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 .
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
The bow (/ b aʊ /) is the forward part of the hull of a ship or boat, [1] the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. [2] Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline.
The boat building industry provides for the design, manufacturing, repair and modification of human-powered watercrafts, sailboats, motorboats, airboats and submersibles, and caters for various demands from recreational (e.g. launches, dinghies and yachts), commercial (e.g. tour boats, ferry boats and lighters), residential , to professional (e ...
Royal Navy World War II motor torpedo boat (MTB) planing at speed on calm water showing its hard-chine hull. Note how most of the bow of the boat is out of the water.. The scow in particular, in the form of the scow schooner, was the first significant example of a hard-chine sailing vessel.
The aft part of the vessel is supported in the water by the lower half of the propeller, which is designed to operate semi-submerged at all times. The goal is to keep as little of the boat in contact with the water as possible, as water is much denser than air, exerting more drag on the vehicle. Essentially the boat 'flies' over the surface of ...
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes , or in protected coastal areas.
