Bilge compartment in a steel hulled ship (looking down) Bilge compartment and pump. The bilge / b ɪ l dʒ / of a ship or boat is the part of the hull that would rest on the ground if the vessel were unsupported by water. The "turn of the bilge" is the transition from the bottom of a hull to the sides of a hull.
Colourised engraving of a French galley (27 pairs of oars) built according to the design that was standard in the Mediterranean from the early 17th century; Henri Sbonski de Passebon, 1690. A galley is a type of ship optimised for propulsion by oars. Galleys were historically used for warfare, trade, and piracy mostly in the seas surrounding ...
The ship that would be known as Queen Anne's Revenge was a 200-ton vessel believed to have been built in 1710. She was handed over to René Duguay-Trouin and employed in his service for some time before being converted into a slave ship, then operated by the leading slave trader René Montaudin of Nantes, until sold in 1713 in Peru or Chile.
The keel runs along the centerline of the ship, from the bow to the stern. The keel is often the first part of a ship's hull to be constructed, and laying the keel, or placing the keel in the cradle where the ship will be built, may mark the start time of its construction. Large, modern ships are now often built in a series of pre-fabricated ...
Volume (V or ∇) is the volume of water displaced by the hull. The volume of a ship's hull below the waterline (solid), divided by the volume of a rectangular solid (lines) of the same length, height and width, determine a ship's block coefficient. Coefficients [5] help compare hull forms as well:
It was an official, though rare, punishment in the Dutch navy, [15] as shown in the painting The keelhauling of the ship's surgeon of Admiral Jan van Nes. This shows a large crowd gathered to watch the event, as though it was a "show" punishment intended to frighten other potential offenders, as was flogging round the fleet.
It was used in British anti-torpedo-system design practice in its last battleships. The internal hull and torpedo bulkheads and internal decks were made of Ducol or "D"-class steel, an extra-strong form of HTS. According to Nathan Okun, the King George V-class battleships had the simplest armour arrangement of all post-WWI capital ships. "Most ...
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
