My ideal beach cat already exists. It sits on a trailer a few miles south of me and gets broken out for the big regattas.

It is the G-Force 21 Grand Prix. 21' long and 11' wide with high-volume hulls and a really tall mast (owner has installed a mast taller than what the Tornados are running). It's got a nice new square-top main and roller-furling jib. I think a roller-furling reacher would be the perfect headsail for this boat in the common conditions for my area (fairly light winds in the summer). I would like to see a set of "wings" on it and 3 trapeze wires per side. A deck configuration that loses the deck-lip and increases bow volume would be nice, and is exactly what Hans did with the new G-Cat 5.0 Turbo.

Otherwise... I'd like to see a kevlar or carbon-fiber version of the Reynolds 21 Cat. Something like an 'expedition' boat that can hold some gear, get the crew out of the weather, and handle rough conditions. It should be light enough (when empty, at least) to be cat-tracked up the beach by two people.
