Good on ya! Beer is serious stuff -- at least good beer is.Well we live dangerously then as there are well over a dozen breweries within a half hour drive of our farm (lots of good water here), Heck I've included what we have in our basement...yup, we are serious about the art of fermentation!
I've seen this issue pop up online a few times. It's interesting because in Canada it is perfectly legal to drink on a cruising-level boat* while it is anchored. It is considered being "affixed to ground", just like being moored or tied to the dock. So you are not underway -- at least not in Canada.FWIW...there had been discussion here about not having drinks when underway but ok when at anchor. I personally have not heard of any issues with such, at least with the folks we know, but technically you are still underway when at anchor (just not making way) and thus subject to USCC reg's on such. Never stopped us once ground tackle is in place, but we also remain aware we may need to "drive" again!
I've heard that in the USA this legal definition varies from state to state, but I've not really looked into it.
*There is a legal definition of a "cruising level boat" (which is my term, not the legal term). As I recall it includes having a proper galley, head and maybe sleeping berths. I'm sure some legal beagle can dig it up if need be.
