Hi Guys,
Have to agree with Red Rocket. There is little point in writing it up on a forum apart from alerting others to these guys. The best action is to approach them on the beach or on the water.
If you are afraid of a negetive backlash from the perp, your correct, you'll probably get one, but if you show a little tact at least you'll get your message across. It'd make you feel marginally better after blanket bans are imposed on your fave break that at least you did the right thing and were not idly sitting by, shaking your head in disapproval, doing nothing and watching the action that causes the ban to be implemented.
We regularly approach people on our beach and let them know that dangerous actions are not appreciated at our spot. We don't seem to have too many problems and usually the ones that do arc up don't come back.

Good winds,
