Im sure that there are many cases of ignorance. Most all places i go to that has motored traffic require some sort of license or permit requirement to drive a boat or has postings of divers flags and the associated legal backing. Notices such as,,,,,,driving a boat while under the influence is a crime exist quite often with notices to stay clear of divers flags by 50yd ect are often posted or briefed at many water way entrances. I have ;many times been topside to waive off boaters who get too close to flags. jet skies enter coves and approach with 10 ft of flags or bubbles they find surfacing as they race by.
