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 . The line where the hull meets the water surface is called the waterline .

34-408: The lazarette or lazaret (sometimes lazaretto ) of a boat is an area near or aft of the cockpit . The word is similar to and probably derived from lazaretto . A lazarette is usually a storage locker used for gear or equipment a sailor or boatswain would use around the decks on a sailing vessel. It is typically found below the weather deck in the stern of the vessel and is accessed through

68-520: A cargo hatch (if accessed from the main deck) or a doorway (if accessed from below decks). The equipment usually stored in a lazarette would be spare lines, sails, sail repair, line and cable splicing repair equipment, fenders, bosun chair , spare blocks, tools, and other equipment. The name derives from the Biblical story of Saint Lazarus , who in Christian belief was raised from the dead out of

136-545: A hull with rounded bilges (the chine creates turbulence and drag resisting the rolling motion, as it moves through the water, the rounded-bilge provides less flow resistance around the turn). In rough seas, this can make the boat roll more, as the motion drags first down, then up, on a chine: round-bilge boats are more seakindly in waves, as a result. Chined hulls may have one of three shapes: Each of these chine hulls has its own unique characteristics and use. The flat-bottom hull has high initial stability but high drag. To counter

170-466: A lower-horsepower engine but will pound more in waves. The deep V   form (between 18   and 23   degrees) is only suited to high-powered planing boats. They require more powerful engines to lift the boat onto the plane but give a faster, smoother ride in waves. Displacement chined hulls have more wetted surface area, hence more drag, than an equivalent round-hull form, for any given displacement. Smooth curve hulls are hulls that use, just like

204-433: A sail. Waterline: where the water surface meets the ship's hull. Weather: side or direction from which wind blows (same as "windward"). Windward: side or direction from which wind blows (opposite of "leeward"). Date of first use [ edit ] "Aboard": 14th century "Aft": 1580 "Outboard": 1694 "Inboard": 1830 "Belowdecks": 1897.

238-435: A seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft . In a typical modern steel ship, the hull will have watertight decks, and major transverse members called bulkheads . There may also be intermediate members such as girders , stringers and webs , and minor members called ordinary transverse frames, frames, or longitudinals, depending on

272-443: A ship, or down to a lower deck. Bilge: the underwater part of a ship between the flat of the bottom and the vertical topsides Bottom: the lowest part of the ship's hull . Bow: front of a ship (opposite of "stern") Centerline or centreline: an imaginary, central line drawn from the bow to the stern. Fore or forward: at or toward the front of a ship or further ahead of a location (opposite of "aft") Preposition form

340-466: A vessel, such as fore , aft , astern , aboard , or topside . Terms [ edit ] Abaft (preposition): at or toward the stern of a ship, or further back from a location, e.g. "the mizzenmast is abaft the mainmast". Aboard: onto or within a ship, or in a group. Above: a higher deck of the ship. Aft (adjective) : toward the stern (rear) of a ship. For example, "Able Seaman Smith; lie aft!" or "What's happening aft?". Comparative

374-472: Is "after", e.g. "the mizzenmast is after than the mainmast". The difference between "aft" and "stern" is that aft is the inside (on board) rearmost part of the vessel, while stern refers to the outside (offboard) rearmost part of the vessel. The stern is opposite the bow, the outside (offboard) of the front of the boat. The term derives from the Old English æftan (“behind”). Adrift: floating in

408-409: Is "before", e.g. "the mainmast is before the mizzenmast". Inboard: attached inside the ship. Keel : the bottom structure of a ship's hull . Leeward: side or direction away from the wind (opposite of "windward"). On deck: to an outside or muster deck (as "all hands on deck"). On board: on, onto, or within the ship Onboard: somewhere on or in the ship. Outboard: attached outside

442-399: Is a centerline longitudinal member called a keel . In fiberglass or composite hulls, the structure may resemble wooden or steel vessels to some extent, or be of a monocoque arrangement. In many cases, composite hulls are built by sandwiching thin fiber-reinforced skins over a lightweight but reasonably rigid core of foam, balsa wood, impregnated paper honeycomb, or other material. Perhaps

476-493: Is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in

510-423: Is easily unsettled in waves. The multi-chine hull approximates a curved hull form. It has less drag than a flat-bottom boat. Multi chines are more complex to build but produce a more seaworthy hull form. They are usually displacement hulls. V or arc-bottom chine boats have a V   shape between 6°   and 23°. This is called the deadrise angle. The flatter shape of a 6-degree hull will plane with less wind or

544-615: The Yngling and Randmeer . Hull forms are defined as follows: Block measures that define the principal dimensions. They are: Form derivatives that are calculated from the shape and the block measures. They are: Coefficients help compare hull forms as well: Note: C b = C p ⋅ C m {\displaystyle C_{b}=C_{p}\cdot C_{m}} Use of computer-aided design has superseded paper-based methods of ship design that relied on manual calculations and lines drawing. Since

578-409: The shore or land. Astarboard: toward the starboard side of a ship (opposite of "aport"). Astern (adjective) : toward the rear of a ship (opposite of "forward"). Athwartships: toward the sides of a ship. Aweather: toward the weather or windward side of a ship. Aweigh: just clear of the sea floor, as with an anchor. Below: a lower deck of the ship. Belowdecks: inside or into

612-516: The structural arrangement . The uppermost continuous deck may be called the "upper deck", "weather deck", "spar deck", " main deck ", or simply "deck". The particular name given depends on the context—the type of ship or boat, the arrangement, or even where it sails. In a typical wooden sailboat, the hull is constructed of wooden planking, supported by transverse frames (often referred to as ribs) and bulkheads, which are further tied together by longitudinal stringers or ceiling. Often but not always there

646-445: The waterline , giving less resistance and more speed. With a greater payload, resistance is greater and speed lower, but the hull's outward bend provides smoother performance in waves. As such, the inverted bell shape is a popular form used with planing hulls. A chined hull does not have a smooth rounded transition between bottom and sides. Instead, its contours are interrupted by sharp angles where predominantly longitudinal panels of

850-432: The ability to steer during heavy weather is of the utmost importance to vessel safety. The lazarette also represents a vulnerability in that the large hull penetrations required for rudders and shafts for propulsion through the vessel's hull generally reside there.

884-523: The curved hulls, a centreboard, or an attached keel. Semi round bilge hulls are somewhat less round. The advantage of the semi-round is that it is a nice middle between the S-bottom and chined hull. Typical examples of a semi-round bilge hull can be found in the Centaur and Laser sailing dinghies . S-bottom hulls are sailing boat hulls with a midships transverse half-section shaped like an s . In

918-487: The earliest proper hulls were built by the Ancient Egyptians , who by 3000 BC knew how to assemble wooden planks into a hull. Hulls come in many varieties and can have composite shape, (e.g., a fine entry forward and inverted bell shape aft), but are grouped primarily as follows: At present, the most widely used form is the round bilge hull. With a small payload, such a craft has less of its hull below

952-412: The high drag, hull forms are narrow and sometimes severely tapered at bow and stern. This leads to poor stability when heeled in a sailboat. This is often countered by using heavy interior ballast on sailing versions. They are best suited to sheltered inshore waters. Early racing power boats were fine forward and flat aft. This produced maximum lift and a smooth, fast ride in flat water, but this hull form

986-417: The hull meet. The sharper the intersection (the more acute the angle), the "harder" the chine. More than one chine per side is possible. The Cajun "pirogue" is an example of a craft with hard chines. Benefits of this type of hull include potentially lower production cost and a (usually) fairly flat bottom, making the boat faster at planing . A hard chined hull resists rolling (in smooth water) more than does

1020-487: The s-bottom, the hull has round bilges and merges smoothly with the keel, and there are no sharp corners on the hull sides between the keel centreline and the sheer line. Boats with this hull form may have a long fixed deep keel, or a long shallow fixed keel with a centreboard swing keel inside. Ballast may be internal, external, or a combination. This hull form was most popular in the late 19th and early to mid 20th centuries. Examples of small sailboats that use this s-shape are

1054-405: The ship. Port: the left side of the ship, when facing forward (opposite of "starboard"). Starboard: the right side of the ship, when facing forward (opposite of "port"). Stern: the rear of a ship (opposite of "bow"). Topside: the top portion of the outer surface of a ship on each side above the waterline. Underdeck: a lower deck of a ship. Yardarm: an end of a yard spar below

1088-444: The tomb by Jesus . On the old square-rigged sailing ships it was located in the stern of the ship. The original purpose was to store the bodies of important passengers or crew who had died on the voyage (lesser seamen would be buried at sea). In modern shipbuilding and for powerboats of most sizes, the lazarette is the location of the steering gear equipment for the vessel. This area is particularly sensitive to flooding and damage, as
