e/Butt (sailing)

Information
has gloss	eng: In shipbuilding, a butt is the joint between two planks on the outside of a ship, under water. Hence, when a plank is loose at one end, sailors called it springing a butt; to prevent which, ships were usually bolted at the butt-heads, that is, at the plank's end.
