It can get scary.
The biggest problem that I have had from power boat wakes with the H23 is when taking one (or should I say receiving one) aft of the beam. Forward of the beam, as well as right on the beam, the boat seems to be very easy to control and recover. The few times that I've been hit by wakes aft of the beam but not on the stern, the H23 just seems to lose it. It was never close to capsizing. It just really rocked and rolled in ways I can't explain. The worst times seem to be when the wakes comes from the port side-aft. That's also where much of the weight is centered on the "stock" H23's (motor, battery, water, etc.) so I wonder if that has something to do with it.Just hang in there and enjoy the boat! The first year I had the H23, I barely was able to get out of the harbor (it is a large one) since I had to spend so much time trying to dodge / tack through powerboat wakes.
