I made a facetious retort in another thread about drinking and boating, but it made me curious about other skipper's habits.
I enjoy a malty or rum-based beverage as much as the next person, but I made a resolution to restrict my imbibing to the dock or the anchor (when I wasn't on watch, that is). I'm not ultra-strict about it, but if I have a can of beer when underway it must be a stinking hot day. I don't drive, but basically I treat the boat as if I was driving, and therefore don't drink alcohol when in motion.
I started this before the water cops started giving people breathalyzers on the water. It was a personal, not a regulatory or "spoilsport" decision. As for crew, I expect one other person to stay cold sober. If there are guests, I don't care if they get completely faced, but I reserve the right to clip them in, restrict them to a bucket, or keel haul 'em if they get boisterous.
What are the views of those here? Abstainer, moderate drinker or "hell, the thing only goes five knots..." (I've seen the entire spectrum, including the delightful sight of wasted rail meat hurling down the topsides at the start line...)
