Cape Dory 330
The Cape Dory 330 is an American sailboat that was designed by Carl Alberg as a cruiser and first built in 1985. The Cape Dory 330 is a development of the Cape Dory 33, with a bowsprit and cutter rig, plus interior changes. Production The design was built by Cape Dory Yachts in the United States. The company built 27 examples of the type between 1985 and 1988, but it is now out of production. Design The Cape Dory 330 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cutter rig, a spooned raked stem, a bowsprit, a raised counter transom, a keel-mounted rudder controlled by a wheel and a fixed long keel. It displaces and carries of ballast. The boat has a draft of with the standard keel fitted. The boat is fitted with an inboard engine for docking and maneuvering. The galley is located on the port side at the foot of the companionway steps and includes a sink and two-burner stove. The head is forward on the starboard side and has a pri ...

Carl Alberg
Carl Alberg (11 April 1901 – 31 August 1986) was a Swedish born naval architect known for his influence in early fiberglass boats. Career Alberg moved to the United States in 1925 where he began working as a rigger then later as a spar maker. Alberg was then hired by John Alden as a designer. His successful career and current fame as a designer however can be linked back to his partnership with Pearson Yachts and early fiberglass yacht construction. Their first collaboration was the Pearson Triton, a 28 foot fiberglass yacht which today is still frequently seen sailing oceans around the world. Alberg later designed several other models for Pearson yachts. He also designed the first model for Bristol yachts. One of his most famous and popular designs is also one of his earliest, the Alberg 30 which was built by Whitby Boatworks in Canada as a one design club racer. This boat had a record breaking production run of over 750 boats spanning 22 years and proved a good platf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raked Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On small ...

Hull Speed
Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode will appear to be climbing up the back of its bow wave. From a technical perspective, at hull speed the bow and stern waves interfere constructively, creating relatively large waves, and thus a relatively large value of wave drag. Ship drag for a displacement hull increases smoothly with speed as hull speed is approached and exceeded, often with no noticeable inflection at hull speed. The concept of hull speed is not used in modern naval architecture, where considerations of speed/length ratio or Froude number are considered more helpful. Background As a ship moves in the water, it creates standing waves that oppose its movement. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacking (sailing)
Tacking is a sailing maneuver by which a sailing vessel, whose desired course is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. The opposite maneuver to tacking is called 'jibe', or 'wearing' on square-rigged ships, that is, turning the stern through the wind. No sailing vessel can move directly upwind, though that may be the desired direction, making this an essential maneuver of a sailing ship. A series of tacking moves, in a zig-zag fashion, is called beating, and allows sailing in the desired direction. This maneuver is used for different effects in races, where one ship is not only sailing in a desired direction, but also concerned with slowing the progress of competitors. The need for tacking Sailing ships cannot proceed directly into the wind, but often need to go in that direction. Movement is achieved by tacking. If a v ...

Mainsheet Traveler
A traveller is a part of the rigging of a boat or ship that provides a moving attachment point for a rope, sail or yard to a fixed part of the vessel. It may take the form of anything from a simple ring on a metal bar or a spar to, especially in a modern yacht, a more complex "car" – a component with bearing-mounted wheels running on a shaped aluminium extrusion. There are three common examples of the use of a traveller. The sheet of a sail is attached to a traveller on the horse, allowing the sail's clew to be positioned to leeward on each tack, thereby giving a more aerodynamically efficient position of the sail. A jib may be attached to a bowsprit with a traveller. This allows the sail to be set and handed without having to go out onto the bowsprit. Lastly, the yard of a lugsail is usually attached to the mast using a traveller. This often consists of a metal ring around the mast with a hook above and below the ring for, respectively, the halyard and the yard to fasten. A tr ...

Boom (sailing)
In sailing, a boom is a spar (pole), along the of a fore and aft rigged sail, that greatly improves control of the angle and shape of the sail. The primary action of the boom is to keep the ''foot'' flatter when the sail angle is away from the centerline of the boat. The boom also serves as an attachment point for more sophisticated control lines. Because of the improved sail control it is rare to find a non-headsail without a boom, but lateen sails, for instance, are loose-footed. In some modern applications, the sail is rolled up into the boom for storage or reefing (shortening sail). Boom attachment The forward end of the boom attaches to a mast just below the sail, with a joint called the gooseneck. The gooseneck pivots allowing the other end of the boom to move freely. The clew (back corner) of the sail attaches to the free end of the boom. The entire ''foot'' of the sail may be attached to the boom or just the clew. If the ''foot'' is not attached to the boom, ...

Sheet (sailing)
In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail. Terminology In nautical usage the term "sheet" is applied to a line or chain attached to the lower corners of a sail for the purpose of extension or change of direction. The connection in derivation with the root "shoot" is more clearly seen in "sheet-anchor", one that is kept in reserve, to be "shot" in case of emergency. Fore-and-aft rigs Fore-and-aft rigs comprise the vast majority of sailing vessels in use today, including effectively all dinghies and yachts. The sheet on a fore-and-aft sail controls the angle of the sail to the wind, and should be adjusted to keep the sail just filled. Most smaller boats use the Bermuda rig, which has two or three sets of sheets: * The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainsail
A mainsail is a sail rigged on the main mast of a sailing vessel. * On a square rigged vessel, it is the lowest and largest sail on the main mast. * On a fore-and-aft rigged vessel, it is the sail rigged aft of the main mast. The sail's foot is normally attached to a boom. (In extremely heavy weather, the mainsail may be lowered, and a much smaller trysail hoisted in its place). Historical fore-and-aft rigs used a four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; Prout catamarans typically have a mainmast stepped further aft than in a standard sloop, so that the mainsail is much smaller than the foresail. Bermuda rig The modern Bermuda rig uses a triangular mainsail aft of the mast, closely coordinated with a jib for sailing upwind. A large overlapping jib or genoa is often larger than the mainsail. In downwind conditions (with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Head (watercraft)
The head (pl. heads) is a ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the ship. Design In sailing ships, the toilet was placed in the bow somewhat above the water line with vents or slots cut near the floor level allowing normal wave action to wash out the facility. Only the captain had a private toilet near his quarters, at the stern of the ship in the quarter gallery. The plans of 18th-century naval ships do not reveal the construction of toilet facilities when the ships were first built. The Journal of Aaron Thomas aboard HMS ''Lapwing'' in the Caribbean Sea in the 1790s records that a canvas tube was attached, presumably by the ship's sailmaker, to a superstructure beside the bowsprit near the figurehead, ending just above the normal waterline. In many modern boats, the heads look similar to seated flush toilets but use a system of valves and pumps that brings sea water into the to ...

Companionway
In the architecture of a ship, a companion or companionway is a raised and windowed hatchway in the ship's deck, with a ladder leading below and the hooded entrance-hatch to the main cabins. A companionway may be secured by doors or, commonly in sailboats, ''hatch boards'' which fit in grooves in the companionway frame. This allows the lowest board to be left in place during inclement weather to minimize water infiltration. The term may be more broadly used to describe any ladder between decks.

Galley (kitchen)
The galley is the compartment of a ship, train, or aircraft where food is cooked and prepared. It can also refer to a land-based kitchen on a naval base, or, from a kitchen design point of view, to a straight design of the kitchen layout. Ship's cooking area A galley is the cooking area aboard a vessel, usually laid out in an efficient typical style with longitudinal units and overhead cabinets. This makes the best use of the usually limited space aboard ships. It also caters for the rolling and heaving nature of ships, making them more resistant to the effects of the movement of the ship. For this reason galley stoves are often gimballed, so that the liquid in pans does not spill out. They are also commonly equipped with bars, preventing the cook from falling against the hot stove. A small cooking area on deck was called a caboose or ''camboose'', originating from the nl, kombuis, which is still in use today. In English it is a defunct term used only for a cooking area that is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inboard Engine
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th century. During the 20th century it was replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Marine nuclear reactors, which appeared in the 1950s, produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
