Dear Seeker,
If I may interject before Bill posts his answer…… (and the answer may just simply come down to weight). In WWII, the Japanese had a “Catamaran” that was launched from a Submarine. The Sub(s) (they built 3 of them with intentions of attack the Panama Canal very late in the war….) was one of the largest Subs ever built until the US built one larger in the late 1960’s during the Cold War. I say it was a Catamaran… But really it was a Sea Plane with two pontoons or floats…. There is your Catamaran that folds!

The interesting thing was the complexity of the winds, they were fully articulating. They didn’t just fold up….. They folded up and then folded back inline with the fuselage for storage. Very High Tech for 1945.

The question I have for Bill (or would like to add)….. Has anyone attempted to race, sail, and survive….. on an 8 ½ foot wide ARC22 or SC20TR. With all of these race organizers putting limits on beam width – Did you ever slim one down and try it out???
