There are a number of "problems" in the smaller cats. One of which is that the wide beam is what gives the sailing cat stability--if you bring it down to 8.5 feet or even 10 feet, without movable ballast (which Hobbie and other small cats depend upon--the crew)--it will not be stable enough to be reliable. I have a friend who built an ultra light cat motor sailor, with about 10 foot beam and 33 feet length. It went in the water at just over 1200 lbs, and uses a 14 hp engine to go about 10 to 12 knots. Sails about the same speed in the right conditions, with a Prindel 16 rig and larger genoa. But it is relitatively tender, and has minimal accomidations. (There is a pod with sitting head room on the bridge deck, you can sort of stand in each hull under this pod, but not straight up). I am not sure if the current owner would sell it or not. The cost of building was high, because of the use of exotics and the extensive engineering which went into the boat. There were several production cats--the Stiletto 27 & 30 and the McGreagor 36 which are both trailerable and will power at a brisk pace. I believe that both of these had folding or take down bridge decks to get the beam down to trailering. (not sure of the 27 beam, but the 30's beam is about 18 feet when up). The McGreagor is 18 foot beam when assembled. Many of these have the bridge deck fixed in place and are kept at the max beam. Neither of these boats have what I would call true cruising accomidations, but we have seen both of them cruising--including a McGreagor 36 going down the coast of Mexico to the canal. Remember that these boats can capsize! If you want more accomidations and a multihull consider the Corsair Marine Trimaran series--I believe that they go from 24 at the low end to a 37 footer with 9'6" beam at the high end--all trailerable, with considerable room in the hull and a good turn of speed under power if you need to. I have sailed several of these and they are very well behavied. In fact if I was to go back to sailing, I would buy a Corsair Marine Tri. Bob Austin
