Hi all
The spitfire cat project along with Moth hold some design promise for future development and applications -
more info search BDG Marine. Home of the Spitfire 12.

note to Andinista
Sailing a high speed cat the skipper can luff into the wind to prevent capsize only when close hauled or close reaching ,-most other conditions when sailing with the wind aft of 70 degrees the skipper needs to bear off to prevent capsize . With a spin rigged cat with spin up --always bear away in gusts to prevent capsize while keeping speed .
- hope that is helpfull from a practical perspective ,

all the best
Carl
