boom

The Sailor's Word-Book

A long spar run out from different places in the ship, to extend or boom out the foot of a particular sail; as, jib-boom, flying jib-boom, studding-sail booms, driver or spanker boom, ringtail-boom, main-boom, square-sail boom, &c. A ship is said to come booming forwards when she comes with all the sail she can make. Boom also denotes a cable stretched athwart the mouth of a river or harbour, with yards, top-masts, or stout spars of wood lashed to it, to prevent the entrance of an enemy.


♦ To top one's boom, is to start off.

♦ To boom off, to shove a boat or vessel away with spars.
