On the rooster upwind dvd steve cockrill goes on a great deal about how it can be really beneficial to sail with some windward heel in lightwind. He said that what you do is head down, heel to windward, and push the tiller away from you, without pinching too much. Apparently, the pushing on the rudder alters the direction of waterflow across the daggerboard, and suddenly, after some squirreling, it feels like someones pulling on your daggerboard to windward. The bearing off gives you speed and the heel gives you height. He said that only a few can accomplish this feat and do it really well. Have any of you tried this and are there any tips you can give me?
