I think you missed my point....I'm fairly confident that most of the posters on here may at some time have driven a boat after a lunchtime pint or two (myself included) but at the same time excercise reasonable self control and
judgement as to what is sensible.
For example, drinking enough to have twice the legal blood alcohol level and then going out for a night-time 40knot blast is very much in the NOT sensible camp, and precisely the type of behaviour likely to increase the chances of draconian legislation being brought to bear against the whole of the sailing/motoring/PWC community.
However the type of person prone to this type of behaviour is also the same type of person prone to ignoring the very legislation designed to prevent it.
These people will continue to buy powerfull boats and take them out without experience or training or consideration for other water users etc etc etc.
Meanwhile the VAST majority of British law abiding boat users will be saddled with increased costs and regulations that they neither asked for or deserve.
Legislation is not the answer...education most definately is.
