An excellent point. Aside from dragging there are all sorts of reasons you might need to get underway quickly in the middle of the night. And even if you are the "designated sailor", do you really want to have a bunch of drunk friends stumbling around while you're dealing with whatever the emergency is? Personally, I don't think alcohol on board is worth the trouble. Only safe place to drink on the water is tied up in your slip.
