Structural Elements of a Ship's Hull. This diagram shows the key structural elements of a ship's main hull (excluding the bow, stern, and deckhouse). Deck plating (a.k.a. Main Deck, Weatherdeck or Strength Deck) Transverse bulkhead; Inner bottom shell plating; Hull bottom shell plating; Transverse frame (1 of 2) Keel frame
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.
The keel is the bottom-most longitudinal structural element of a watercraft. On some sailboats, it may have a hydrodynamic and counterbalancing purpose as well. The laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction.
In seafaring, under keel clearance (UKC) is the height between seabed and the keel or hull of a ship. [ 1 ] [ 2 ] [ 3 ] It is used to ensure sufficient navigable water is available for ships at sea. [ 4 ] [ 5 ] [ 1 ] [ 6 ] It is most commonly defied as Master mariners should ensure there is sufficient minimum UKC for their ships ; ports should ...

Keel: the main structural member of a traditional vessel, running fore and aft from bow to stern on its centerline. It provides ballast for stability, and resistance to leeway moving through the water. Keelson: an internal beam fixed to the top of the keel to strengthen the joint of the upper members of the boat to the keel.
A bilge keel. A bilge keel is a long, often V-shaped metal fin welded along the length of the ship at the turn of the bilge. Bilge keels are employed in pairs (one for each side of the ship). Rarely, a ship may have more than one bilge keel per side. Bilge keels increase hydrodynamic resistance when a vessel rolls, limiting the amount of roll.
Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation ...
