Gusty conditions
In gusting conditions, the course may tend to wander slightly,
particularly if the sails are badly balanced. A significant improvement
in course keeping can always be obtained by improving sail balance.
Bear in mind the following important points:
ï Do not allow the yacht to heel over excessively
ï Ease the mainsheet traveller to leeward to reduce heeling and
weather helm
ï If necessary, reef the mainsail a little early
It is also advisable, whenever possible, to avoid sailing with the wind
dead astern in very strong winds and large seas.
Ideally, the wind should be brought at least 30∞ away from a dead run
and, in severe conditions, it may be advisable to remove the mainsail
altogether and sail under headsail only.
Provided these simple precautions are taken, the autopilot will be able
to maintain competent control in gale force conditions.
