First, do as Rick has suggested. Second, you can transfer your weight forward off the wind and still steer with your hands - you can lie down with your feet forward as easily as the other way around. Third, if you can get to P-I-B this summer, you will definitely learn a lot. Fourth, weight always makes a difference - pushing more than an extra cubic foot of water out of the way every boat length simply requires more energy. Laws of physics don't change for sailboat races. Finally, consider doing yourself a favor by losing some weight. Google your height/weight combo to see where the recommendation lies. It could be the best result that your sailboat racing ever produces! I would always welcome luck but more important is knowledge and preparation. Ever notice how lucky the best prepared people are? You can do it!!
