Sorry to hear that, Skunk. Those idiots should know better. In order to be operating a boat of that power on non-tidal waters they would require a boat license. In order to get a boat license, they also need the boat safety certificate. The certificate is only granted after taking an approved class and passing an exam. The safety and navigation lessons in the class I took were very helpful. You should call the police if you can get the hull registration number, as it sounds like these yahoos were doing everything wrong.
