The only powerboaters that really bother me are the inconsiderate ones. Inconsideration is a lot like pornography....I can't define it for you, but I sure as heck know it when I see it.
Inconsideration gets me. So does ignorance, but now quite as much. I don't excuse ignorance, because my attitude is that if you're going to share the waterways with me, you need to educate yourself so you're a participant and not a contaminant.
The powerboat attitude often comes through in the name of the boat. I've seen "Bad Attitude", "Intimidator", "Avenger", "Bad Boy IV", etc. What's up with that?
If you've chosen to own and operate a vessel that throws a wake, be responsible for it.
