It is the lowest deck in a ship. [6] Poop deck: The deck forming the roof of a poop or poop cabin, built on the upper deck and extending from the mizzenmast aft. Promenade deck: A "wrap-around porch" found on passenger ships and riverboats encircling the superstructure. This can have open railings or be enclosed in glass, or a combination.
Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...
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.
On container ships the position of containers are identified by a bay-row-tier coordinate system. The bays illustrate the cross sections of the ship and are numbered from bow to stern. The rows run the length of the ship and are numbered from the middle of the ship outwards, even numbers on the port side and odd numbers on the starboard side ...
Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
Dimensions of a hull The prominent sheer in the bow of the battleship USS New Jersey View of a corridor on the RMS Queen Mary, visibly showing the sheer. Notice the upward curve as the corridor goes on. The sheer is a measure of longitudinal main deck curvature in naval architecture. The sheer forward is usually twice that aft.
Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion measured relative to the ship's load line , regardless of deck arrangements, is the mandated and regulated meaning.
