I have encountered this term before, but couldn't recall it. It was the screened-out word in today's Dictionary Devil puzzle.

bitt /BIT/ - 1. a post or pair of posts fixed on the deck of a ship for securing lines  2. bollard 1

I've probably encountered this term in my limited nautical experiences. It's interesting that the definitions for bitt and bollard refer to each other. Apparently the names of the ship-mounted and wharf-mounted devices are misused for each other commonly enough that each has become acceptable for the other.
