Aiming for you - give me a break. You can think what you want about boaters, but the number of people who would intentially try and kill a diver, as you suggest, would be miniscule. Most boaters are ignorant to what a dive flag is, and that is nothing but our lousy education and lack of enforcement.
To suggest that boaters would actually try and kill a diver is insane. Sorry - but I have a little more faith in human beings than that.
As a boater and a diver, I know all too well the question - "Hey, what does that flag mean?". Add that to tiny little flags in choppy lakes that can't be seen by those who do know, and no fines for those who don't care to stay far enough away, and there is your problem.
I agree - much better public education and enforcement with stiff fines. Lord knows the Police on Simcoe just love handing out tickets!!
