Until you are familiar with interpreting the chart display, you should take
every opportunity to compare displayed objects with visual targets, such as
buoys and coastal structures. You should practice harbor and coastal navi-
gation during daylight and in clear weather conditions. RayTech simulator
mode will also help you gain experience.

5.2 The chart screen
The chart is a digitized image of the paper chart for the selected area - see
"RayTech default screen" on page 32. The chart shows objects, such as
landmasses, navigational objects and depth contours.
The amount of detail shown varies for different chart types and areas
covered. The scale at which the chart is shown also affects the amount of
detail shown. Cartographic information is also available for objects marked

Chart quilting
When you are working with raster format navigation charts, the Quilting
button allows you the option of using a single chart image, or seamless
charting.
With quilting enabled, the system default for any opened chart window,
RayTech stitches together all of your raster cartography, connecting the
edges of the different charts together. This means that no manual interven-
tion is required to switch charts. You simply pan to the area you wish to
see. Chart detail will be affected as you range in or out to view larger or
smaller scales.
When you are using the quilting function, the best available chart for the
area you are in will always be displayed. This information is based on your
boat's position, the focal point of the cursor and the range scale selected.
As you pan or zoom around the chart, cartography will be continuously
displayed.
With quilting turned off, the chart at the focus of the display will be shown

Coastal roads
When you display a chart with an aerial photo overlay major coastal inter-
state, state highways and other major roads are shown.

         Highway/ Minor road


                                                         Interstate highway/ Motorway

                                               D8759_1




The ability to view roads depends upon the level of transparency that has
been selected for the aerial overlay. As the overlay visibility is decreased
the roads will fade from view.

US inland waterways
Chart coverage of major US inland waterways such as the Great Lakes and
Lake Okeechobee are now included in Platinum cartography.

Using 2D and 3D charts together
If the area in which you are navigating is unfamiliar to you, or visibility is
poor, working with 2D and 3D chart applications on the screen side by side
can give you extra confidence and help you to find out what is around you.
With your RayTech page set up to view the two applications together a
comprehensive view of the surrounding area is show.
As with all multiple page sets the active window is indicated by a red
border. To make any changes in an application it must be the active
window.

Navigating with 3D Charts
To navigate to a new waypoint or use a new route, you should first create
the waypoint or route on your 2D chart.
Once navigation is activated in the normal way, the 3D chart displays:
 The active waypoint using the same symbol as the 2D chart.
However, it should be remembered that a route can only be edited using a
2D chart. Any changes that you make on the 2D chart are automatically
shown on the 3D chart.

9.1 Introduction
Tide and current data is available for many areas on the chart application
of RayTech.
The predictions displayed for Tides and Currents are sufficiently accurate
under moderate weather conditions, for the coastal areas served by the
reference station, to be used for navigation planning. However, certain
weather fronts and storms can alter tidal patterns and influence predicted
times and heights.
In addition and in common with all similar products, tidal data is calculated
algorithmically and may, in some regions, be subject to error. If exact tidal
heights or times are critical to a particular passage, Raymarine recom-
mends that details are checked against a Tidal Almanac published by the
appropriate marine authority.
Note: RayTech uses your PC or laptop's system clock for the date and time
                                                                                4. Scroll and highlight the required area. Click OK. The area is now set to

9.2 Tides
Tide height data - see page 62 - is a prediction for maximum and minimum
tide heights over a 24 hour period for a selected station in a selected
region.Data for sunrise and sunset is also provided.
As long as you have a valid global positioning system (GPS) time /date
signal being received by RayTech, the graph will automatically default to
showing today's tides. If there is no signal then the graph will default to an
earlier date.

9.3 Currents
Current flow data is a prediction for maximum and minimum current flow
over a 24 hour period for a selected station. Data for sunrise, sunset and
moon phase is also provided.
When using current information the default is always the last selected
station. As long as there is a valid GPS time/date signal being received by
RayTech, the graph will automatically default to show today's currents. If
there is no valid signal the graph will default to an earlier date.

(EBL) is used to determine the range and bearing (respectively) of objects
detected by the radar.
A standard VRM is displayed as a circle with its center on your boat's posi-

radar screen. Both are shown as dotted lines. If you range in or out, or
offset the center of the display, the original setting of the VRM/EBL remains
unchanged. RayTech allows two VRMs/EBLs to be displayed at the same
time.
When a VRM/EBL pair is active, their bearing and range can be displayed in                                                                   VRM

Radar echoes from waves around your boat can clutter the center of the
radar picture, making it difficult to detect real targets. Several factors can
effect the level of clutter you see, such as the mounting height of the radar,
weather and sea conditions. The sea clutter curve settings adjust the
system's sensitivity to sea clutter. The steepest setting is 1 and the shal-
lowest is 8. The default setting is 1.
Parking offset (Open Array scanners)
The default parking offset is 0 degrees: the scanner aligns with the
pedestal, facing forwards.
With parking offset selected you can adjust the parking offset from 0 to
358 degrees in steps of two degrees.
This setting change is only available when the digital radar is set to Off or
Standby. The changes you make are applied the next transmit cycle.

Orientation
Radar orientation refers to the relationship between the radar display and
your direction of travel. There are three orientation modes:
     Head up
     North up
     Course up
These orientation modes are used in conjunction with motion modes (see
page 92) to control how your vessel's progress is shown on screen.

12.2 What is AIS?                                                                  nation etc.

AIS uses digital radio signals to broadcast `real-time' information between
vessels and shore based stations via dedicated VHF frequencies. This infor-
mation is used to identify and track vessels in the surrounding area and to
provide fast, automatic and accurate collision avoidance data. AIS will
augment your radar application, as it can operate in radar blind spots and
can detect smaller AIS fitted vessels.

WARNING: Smaller vessels do not have to be fitted with AIS
and whilst it is mandatory for larger commercial vessels to
carry AIS, its use is not. You should not therefore assume that
your AIS will display ALL vessels in your area. Due prudence
and judgement should be exercised.

WARNING: AIS should be used to complement not substitute
radar.

Local AIS alarms
When the connected AIS unit generates an alarm, your system displays a
local alarm message.

13.2 The sonar screen
When you first view the sonar screen, a scrolling bottom graph is displayed.
This is a graphical representation of the echoes seen by the sounder
module. As time passes this image scrolls from right to left and becomes a
record of the echoes seen. Default Sonar Screen - page 131 shows a typical
sonar picture.
The images at the right of the screen are the most recent echoes. Some
echoes indicate fish and others show the bottom. Bottom structure struc-
tures, such as a reef or shipwreck will also be indicated.

TVG
Time Varied Gain (TVG) reduces surface clutter by reducing the gain in the
top 100 ft. of the display and is useful for reducing noise, such as that
generated by boat movement and floating debris that often appear in
shallow water. A low TVG value has little effect on gain in shallow water; a
high TVG value decreases the gain in shallow water so that only the stron-
gest echoes are displayed. You can adjust TVG manually or automatically.

Color Threshold
Color threshold determines the amount of color you see displayed on
screen. Setting the threshold to 100% gives you the full range of colors
shown on-screen. The lower the setting the less colors are displayed.
To adjust the gain controls:
1. Click Presentation.
2. Click Gain. The gain control softkeys are displayed.
3. Click the appropriate softkey to adjust the gain control settings.

13.7 Getting a clear picture of the bottom
You can get a clearer picture of the bottom using the Bottom Lock function.
The normal scrolling bottom display provides a top-down view, referenced
from the surface of the water. Bottom lock shows a water column of fixed
height, referenced from the bottom that appears flat. It removes bottom
detail to provide an image of objects directly above the bottom and is
useful when you are looking for objects or fish that are feeding close to the
bottom.
You can select the bottom lock image to be vertically split with the
scrolling bottom image, or to replace the scrolling bottom image.
The bottom lock image - see Bottom lock - page 119 - appears at the left
hand side of the screen. The bottom appears as a straight line, but some
features may extend above this line. Depth from the bottom is referenced
at the right of the split screen, with the bottom shown as zero. Actual
depth is shown in the bottom left of the screen. Bottom lock range is
adjusted using the RANGE button.
To display bottom lock image:
1. Click on the preset to change.
2. Click the Select View softkey until Bottom Lock is displayed.
3. Select the Bottom Lock softkey to display the Bottom Lock settings.
4. Click to select the way in which bottom lock is displayed.

13.8 Getting a live image from below the boat
The normal scrolling bottom display shows a historical record of sonar
echoes. The A-Scope screen - see A- Scope - page 121 displays raw sonar
data direct from the transducer beam.
This gives you a real-time image of bottom structure and any fish directly
below the transducer. This function is useful in showing the strength of
echo returned from an object. A-Scope also displays the patented Bottom
Coverage width indication.
A-Scope can be displayed in three modes:
    Mode 1 -the image is angled outward as the signal width, indicated
     with dotted lines, increases with depth.
 Mode 2 - the image expands to take up the entire A-Scope pane, giving
     greater detail.
 Mode 3 - the left hand side of the Mode 2 image is expanded to the
     entire pane. This mode gives the greatest resolution.
If a bottom lock or zoom image is displayed, selecting A-Scope automati-
cally switches them off. If you have split frequency images displayed, A-
Scope is automatically displayed in both panes.
To display the A-Scope image:
1. Click on the preset to change.
2. Click the Select View softkey until A-Scope is displayed.
3. Select the A-Scope softkey to display the A-Scope settings.
4. Click to select the way in which A-Scope is displayed.

A Waypoint is a position entered on a chart as a reference, or as a place to
go. All waypoints placed on the chart plotter are stored in a waypoint data-

waypoint.

Routes
A route is made up of a series of waypoints. To make a route a series of
waypoints is placed on the chart, or can be selected from the Waypoint
List.
When a route is created it becomes the current route and is displayed on-

The radar indication may not be similar to your visual observation; a nearby
small object may appear to be the same size as a distant large object on
the radar. However, with experience the approximate size of different
objects can be determined by the relative size and brightness of the echoes.
Some targets, such as buoys and small boats, can be difficult to differen-
tiate, since they bob and toss about in the waves and do not represent a
consistent reflecting surface. Consequently, these echoes have a tendency
to fade and brighten, and at times, to disappear momentarily. Buoys and
small boats often resemble each other, but boats can usually be distin-
guished by their motion.
Not all radar echoes are produced by hard navigational items. Some echoes
may be received from irregularities on the surface of the water, particularly
at close range (sea clutter), or from rain or snow either around the boat or

Interference

                   When two or more radar-equipped boats
                   are operating within range of each other,
                   mutual radar interference can occur. This
                   usually appears as a spiral of small dots
                   from the display center. This type of inter-
                   ference is most noticeable at long ranges.

The sonar application uses a Digital Sounder Module (DSM) to process
sonar signals from a suitable transducer and provide a detailed underwater
view.
The transducer located on the bottom of the boat sends pulses of sound                                                            D7058_1

The DSM processes these echoes and sends data to the sonar which
displays a visual interpretation of the underwater view. The strength of
echoes is indicated on the display by different colors. You can use this
information to determine the bottom structure, the size of fish and other
objects in the water, e.g. debris or air bubbles.

Appendix G: Glossary of terms

Abbreviation   Meaning               Definition

               Active route          The route on a chart which is being used for navigation.

Awa            Apparent wind angle   The angle of wind as measured by your boat's instruments.
                                     When the boat is stationary, Awa is equal to True wind angle (Twa). When the boat moves, Awa
                                     is always less than Twa.
                                     Awa is measured in degrees.

Aws            Apparent wind speed   The speed of wind as measured by your boat's instruments.
                                      When sailing upwind, Aws is always greater then True wind speed (Tws). When sailing down-
                                     wind, Aws is always less than Tws.
                                      Aws is measured in knots.

COG            Course over ground    Your direction of movement relative to a ground position.

CTS            Course to steer       The heading you need to maintain in order to reach your destination

Tab            Rudder tab            An adjustable section of the rudder that allows the rudder to be corrected for lee or weather
                                     helm as appropriate.
                                     Adjustment is measured in degrees.

Twa            True wind angle       The angle between True wind direction (Twd) and the centerline of your boat.
                                     Twa is measured in degrees.

Abbreviation   Meaning               Definition

Twd            True wind direction   The magnetic direction that the wind is coming from, calculated to appear as though measured
                                     from a stationary boat.
                                     Twd is measured in degrees.

Vmg            Velocity made good    The boat's speed towards or away from the Twd, used to measure performance relative to
                                     upwind/downwind targets.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
