wow thanks for all the responses.... first off for everyone freaking out about the 18sq.... I have NO intention of breaking up my boat. I love the square. If I do this project I will have an either-or arrangement. My reasoning for the interest in the tri is more of a multi-person fast party barge. I often have 2 or 3 tag-alongs when i go sailing and the sq sucks above single-handed. To be honest I'd love to rig a tornado, but cant really afford to have two fully rigged boats. so to all interested in the sq make me an offer. send me a pm and i'll give you all the details of the boat. but anyway.. heres a pic of the sq.
