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]
Hurricane deck: (river steamers, etc.) the upper deck, usually a light deck, erected above the frame of the hull (deriving its name from the wind that always seemed to blow on the deck). [ 4 ] Lido deck : Open area, typically at or near the stern of a passenger ship, housing the main outdoor swimming pool and sunbathing area.
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.
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.
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]
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.
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]
First they had to gather material, so they went to the archives of the Star Trek: The Next Generation art department, where they found plans and drawings of the various sets created for the show. They also collected exterior drawings and photos to see how the ship had changed from its conception to its destruction in Star Trek Generations.
