Page Waypoint Arrival And Advance Waypoint arrival and advance Arrival As the boat arrives at the target waypoint the navigation aid should manually or automatically select the next target waypoint. This shows the new bearing to the next waypoint and the direction the boat will turn to acquire the new track.

Press auto to continue on the same heading, or standby to return to hand steering. Skipping a waypoint — Check for fixed positional errors and compensate for them. Verifying computed positions Always verify the computed position with a dead reckoned position, calculated from the average course steered and the distance logged. It uses wind trim to eliminate the effects of turbulence and short term wind variations.

This provides smooth and precise performance with minimal power consumption. Check that it is safe to turn onto this course. To accept this apparent wind angle, press standby and auto together within 7 seconds. Note: If you do not accept the previous wind within 7 seconds, the autopilot will lock onto the current apparent wind angle.

Note: Before you use the AutoTack function in Wind Vane mode, you must make sure that the wind vane was centered accurately at installation.

Introduction 1. This autopilot system will steer your boat to a heading automatically, accurately and reliably. Standby : autopilot off see page 7. Auto : autopilot engaged and locked onto a heading see page 6. Track : autopilot engaged and maintaining a track between two waypoints created using a navigation system see page Wind Vane : autopilot engaged and maintaining a course relative to an apparent wind angle see page You can connect it to additional fixed or handheld SeaTalk autopilot control units located at secondary steering and control positions see page The sections in this chapter explain how to use the basic functions on your autopilot:.

After each trip, flush inside the drive unit by inserting a hose pipe in the free slot on the back cover. This will prevent any build-up of salt on the drive ring and bearings.

AutoTack to port by pressing the -1 and keys together. The information displayed on the bar graph varies according to the autopilot mode:. Operation Basic 2.

Steady the boat on the required heading. Wheel Pilot: Engage the wheel drive clutch by rotating the clutch lever clockwise so the lever engages fully onto the locating pip. Tiller Pilot: Place the pushrod end over the tiller pin.

Press auto :. Autopilot course control makes it easier to sail a boat, but it is NOT a substitute for good seamanship. Press standby. Disengage the autopilot to return to hand steering:.

The last heading is memorized and can be recalled see page 9. Select a course change in the appropriate direction. When safely clear of the obstacle, you can either:. If you have steered the boat away from the selected locked heading for any reason for example, executing a dodge maneuver or selecting Standby , you can return to the previous locked heading as follows:.

Press auto for 1 second. Note: The direction-to-steer indicator shows the direction the boat will turn. To accept the previous heading, and resume this course, press auto within this 7 second period. Note: If you do not press auto while the display is flashing, the autopilot will maintain the current heading. This ensures that the boat will safely clear any obstructions or other boats, and you can take into account the changed wind and sea conditions on the new heading before engaging the autopilot.

Large course changes which change the apparent wind direction can produce large trim changes. When a sudden trim change occurs for example due to weather helm or sail imbalance there will be a delay of up to one minute before the automatic trim applies rudder to restore the locked heading.

In these situations, the autopilot will not immediately assume the new automatic heading, and will only settle onto course when the automatic trim has been fully established.

To eliminate this problem, use the following procedure to make major course changes:. Note the required new heading. In gusting conditions, the course may tend to wander slightly, particularly if the sails are badly balanced. If you take the following precautions, the autopilot will be able to maintain competent control even in gale force conditions:. During normal autopilot operation in any mode you can make temporary adjustments to:.

Note: You will lose these temporary changes to response level and rudder gain whenever the system is powered off then on again. You can make permanent adjustments in Dealer setup see page This setting causes the autopilot to gradually ignore repetitive boat movements and only react to true variations in course. This provides the best compromise between power consumption and course keeping accuracy, and is the default calibration setting.

This setting provides the tightest course keeping possible. However, tighter course keeping results in increased power consumption and drive unit activity. Press disp or wait for 5 seconds to return to the previous display.

Note: See page 96 for instructions on how to check that the rudder gain is set correctly. When you have dealt with the first alarm, the autopilot will display the next alarm.

It shows whether the deviation is to port or starboard. To cancel the off course alarm, press standby to return to hand steering. Check whether your boat is carrying too much sail, or whether the sails are badly balanced. You can usually significantly improve course keeping by improving the sail balance.

The alarm clears if the heading recovers, if you change the course, or if you change the operating mode. This occurs when:. When you have done this select Auto, Track or Wind Vane mode. Note: You cannot engage Auto mode directly from Watch mode — pressing auto will only reset the Watch timer. If you want to enter Auto mode, you must first exit Watch mode see below. If the autopilot is in Track mode, it will sound the Waypoint Advance alarm to notify you of the change in waypoint. Note: When the display lighting is off, the control unit still illuminates the keys at a courtesy level.

Press disp for 1 second from any mode to access the LAMP screen and turn on the lights. Note: LAMP 3 is the brightest setting.

The display automatically returns to the previous mode if you do not press a key for 7 seconds:. Note: You can also adjust the lighting level from any other SeaTalk instrument or control unit connected to SeaTalk. Note: When you switch off the unit you lose any changes you have made to the lighting. The sections in this chapter explain how to use the more advanced functions on your autopilot:. Operation Advanced 3. Note: You can only use Track mode if you have connected the.

The autopilot computes any course changes to keep your boat on track, automatically compensating for tidal streams and leeway. To select Track mode, press the track key with the autopilot in Auto mode.
