I've had my hull planing on many waves, in the wake of cargoships. While the hullspeed of my kayak is about 9 km/h, I've read a topspeed of 18 km/h on my GPS on some occasions. Probably I've gone faster, but every time I made the "surf of my life" I hadn't bother to turn on the GPS. I hope this does not lead to another debate on what actually constitutes planing. There are somewhat credible reports of baidarkas hitting (or possibly exceeding) 10 kts. That is more than their theoretical hull speed. I do not remember whether it was a PW contributor who previously pointed out that the standard multiplier of 1.34 used in determining theoretical (!) hull speed of ships (naval destroyers) has to be adjusted before applying the formula to longer, more slender hull shapes (kayaks, multihulls, etc.).
