angle of the dangle

Gotta love these newbie questions. Straight from the sailing Anarchy forum, brought to you by Marlow

We are getting better at racing – good enough to know we dont know shite 🙂

I have never paid too much attention to heel, I knew its better than flat, sometimes, but now I know there must be a good heel angle at certain wind speeds and angles. But I dont know what it is.

Is there a scientific way to do this? We are getting new sails including a code0, so we have to build new polars to get some target speeds and to find out how good we are. But I dont tknow how to compensate for trim..I cannot do every angle with all the heel, so I’d be glad if there is a scientific explanation…
