Thanks Rolf for your article on the Beachcats website. Because of you I have been playing around with the Sailcut program for some Hobie 18 sails. I measured my jib and have that designed. Starting to work on a squaretop for the mainsail. I still need a lot of dimensions to finish the mainsail. I don't have a cloth cutter but can plot out the panels on a large Cad plotter for the panel patterns. Keep up the information and discussion on sail design. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> I would like someone to critique my sail designs. I can be reached offline at djanddale at charter.net
