Thanks, Alex. I spent yesterday -- a very rare light-air day -- fiddling with sail trim and crew weight and centerboard position on my dinghy. I found on a small boat like that, the most influential factor was degree of heel. The boat would head up quite sharply if I moved to the lee bench, fall off if I hiked it to weather. Was I stalling the sails that way, & that's why it had weather helm?
Funny, the boat has a slight weather helm in low winds, but a vicious weather helm in high winds. May be an effect of the fractional rig? Or is it just the 40 degree heel making it dig hard to weather? In winds over 15 kts, we have to really luff the main to prevent rounding up.
