The strength of ships is a topic of key interest to naval architects and shipbuilders. Ships which are built too strong are heavy, slow, and cost extra money to build and operate since they weigh more, whilst ships which are built too weakly suffer from minor hull damage and in some extreme cases catastrophic failure and sinking.
Hogging is the stress a ship's hull or keel experiences that causes the center or the keel to bend upward. Sagging is the stress a ship's hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves.
Frames support the hull and give the ship its shape and strength. In wooden shipbuilding, each frame is composed of several sections, so that the grain of the wood can follow the curve of the frame. Starting from the keel, these are the floor (which crosses the keel and joins the frame to the keel), the first futtock , the second futtock , the ...
If there were insufficient longitudinal strength, the hull would bend and eventually "break its back." [1] In the days of wooden ship construction, this was the only practical way to build a large ship since the inside and deck planking had to be laid longitudinally, with the deck planking laid upon transverse beams connected to the frames ...
A deck is a permanent covering over a compartment or a hull [1] 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 ...
Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...

A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy ), 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 .
