Gusting Conditions - Raymarine ST3000 Owner's Handbook Manual

Chapter 2: Using the Wheel Pilot
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 minimize this problem,
use the following procedure to make major course changes:
1. Note the required new heading.
2. Press STANDBY , disengage the clutch, and steer manually.
3. Bring boat onto the new heading and engage the clutch.
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 conditions

In gusting conditions, the course may tend to wander slightly,
particularly if the sails are badly balanced. By improving sail balance,
you can improve course keeping.
If you take the following precautions, the autopilot will be able to
maintain competent 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 dead astern when there are very strong winds and large seas.
Ideally, the wind should be at least 30° away from a dead run.
In severe conditions, it may be advisable to remove the mainsail
altogether and sail under headsail only.
