Really?

I don't think there is any rationale for picking up a vacant mooring, primarily because I wouldn't know what was at the bottom of it or when it was last serviced. Not to mention that the owner might be back to tie up. I prefer to anchor unless I am asked or authorized by the owner, who can tell me something about the ground tackle and service history. NFW do I want to be on an unknown mooring when the wind shifts and blows up in the middle of the night. Done that...
