Isn't it amazing what you stumble across when your looking for something totally different?
As far as I can make out, the current World Water Speed Record for a human powered boat is 18.5 knots, set in 1992 by MIT with their airscrew driven hydrofoil Decavitator.
Okay, Decavitator isn't a paddler, then I found this.....
So whose up for this one?
