The main deck of a ship is the uppermost complete deck extending from bow to stern. [1] 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]

Boat vessel for transport by water

A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size, shape, cargo or passenger capacity, or its ability to carry boats.

Hull (watercraft) Watertight buoyant body of a ship or boat

A hull is the watertight body of a ship or boat. The hull may open at the top, or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.

Wireless telegraphy Method of communication

Wireless telegraphy or radiotelegraphy is transmission of telegraph signals by radio waves. Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires, such as electromagnetic induction, and ground conduction telegraph systems.

USS <i>Colorado</i> (BB-45) Colorado-class battleship

USS Colorado (BB-45) was a battleship of the United States Navy that was in service from 1923 to 1947. She was the lead ship of the Colorado class of battleships. Her keel was laid down on 29 May 1919, by the New York Shipbuilding Corporation. She was launched on 22 March 1921, and commissioned on 30 August 1923. She was armed with eight 16-inch (406 mm) guns and fourteen 5-inch (127 mm) deck guns; two 5-inch guns were removed in an overhaul.

USS <i>Franklin</i> (CV-13) US Navy Essex-class aircraft carrier

USS Franklin, nicknamed "Big Ben," was one of 24 Essex-class aircraft carriers built during World War II for the United States Navy, and the fifth US Navy ship to bear the name. Commissioned in January 1944, she served in several campaigns in the Pacific War, earning four battle stars. She was badly damaged by a Japanese air attack in March 1945, with the loss of over 800 of her crew, becoming the most heavily damaged United States aircraft carrier to survive the war. Movie footage of the actual attack was included in the 1949 film Task Force starring Gary Cooper.

Striking the colors To haul down a flag to indicate surrender

Striking the colors—meaning lowering the flag that signifies a ship's or garrison's allegiance—is a universally recognized indication of surrender, particularly for ships at sea. For a ship, surrender is dated from the time the ensign is struck.

Deck (ship) Part of a ship or boat

A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names.

Top (sailing ship) Platform at the upper end of a mast on a traditional square rigged ship

The top on a traditional square rigged ship, is the platform at the upper end of each (lower) mast. This is not the masthead "crow's nest" of the popular imagination – above the mainmast is the main-topmast, main-topgallant-mast and main-royal-mast, so that the top is actually about 1/4 to 1/3 of the way up the mast as a whole.

Gun deck

The term gun deck used to refer to a deck aboard a ship that was primarily used for the mounting of cannon to be fired in broadsides. The term is generally applied to decks enclosed under a roof; smaller and unrated vessels carried their guns on the upper deck, forecastle and quarterdeck, and these were not described as gun decks.

Linkspan

A linkspan or link-span is a type of drawbridge used mainly in the operation of moving vehicles on and off a RO-RO vessel or ferry, particularly to allow for tidal changes in water level.

Stern Back or aft-most part of a ship or boat

The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite the bow, the foremost part of a ship. Originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a white navigation light at night.

<i>Mayflower</i> Famous ship of the 17th century

Mayflower was an English ship that transported a group of English families known today as the Pilgrims from England to the New World in 1620.

<i>Titanic II</i> (film) 2010 film by Shane Van Dyke

Titanic II is a 2010 drama disaster film written, directed by and starring Shane Van Dyke and distributed by The Asylum.

Compartment (ship) Portion of the space within a ship

A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged. Subdivision of a ship's hull into watertight compartments is called compartmentation.

Bitts

Bitts are paired vertical wooden or metal posts mounted either aboard a ship or on a wharf, pier or quay. The posts are used to secure mooring lines, ropes, hawsers, or cables. Bitts aboard wooden sailing ships were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Bitts are carefully manufactured and maintained to avoid any sharp edges which might chafe and weaken the mooring lines.

Hydraulic tanker Type of vessel

An hydraulic tanker is an oil tanker designed to use water as an incompressible fluid for loading and unloading petroleum cargo. Each cargo tank is kept full at all times so oil floating on water will be pressed against the top of the tank. A cargo tank initially filled with water is loaded with the desired quantity of oil by pumping oil into the top of the tank displacing water which overflows through an opening at the bottom of the tank. The cargo tank is unloaded by removing oil from the top of the tank as water is admitted at the bottom.
