I thought a windsurfer had set the sailing speed record at about 49 mph in the French Trench? Or was that the Slingshot sailboat before it blew up?

I had talked to a designer several years ago about the theoretical top speed of an open 60 trimaran. He said based on sail area, displacement and drag numbers the top speed should be about 40-50 mph but the sea state won't allow it, they need about 30+ knots of wind and flat seas to do it. That just doesn't happen.

But in that video the trimaran is obviously limping along at half speed with a reefed main and on two hulls, not their prefered go-fast set up. I'm sure they could have easily passed the windsurfer if they had wanted to.
