Chapter 2: Using the Tiller Pilot 13To switch back to AutoSeastate, press -1 and +1 again.Note:The autopilot reverts to Automatic Deadband Control each time you select Standbymode.Operating hints – trim changesCAUTION:Only make major course changes when steering MANUALLY. Thisensures that the boat will safely clear any obstructions or otherboats, and you can take into account the changed wind and seaconditions on the new heading before engaging the autopilot.Large course changes which change the apparent wind direction can producelarge trim changes. When a sudden trim change occurs (for example due toweather helm or sail imbalance) there will be a delay of up to one minute beforethe automatic trim applies rudder to restore the locked heading.In these situations, the autopilot will not immediately assume the new automaticheading, and will only settle onto course when the automatic trim has been fullyestablished. To minimize this problem, use the following procedure to makemajor course changes:1. Note the required new heading.2. Press standby, remove the pushrod from the tiller pin, and steer manually.3. Bring boat onto the new heading and fit the pushrod back onto the tiller pin.4. Press auto and let the boat settle on course.5. Bring your boat onto the final course in 1° steps using -1 or +1.Gusting conditionsIn gusting conditions, the course may tend to wander slightly, particularly if thesails are badly balanced. By improving sail balance, you can improve coursekeeping.If you take the following precautions, the autopilot will be able to maintaincompetent control even in gale force conditions:• Do not allow the boat to heel over excessively.• Ease the mainsheet traveller to leeward to reduce heeling and weather helm.• If necessary, reef the mainsail a little early.• It is also advisable (whenever possible) to avoid sailing with the wind deadastern when there are very strong winds and large seas.• Ideally, the wind should be at least 30° away from a dead run.
