Re: Mr. Annoying Drunk guy doesn't get the hint that I don't want him on my boat anym
Look there are a lot of issues here.
The first one is you get to decide who goes on your boat, and what happens on your boat. Its not just because its your property, it is because you are responsible for the safety of you, your guests and what happens with your boat. If a guest, won't, or can't, behave in a safe manner, then keep him/her off your boat. No explanation needed.
There is another issue, and its a big one. It sounds like your friend is an alcoholic. I know you said it, but based on your actions it does not sound like you believe it, or you don't understand what is going on. Here's the thing; alcoholics when they drinking care about one thing, and one thing only - the next drink. They will not listen to logic, or reason. They certainly won't listen to your boat safety rules. They also won't stop until they decide to stop. Loss of careers, marriages, friendships, even their own health is not enough until they decide its enough. So as long as he is drinking he is not going to be anyone's best boating companion. All you can do is tell him you don't want him around while he is drinking and hope he decides to attend a meeting and get himself cleaned up.
