I've sailed the F16, uni, at 215-220 lbs. for over a year. I don't feel my weight puts me at a disadvantage. MY skill level, well. . . that's another story.

Sailing uni is physically exhausting when the wind comes up. If you expect to sail well you need to be in good shape. Fatigue causes poor decision making, which can put you upside down in a hurry! <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
