The next higher decks are referred to as the 02 level, the 03 level, and so on. 01 level is the term used in naval services to refer to the deck above the main deck.However, there are also various common historical names and types of decks: In vessels having more than one deck there are various naming conventions, numerically, alphabetically, etc. Prince Regent Pedro of Braganza (pointing) and others on the deck of the Brazilian frigate União after the failed Avilez rebellion, 1822 Eastern designs developed earlier, with efficient middle decks and minimalist fore and aft cabin structures across a range of designs. Weather decks in Western designs evolved from having structures fore (forward or front) and aft (rear) of the ship mostly clear in the 19th century, pilothouses/wheelhouses and deckhouses began to appear, eventually developing into the superstructure of modern ships. Ships may also call decks by common names, or (especially on cruise ships) may invent fanciful and romantic names for a specific deck or area of that specific ship, such as the lido deck of the Princess Cruises' Love Boat.Įquipment mounted on deck, such as the ship's wheel, binnacle, fife rails, and so forth, may be collectively referred to as deck furniture. Some merchant ships may alternatively designate decks below the primary deck, usually machinery spaces, by numbers, and those above it, in the accommodation block, by letters. So the first deck below the primary deck will be #2, and the first above the primary deck will be #A2 or #S2 (for "above" or "superstructure"). In modern ships, the interior decks are usually numbered from the primary deck, which is #1, downward and upward. ![]() The actual floor surface is called the sole the term 'deck' refers to a structural member tying the ships frames or ribs together over the keel.

It resists tension, compression, and racking forces. ![]() The deck serves as the lid to the complex box girder which can be identified as the hull. The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. Decks for some purposes have specific names. 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. 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. As is typical for a late-19th-century vessel, several deckhouses may be seen.Ī deck is a permanent covering over a compartment or a hull of a ship.
