After modifying wind surfing sails for a while I decided to try making my own dacron sails from scratch. I repurposed an old set of Hobie 16 sail cloth but no part of the original sail design remains. I removed all the broad seeming with intention of making the sails flatter but maybe took this a bit far as they have no camber/draft now. Now realizing I should have maybe left some shallow camber I'd like to try again but I can't find any specs to use as a starting point. Does anyone have any specs or suggestions for draft, position of maximum draft, entry and exit shapes that would be ideal for a land yacht sail shape?
