Yep. And it's not just powerboats. I had to tack to avoid a same tack, windward sailboat on Labor Day on Lewisville Lake.

The more polite boaters around here tend to give way even when stand-on. That's nice of them, but they don't realize the stand on boat has a responsibility to behave predictably. And the rude boaters just assume everyone else will give way. The local authorities pretty much ignore it unless a collision occurs.
