Dean,
Most people don't buy a "pig in a poke". Your experience with the Rave is quite different than what I have observed on the Saint Lucy River. The Rave dealer that sold more Raves than any other dealer in the world use to demonstrate the boats on the Saint Lucy River in Stuart, Florida. I have watched them fail to become foil born many many more times than being successful in the effort. The problem was not lack of wind but too much 2ft to 3ft chop. The dealer has since moved on to other endeavors. The Rave foil boats have attempted the Miami to Key Largo Race many times....no success.
The swells in Barbados were 6ft to 8ft. With the foils 2ft under water and the hulls 2ft above the water, that requires at least 10ft tall legs and these numbers are not what you would call "big seas".
Team Philips thought they had tall enough legs holding their POD up above the hulls. But they found some seas that tore their POD off its legs and the boat was abandon.
Dean, 6ft legs are not going to cut it out in the real ocean even in a small storm or just 30 knot winds and normal waves.
