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]
Tween deck: the storage space between the hold and the main deck, often retractable. Upper deck: The highest deck of the hull, extending from stem to stern. Vehicle deck: aboard amphibious assault ships the deck or decks used to carry vehicles, aboard civilian ferries and other commercial vessels a deck used for a similar purpose.

The cross-jack yard was the lowest yard on a ship's mizzen mast.

In these ships, the flight deck was the strength deck, an integral part of the hull, and was heavily armored to protect the ship and her air complement. The flight deck as the strength deck was adopted for later construction. This was necessitated by the ever-increasing size of the ships, from the 13,000 ton USS Langley in 1922 to over 100,000 ...
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 ...
