Spirit of Catalina

Bob Quinton of Suffolk (England) with "Spirit of Catalina", a catamaran with an over-the-top wingsail. (i.e. it is flipped over the top to tack - it is upright while sailing).

The sail is called "Skean-Dhu" (Patent No 9109807.9), and it controls an asymmetric underwater hydrofoil, to counteract the side force.

Bob sails with no wet-weather clothes (apart from boots for launching) and returns perfectly dry - in a collar and tie.

Bob died in 2004. Any enquiries to Gen Quinton See their web page on http://www.boatek.club24.co.uk
