Yes, Marstrom 20 with snail spin set up and also notice the curved dagger boards. Too bad they broke a small rudder part that kept the rudder locked down. It broke while they were launching it. They tried to fix it but it did not hold.
There were two Marstrom 20's. One with straight dagger boards and one with curved. Would have been interesting to see who would win this long race. The Curved dagger board boat won Miami-Key Largo but they took different routes at the end that made the difference.
