Bank (sea floor):nA large area of elevated sea floor.
Banyan: Traditional Royal Navy term for a day or shorter period of rest and relaxation.
Bar: Large mass of sand or earth, formed by the surge of the sea. They are mostly found at the entrances of great rivers or havens, and often render navigation extremely dangerous, but confer tranquility once inside. See also: Touch and go, grounding. Alfred Lord Tennyson's poem 'Crossing the bar' an allegory for death.
Barrelman: A sailor that was stationed in the crow's nest.
Bar pilot: A bar pilot guides ships over the dangerous sandbars at the mouth of rivers and bays.

Beam: The beam of a ship is its width at the widest point, or a point alongside the ship at the mid-point of its length.
Beam ends: The sides of a ship. "On her beam ends" may mean the vessel is literally on her side and possibly about to capsize; more often, the phrase means the vessel is listing 45 degrees or more.

Bear down: Turn away from the wind, often with reference to a transit.
Bearing: The horizontal direction of a line of sight between two objects on the surface of the earth.
Before the mast: Literally, the area of a ship before the foremast (the forecastle). Most often used to describe men whose living quarters are located here, officers being housed behind (abaft) the mast and enlisted men before the mast. This was because the midships area where the officers were berthed is more stable, being closer to the center of gravity, and thus more comfortable. It is less subject to the up and down movement resulting from the ship's pitching.
Belaying pins: Bars of iron or hard wood to which running rigging may be secured, or belayed.
Berth A bed on a boat, or a space in a port or harbour where a vessel can be tied up.
Best bower (anchor): The larger of two anchors carried in the bow; so named as it was the last, best hope.

Bimmy: A punitive instrument.
Binnacle: The stand on which the ship's compass is mounted.
Binnacle list: A ship's sick list. The list of men unable to report for duty was given to the officer or mate of the watch by the ship's surgeon. The list was kept at the binnacle.
Bitt, plural Bitts: Posts mounted on the ship's bow, merely comprising two wooden uprights supporting a crossbar, for fastening ropes or cables; also used on various ships to tie boys over for painful (posterior) discipline, more informally than kissing the gunner's daughter.

Booby: A type of bird that has little fear and therefore is particularly easy to catch, hence booby prize.
Booby hatch: A sliding hatch or cover.
Boom: A spar used to extend the foot of a for-and-aft sail.
Booms: Masts or yards, lying on board in reserve.
Boom vang (vang): A sail control that lets one apply downward tension on the boom, countering the upward tension provided by the mainsail. The boom vang adds an element of control to mainsail shape when the mainsheet is let out enough that it no longer pulls the boom down. Boom vang tension helps control leech twist, a primary component of sail power.
Bottomry: Pledging a ship as security in a financial transaction.
Buoy: A floating object of defined shape and color, which is anchored at a given position and serves as an aid to navigation.
Bow: The front of a ship.

Bowline: A type of knot, producing a strong loop of a fixed size, topologically similar to a sheet bend. Also a rope attached to the side of a sail to pull it towards the bow (for keeping the windward edge of the sail steady).
Bowse: To pull or hoist.
Bowsprit: A spar projecting from the bow used as an anchor for the forestay and other rigging.
Brail: To furl or truss a sail by pulling it in towards the mast, or the ropes used to do so.
Brass monkeys or brass monkey weather: Very cold weather, origin from the cannon balls being stored on a wheeled platform (monkey) made of brass. If the weather was so cold as to cause cannon balls to fall off the brass monkey due to different shrinkage rates of the dissimilar metals it was termed to be cold enough to freeze the balls off a brass monkey.

Bring to: Cause a ship to be stationary by arranging the sails.
