We played a bit with a spin on our H20 this season. Started with the original spin which was cut way too big and launching from the tramp was no fun. We borrowed a Tiger spin and snuffer bag and had a ball with it. But the Tiger sail just isn't big enough. So we recut the big sail (ourselves) and tryed it with the snuffer. When we tryed it we went faster down wind than up!!! But suffice it to say we still have some tweeking. (tore out the gromit and couldn't use it to race) As crew I think that the H20 has a advantge with the spin because the jib is bigger than the F18. I work both and can get extra speed. Once you get a spin it is hard to go back. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> Have a blast!
