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]
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.
Mid-Deck Tanker, damage up 3 m. Light gray is oil, dark gray is seawater. A Mid-Deck Tanker is a tanker design, which includes an additional deck intended to limit spills if the tanker is damaged. The extra deck is placed at about the middle of the draft of the ship. [citation needed]

Astern (adjective): toward the rear of a ship (opposite of "forward"). [9] Athwartships: toward the sides of a ship. [1] Aweather: toward the weather or windward side of a ship. [10] Aweigh: just clear of the sea floor, as with an anchor. [11] Below: a lower deck of the ship. [1] Belowdecks: inside or into a ship, or down to a lower deck. [12]
If you draw a box around the submerged part of the ship, it is the ratio of the box volume occupied by the ship. It gives a sense of how much of the block defined by the L WL, beam (B) & draft (T) is filled by the hull. Full forms such as oil tankers will have a high C b where fine shapes such as sailboats will have a low C b.
A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail-powered land vehicle.
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.
