DIY kayak Build I havent started the wingsail other than the patterns for the wings to date, just trying to get everything built for the trimaran for New Years day regatta. I acquired a 1967 sunfish and its rig last night, so the rig will go on the boat until the wing is built and tested.
Jake, bungee may be the easiest way to go, thanks, didnt even think of it, and I have used alot of bungee on rotators in my life...
