Surprising! I have to admit I have been in powerboats a couple of times and, in my memory, I was able to throttle down the engine once the boat was planing. That only shows that memory and observation can be deceptive: I have no doubt that Matt has the correct data. Niels and Matt, I too have experienced this feeling, but what I expect is really happening is that you (and I) have had the throttles wide open to get up on a plane and are still accelerating as we move up the bow wave and through the transition to planing. After we get up on the plane we throttled back to a constant velocity, rather then continuing to accelerate at an even faster rate.
