Valid points but how do you change the way people behave short of a 2X4 across the head to get their attention? From what I see it is not excessive speed or the size of a boat but a lack of consideration for the other person. Its the you first AFTER me mentality that seems to prevail.
I don't know how many times we have had to slow down while towing a skier or wake boarder to allow someone to cut across in front of us or were sitting picking up a fallen skier only to have a boat fly by with in the 150' limit.
How about mounting 50 calibers on the bow and allowing warning shots across the bow of a vessle that does not obey the rules? Of coarse, only rubber bullets will be allowed.
