I picked up an older A-cat last month it's an Auscat built and designed by Boyer and Goodall in Australia.

The Mast is hollow carbon fiber at 30' the hulls are a mix of honey comb, kevlar, carbon and the sail 150 sq ft. has so many carbon strips it looks gray from a distance. The whole boat weighs 165 although it won't fit on my scale thats what it feals like. I can single hand it on and off the water. Starting sailing it Nov. 1st 2008 after 3 weeks restoring a few things.
Here's what they can do with a pro, Glenn is the current world Champ.
