A question which I can't seem to find on a search of the net, how do you determine what mast rake you should have on your boat, I've tried quite varying degrees of rake and to be honest you have to move it a long way back before any sort of lee helm starts to appear. My guess is that there must be an optimum relationship between the balance of boards and rudders before things are not nuetral and the boat crabs up the pond.

Is there any sort of visual aid like the wake perhaps. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
