Hi Gary, as Jake put it "we have work to do .."
Fastest cat recorded over a 500m course was, I believe, a Tornado, at 23 knots (at least what I can gather from a previous thread on the subject.) These guys are running down the trench at double that speed.

Wow, that is some claim to fame, to have sailed a speed trials against Fred Haywood. He held the record for windsurfers at 32.86 knots, in 1986 I think. (Funny, I remember the speed, not the year, must be getting on.) That was when they said it would be impossible to break Crossbow 2`s record of 36 knots. Now all the serious efforts are in the 44 knot range !!

Time to dust off your old speedboard, then

Steve
