You asked "So the problems the children's camps are having is what... A lie? Unimportant?"
My response is
H**L No!!!
So far as I'm concerned,
any operator of
any type of boat that recklessly endangers a child, in whatever way, deserves no mercy.

At a minimum, confiscate his boat and take away his privilege to operate a boat in NH forever. Tar and feathers might be good, too.

You knock 'em down and I'll stomp on 'em! My suggestions for dealing with someone that actually harms a child can't be printed in a family-oriented forum.
But, as I've said all along, to get my buy-in you need to go after the specific bone heads that are doing the endangering rather than punishing the many for the sins of the few.
I also feel that Camp Directors need to exercise due dilligence in protecting their campers, though. For instance, on swims that go outside marked areas there need to be plenty of highly visible safety boats, and I wouldn't let a kid get more than a few feet from shore in a canoe - period. (IMHO, the darned things are death traps.

Stock up on decent kayaks for paddle sports, and tradition be danged.

)
I'll let you in on a well kept secret. I personally do not oppose the idea of a speed limit per se. But I vehemently oppose implementing one that is specifically designed to drive a particular type of boat off the lake because some folks disapprove of that type of boat.
