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 .
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 ...
Diagram of ship hull (1) Sagging and (2) Hogging under loads. Bending is exaggerated for illustration purposes. The primary strength, loads, and bending of a ship's hull are the loads that affect the whole hull, viewed from front to back and top to bottom.
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.
A padded V-hull is a hull shape found on both pure race boats and standard recreational craft. A variation of the more common V-hull , which has a V-section throughout the length of the vessel, a padded V-hull has a V-section at the bows and the forward part of the keel which then segues into a flat area typically 0.15 metres (5.9 in) to 0.25 ...
Model showing the cross-section of Vasa, demonstrating the hull shape created by tumblehome Tumblehome was common in sailing vessels, particularly in the latter part of the 16th century. It allowed for maximizing a vessel's beam and creating a low centre of gravity (by decreasing the amount of structure, and therefore mass, at deck level), both ...
Carvel built or carvel planking is a method of boat building in which hull planks are laid edge to edge and fastened to a robust frame, thereby forming a smooth surface. Traditionally the planks are neither attached to, nor slotted into, each other, having only a caulking sealant between the planks to keep water out.
