No, that's not what he said, and that's not what I quoted. You are expanding his quote (that I responded to) into something more to make your point.
This is what he said...
"I believe I prefer individuals who drink while boating to the drinking/drunken owner jerks who populate the marinas and docks. As a live aboard, one gets a very interesting perspective and insight into the boating community at large....largely alcoholics it seems. As a matter of fact, as I started typing this a well known drunk who frequents the marina on his boat stopped directly in front of another boat that pulled in next to us. The boat has a pennant that says "Happy Hour"....one of the universal signals amongst the serious drinking crowd. What this means for us is that the drunk and his wife will invite himself aboard the transient and they will disturb our peace for the rest of the evening. Since it's a sundeck boat, they will likely gather there as opposed to setting up the more typical drunk camp on the dock. This same sub-culture is very evident in the looper community. Anyway, I have to wonder how long it takes to metabolize a snoot full as many of these folks take off bright and early after a night of imbibing. Doubt they get eight hours between bottle and throttle."
He did not indicate any of the things you mentioned.
You can infer all you want, and so can I, but we need to get the facts straight.
My interpenetration of his quote is that someone met a friend at the dock as they were tying up. He was worried that they might sit out on their sun deck relaxing, and by doing that they might disturb him.
The reality of dockside life (for the large boat docks at least) isnt that they/we are a bunch of kids turning up the stereo. (remember you might be young, but for the most part big boat owners take decades to be able to afford their boats) They're older people, meeting a few friends on their tied up boats for a cocktail. Generally we're talking about no more than 6 people.
We need to remember that a dock is a shared space. I have not seen (again on the large boat docks) anything more than some older people socializing. If that pisses off someone that chooses to make that shared space their home, well sorry. Its a shared space.
There is no more right on a dock to get upset by some people socializing than would be appropriate to be upset at someone like the charter captain parked next to me that cleans his the exterior of his boat at night, and has people standing next to my porthole where I'm sleeping at 4:00 am boarding for a days fishing.
Its a shared space. If we want absolute quiet, the harbor isn't the place to be.
