WINDWARD PERFORMANCE
All corsair models will point very high if set up and sailed correctly, but this can also be
very dependent on the crew’s skill. It is possible to point just as high as a mono hull, but
this may not be the fastest way to windward. A good multihull is capable of much higher
speeds to windward than a mono, which also brings the apparent wind forward, to
where pointing will is much greater.
One thing avoid is over sheeting the headsail, as while pulling this on very tight will
guarantee a good pointing angle, the boat speed may be slow. The correct way is to let
the sheet out 1”-2” from being tight on, so that the curve of the headsail leach matches
the curve of the mainsail. It should then not backwind the main, and your pointing angle
and boat speed should both be excellent.
Once you have achieved good boat speed, then experiment by tightening sheets very
slightly, pointing slightly higher, while trying to maintain the same boat speed.
The mainsail traveler should be around 6” to windward in lighter conditions, then
around the centerline in moderate winds, and as the wind increases, moved outboard
slightly and more mainsheet tension applied. In very strong winds the mainsheet should
be pulled on as tight as possible. Stand above it and pull it on as hard as you can - most
sailors don’t have this tight enough in strong winds. A tight mainsheet helps keep the
forestay straight for good pointing ability.
If the jib is back winding the main, open the slot, by moving the traveler a little more to
center. Keeping an open slot between jib and main is crucial to good windward
performance, as any back winding of the main will choke the boat. Equally as any
important, the jib must be relatively flat with
no hook
in the leach, and not over
sheeted. Leach battens are highly recommended to keep the leach flat.
If set up and sailed correctly, a Corsair trimaran will match the windward ability of the
best mono hull racers, 20% to 30% larger. Pointing high and going fast is one of the
hardest things to achieve in any boat, but with a little care and tuning a Corsair is one of
the best.
Achieving good windward performance can be very satisfying, but it does depend on a
lot of factors being right.
