Main deck: The principal deck of a vessel; in some ships the highest deck of the hull, usually but not always the weather deck; in sailing warships often a deck under the upper deck. [3] Middle or waist deck: The upper deck amidships, the working area of the deck. Orlop deck: The deck or part of a deck where the cables are stowed, usually below ...
Replica of the Victoria, the only one of Ferdinand Magellan's five ships to return to Spain in 1522, showing both a forecastle (left) and quarterdeck (right).. The forecastle (/ ˈ f oʊ k s əl / ⓘ FOHK-səl; contracted as fo'c'sle or fo'c's'le) [1] [2] is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters.
The French definition of a three-decker differed from that of the English Navy until 1690, as some ships that were officially termed "three-deckers" prior to this date had only a partially-armed third tier of guns, with a significant gap between the guns in the forward portion of that deck and the guns in the aft portion of that deck. In some ...
Below: a lower deck of the ship. [1] Belowdecks: inside or into a ship, or down to a lower deck. [12] Bilge: the underwater part of a ship between the flat of the bottom and the vertical topsides [13] Bottom: the lowest part of the ship's hull. Bow: front of a ship (opposite of "stern") [1] Centerline or centreline: an imaginary, central line ...
A steel ship's hull may be considered a structural beam with the main deck forming the upper flange of a box girder and the keel forming the lower strength member. The main deck may act as a tension member when the ship is supported by a single wave amidships, or as a compression member when the ship is supported between waves forward and aft. [2]
Early in the 20th century, a new design was becoming prevalent on Great Lakes ore/ bulk cargo freighters. [1] Instead of locating the pilothouse and deckhouses in the center of the ship, the new design placed deck houses at the extreme front and back of the boat. The name "straight deck" referred to the large flat cargo hold expanse in between.
Ships in that size range can carry between 2.5 million and 3.5 million gallons of fuel. The amount of fuel actually be used on a sailing depends primarily on the ship's speed.
The sheer is a measure of longitudinal main deck curvature in naval architecture. The sheer forward is usually twice that aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship.
