48 inch wing sail cat wins Round the Island race in record time

Graham Herbert, local IOM champion sailor, showed up for the Round Protection Island annual race with his AC style 48 inch wing sail cat to win in a new course record time. This race is over 3.5 miles around Protection Island, off Nanaimo harbour in British Columbia. The previous record was 1hr 15 min held by an IOM. Graham shattered the record finishing the course in 49 minutes.

Graham's boat uses three channels - rudder, sail sheet, and wing camber. The sail self tacks and the camber is controllable, but the twist is preset onshore. The A rig has a three section wing mast made of thin carbon fibre and is hinged at 50%. Everything is scratch built.

The video is a bit jerky for the first few seconds due to the chop and the small camera boat, but stay with it.

Fang 5 (1 min 32 sec)

Really the best performing RC cat I've seen so far!
Any chance of having some more data or even maybe the plans for sale?

Would almost think of trying a very light weight bungee as a "Leech Line" - holding the trailing edges in line with light wind, but soft enough to allow the three main sections of the wing leech to be "blown open" as wind increases. This might improve the performance by allowing the twist to be adjusted by the wind instead of fixed position - or trying to sail and adjust trim by another channel.

Just a thought.
