I wrote a nautical vocabulary question ELU, and then realized that people with practical experience about boating might be able to answer it better over on Great Outdoors. I got the answer I needed there (in a comment to the answer, actually). I think this means I should delete the question here. Is that right?
I would be okay with leaving both, and posting links at each to the other, but I'm afraid I may get in trouble at some point, so I'm asking now, before I get in trouble.
(The other question got closed, by the way. But the responses I got there were more useful than the ones I've gotten here, so my preference would to keep the one there.)
