Hi, I new to this site so I messed up on reply yesterday. I don't go by 6014. I am using Dough Boy. As for your sail size, Go to sailboatspecifications.com and look up Shark Catamaran. I have never played around with sailing but am now working on a Shark. Everything seems to be great except the hull is two different colors and the wood needs redone. I'm thinking a second one would be nice for comparison or a Phoenix. They were designed and built by the same people.
