Body Plan ----A drawing which shows frame lines in elevation. The body plan is made in two parts. The right-hand part is a view looking directly aft at the for'd port side of moulded surface, while the. left-hand part is a view looking directly forward at the after half of the port side. This arrangement prevents the frame lines at the after end from obliterating or fouling the frame lines at the forward end. This view shows buttocks and waterlines straight, while the frame lines appear in their true shape. Boiler ----Container in which water is heated to form steam. Boiler Chocks ----Stay braces which prevent fore and aft movement of boilers. More bilge blocks. Bilge ----A fore and aft member fitted to the outside of the shell plating along the bilge, to prevent excessive rolling of the ship. Bilge Pump ----Pump for removing bilge water. Bilge Strake ----Course of plates at the bilge. Bilge Water ----Water in ship due to leaks, sweat, etc. Boiler Foundation ----A support for a boiler. Bollard ----A single tie post (see bitt). Booby Hatch ----A watertight covering over a deck opening, which is used for a stairway or ladder. Boom ----A long, round, heavy spar, pivoted at one end, usually used for handling cargo, etc. E6002 – Ship Terms & Definitions p. 4 © C.G.Daley Here is a davit, or a cargo hose boom. This one design of several different types of devices designed to assist in lifting heavy items. The King Post or Sampson Post or Stanchion is the vertical pipe on the right side of the picture. The boom (spar) extends to the left, and is supported by a boom rest near the tip, and the boom socket (step) at the base of the king post. Boom Rest ----A support for a boom when the boom is not in use. Boom Step ----A socket for end of boom. Bosom Piece ----A short piece of angle riveted over a butt joint of two angles, a butt strap for angle bars; a splice piece. Boss ----The curved swelling portion of the ship's hull around the propeller shaft. Propeller on a river towboat. This one has 4 blades and is designed for power rather than speed. 4 blade propellers have less vibration than 2 or 3 blade propellers, benefiting the crew. Boss Frame ----A hull frame which is bent for clearing propeller shaft tube boss Boss Plate ----A shell plate covering the curved portion of hull where the propeller shaft passes outboard. Bow ----The forward end of a vessel. (Usually the pointed end.) Here is the bow of a tank barge on drydock. Propeller on a ferry. Most US ferry's have identical propellers on both ends. This way they do not have to back up to get into the slip, making it much easier for the vehicles to drive on and off. The boss and the oxter plate is here somewhere. Bowsprit --A spar projecting forward from the bow of a vessel used to attach sails and stays. Bracket ----A triangular plate used to connect rigidly two or more parts, such as a deck beam to a frame, a frame to a margin plate, etc. Braze ----To heat and join by means of hard solder (spelter). This may be brass, bronze, or other alloys. Breakwater ----A braced guard plate which prevents solid water from sweeping the decks. E6002 – Ship Terms & Definitions p. 5 © C.G.Daley Breast Cap ----Small plate on top of bulwark, at stem of vessel to stiffen bulwark. Bunker ----A compartment used for the stowage of coal or other fuel. Breast Hook ----A triangular-shaped plate extending horizontally across the bow behind the stem, stiffening the stringers and stem. Buoyancy ----Ability to float; lifting power when immersed. Bridge, Navigating ----A deck from which the ship is navigated. Bridge Deck ----A deck of the superstructure amidships. Brow ----A watershed over an airport; a small inclined runway to allow passage of trucks over hatch coaming, or through bulkhead door, etc.; sometimes portable. Buck frame ----In a double skin tank barge, these frames act as spacers in the void tanks. A 4'6" wide void might have 2 vertical 8" channel iron with 3" x 3" x 5/16" angle iron between. Also called a transverse truss. Building Slip ----A place where the ship is built; a shipway. Bulb Angle ----An angle shape, which is reinforced at one toe. Bulb Plate ----A narrow plate reinforced on one edge. Bulb Tee ----A Tee bar with toe of web reinforced. Bulkhead ----A vertical partition corresponding to the wall of a room, extending either athwartships or fore and aft. A steel partition in a ship. The vertical partitions that divide the hull into separate compartments are called bulkheads. Some are watertight. These watertight bulkheads are so arranged that in case of accident at sea, water would be confined to one compartment only. The collision bulkhead in the front end is constructed to withstand heavy strain and shock in case the bow be staved in. Bulkhead Sluice ----A small opening in a watertight bulkhead which can be opened or closed from the deck above. Bu...
