I keep waiting for someone to answer your post, but it seems everone that has a 18 square doesn't want to part with it. I have a Coyote 18 square which is an even more limited version. It has light kevlar/fiberglass hulls and a curved traveller track. I really wasn't looking to sell it, but I have four catamarans and I can only sail one at a time. The boat is located in SW Michigan. If you are interested call me a 574 271-2700 x201 or email me.
