At least he wasn't aiming for a sailboat
When I lived and sailed in Miami and the Keys to many of these idiots wouldaim for my sailboat. I couldn't understand why until I noticed I was the only thing on the water that was relatively stationary and they could get a fix on.Many times they scared the heck out of me at how close and how fast they would zoom by. I guess they figured that if I was sailing then I was in deep water so they wouldn't run agound. Well, at least I'm glad he did it to a channel marker and not another (sail) boat!
