I've seen a cat by the name of "Tyger Tyger" sailing in the Los Angeles region that has hinged beam for trailering. I think the boat is ~15-20 wide and about 25-30 ft long. It is not an ARC## or SC##...something totally different. The beams were hinged off centerline with tramp still basically attached to the hulls. I believe the owner's first name was Geoff Deutchmann. Wish I had more details on it...we raced against it in this years Newport to Ensenada run...we were on an F28R trimaran. He beat us.
