Ya know- this is really quite a funny post. Have you noticed that some of you mention mph ( mile per hour ) and others mention kts ( knots ) and that there is considerable difference between the two?

I have little doubt that some beach cats have managed to hit 30mph, but I find it difficult to believe they've reached 30kts.

And powerboats, especially big racing ones, tend to be calibrated in MPH so the average spectator can accurately understand and compare the speeds involved.

Here's a question for you- at what speed does the Hobie Trifoiler cavitate and come down off the foils? Is it in the 40mph range, or 40kts range?
