The situation in your article isn't one that I can relate to.

For one thing, they weren't "sailors", they were in stationary boats.

from the article "It's probably not realistic to expect that the owners
of these secured and stationary boats will refrain from enjoying a few
beers, a little wine, or a couple of cocktails with friends and family
that may be aboard, but even this situation can get as mixed up as a
Margarita. If the visitors need to be taken to shore in a dinghy the
skipper needs to be sober."

I've never heard of a sailboater out on the water being busted for
alcohol. As soon as you say something like that, it'll happen. For
example, I never heard of a sail boat being busted for out of date
registration in the middle of a regatta and someone told me that it
recently happened on my lake.
