Well I would loosen everything except for the diamonds and start to haul everything in on whatever tack you feel is the problem.Remember though you are not sailing in a straight line( I constantly forget this )when the puff hits drive off even to weather a little with it the boat will rocket ahead also your wieght forward I feel is important as this boat does naturelly balance out . It is the constant serpentine with the puffs to weather that support speed to speed aspects. Otherwise the speed-stall-speed triangle will squash your day. Anybody else in on this?
