It is too bad that the system used for the Shark catamaran has not been adapted to others. It's a 20-foot-long, 10-foot-wide boat. It folds up in the middle so it looks kind of like a long teepee on the trailer. The folding and unfolding only takes a few minutes. I'm sure there must be some reason why it doesn't work for other boats, since no others have used it. The new Sharks weigh in at minimum weight of (I think) 450 lbs. Maybe the folding system only works because of the hard deck instead of trampoline? Oughta get Shark Builder John Rogers on here to comment. Always seemed to me like a better option than telescope or tilt.
