast The restrainer should deflect halyard as little as possible or you may experience difficulty in tensioning sail luff friction when furling and possible damage to foils To decrease deflection angles shorten sail luffTip Boats used in charter service should have a halyard restrainer regardless of masthead TensionTip The luff foil system supports sail along its length so halyard tension is used only to shape sails not to support them Use enough halyard tension to remove some wrinkles along luff of sail Do not tension halyard enough to cause vertical wrinkles in luff of sail Tension to adjust position of draft in sail to suit sailing conditions Halyard should be firm but not tight If in doubt release halyard tension To protect sail ease halyard when boat is not in useIf the your sail luff is not long enough to position halyard swivel high enough to create an 822610260 angle as shown you must add a pendant Pendants should be made of plasticcoated wire and be permanently attached so sail height will be correct Adjustable length pendants are not acceptable as they might not be adjusted 2 Position halyard swivel correctly near top of headstay 4 Tie a piece of rope to sail tack6 Tension sail8 Repeat procedure for every jib in your sail adjusters allow headstay tension to be varied to change sail shape to match conditions They permit a very tight headstay to be eased when boat is not in use For best performance consider adding a backstay adjuster either a block and tackle a mechanical adjuster like those offered by Harken or a hydraulic to keep headstay tight for best performance when furling or reefing the halyard is tensioned If not backstay adjuster may increase halyard tension and could Racing boats often slack the headstay completely when sailing downwind Check to be sure that foil does not jam against upper headstay terminal when backstay is released To prevent this it may be necessary to shorten foil slightlyOn many boats it will not be possible to attach spinnaker halyard to bow pulpit or it may be On some boats the spinnaker halyard lays across headstay and will catch on halyard swivel foils or jib halyard To prevent problems it may be necessary to install a masthead bail to move spinnaker halyard block forward and to one side Boats with external halyards may find it necessary to flip both ends of spinnaker halyard behind spreaders Headstay TensionA furling system will work best if headstay is tight A loose headstay is difficult to rotate and can cause To adjust headstay tension remove sail and furling line Tip Before adjusting headstay tension slack Spinnaker halyards occasionally cause problems WARNING In severe cases spinnaker To furl or reef ease the jib sheets and pull In very light air it may be necessary to place luff sail by The furling line should pull readily The amount of force required is related to amount of wind but a Unit 1 should never require use of a winch to furl If the sail will not furl or if furling requires a great deal of effort there is a problem with system Consult the Guide on Page 33 Do not use a winch to force a system to turn If you are certain that the system is operating properly you may use a winch to make furling easierbelow furler so it is 2 610 mmside as sun coverTip New sails are often stiff and may hang up on prefeeder during raising Do not force sail when it hangs up227lower and remove twist Sails break Most people will use one multipurpose genoa for all their sailing but it is not good seamanship to go offshore Heavyair working jibs and storm sails may be used with your unit These sails need to have luff tape added to allow These sails will generally require pendants to ensure that halyard swivel is properly positioned at top of headstay A sail may be partially furled before you resume Many sailors find it helpful to place marks on foot of sail so that they can reef to a variety of predetermined jib sizes This allows marks to be placed on jib lead tracks or toe rail so that lead block position can be changed to correspond Sails are generally reefed to balance boat and to reduce heeling moment Sails may also be reefed to improve visibility or to slow boat while sailing When furling the sail completely make sure sheets and furling line are Check amount of line on the spool compared to the furled sail a Two to three wraps of jib sheet wrapped around sailb Two wraps minimum of line wound on spoolRemember sails furled in light wind and left loosely secured can be a problem IMPORTANT Remove sail from furler if extreme winds are predicted IMPORTANTCheck all points above227a b c and d227when leaving boat to A loosely rolled sail can catch wind in a storm Sheets or furling lines can loosen as winds increase and allow furler to unroll If no wraps of line are on spool the line deadend can break the drum when the boat motors Be sure mooring lines are not placed across furling line where they may Add more wraps of Untie jib sheets and keep sail completely rolled Secure with Turn spool to unroll a Add more wraps of line Turn spool to add a Race conversion
