How many of these have common non-nautical uses? I don't think I ever use any of these terms, or hear anyone else use them, in common speech.
"tiller" is just the thing that controls the position of the rudder, which I think most people know about. (That said, nobody in aviation calls their rudder pedals the "tiller", so it might be a strictly nautical term.)
It's a good thing I'm not at the helm ;)
