You re going to find that both steering and sail adjustments will be the major factors determining speed around a racecourse. The backstay should be eased all the way to keep the jib full. As the breeze increases the backstay will need to be tightened and the jib sheet will need trimming. The lead may change one hole aft as the breeze gets to about 6 knots. As the wind increases to the top end of the sail, continually increase backstay tension.
Maximum backstay puts the bridle blocks about level with the stem pulpit.
The boat is very powerful and likes to carry large amounts of sail. In very heavy air, heeling can be reduced by easing the jib sheet and moving the jib car one hole aft. The main should be rimmed so the top and second batten up are roughly parallel with the boom. The exceptions are very light and very heavy air. In light air the traveler should be rimmed up to bring the boom up to centerline.
