Urban Boatbuilders is a youth development agency serving at-risk kids in the Twin Cities area. We build wood canoes and boats. We were given an unusual boat. We really don't know much about it. It is a trimaran, which we've had on the water a time or two. We were told that it can be converted to become an iceboat or a skiboat. To me it really looks like two boats that might share masts and sails. It is interesting and a bit of a puzzler. I'll try to attach a picture of it as a trimaran and a picture that shows some of its iceboatiness. We have a room full of other equipment for it.
