Reminds me of when I was in the Navy stationed aboard a destroyer home ported in Charleston, South Carolina. Had to sail down the river to get to the sea, going under at least one bridge. First time we headed out to sea after being in port a while, we would give a hand crank to a new guy (there was always a few new guys on every voyage) and tell him to crank the mast down so we could go under the bridge. Hurry! we said, this is really important! Then we'd all watch and laugh as he ran all over the place trying to figure out where and how he was supposed to crank the mast down.
