I have one of the few 18 square Coyote catamarans. Recent posts about the squares motived me to try to chase down Chris Kilbourn who was the last person known to build one. I finally found him and he indicated that he has one and it is questionable if any more that exist other than his and mine. Contrary to earlier posts, the tooling still exists in Traverse City, Michigan and additional hulls could be built. I have yet to have mine long enough to assemble it but when I do I will post pictures.
