Alberg 22
The Alberg 22 is a Canadian trailerable sailboat, that was designed by Swedish-American naval architect Carl Alberg and first built in 1970.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 146-147. Houghton Mifflin Company, 1994. Production The design was built by Nye Yachts in Belleville, Ontario, later located in Bloomfield, Ontario, Canada. A total of 180 examples were completed before production ended. Design The Alberg 22 is a small recreational keelboat, built predominantly of fiberglass, with teak wooden handrails and toe rails, plus other trim. It has a masthead sloop rig, a raked stem, a raised transom, a keel-mounted rudder controlled by a tiller and a fixed long keel. It displaces and carries of ballast. Due to its weight and full keel it has been noted as handling like a larger boat. The boat is normally fitted with a small outboard motor of up to for docking and maneuvering. The outboard motor is fit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 platfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teak
Teak (''Tectona grandis'') is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. ''Tectona grandis'' has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs (perfect flowers). The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and other small wood projects. ''Tectona grandis'' is native to south and southeast Asia, mainly Bangladesh, India, Indonesia, Malaysia, Myanmar, Thailand and Sri Lanka, but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Performance Handicap Racing Fleet
Performance Handicap Racing Fleet (PHRF) is a handicapping system used for yacht racing in North America. It allows dissimilar classes of sailboats to be raced against each other. The aim is to cancel out the inherent advantages and disadvantages of each class of boats, so that results reflect crew skill rather than equipment superiority. PHRF is used mainly for larger sailboats (i.e., 7 meters and above). For dinghy racing, the Portsmouth yardstick handicapping system is more likely to be used. The handicap number assigned to a class of yachts is based on the yacht's speed relative to a theoretical yacht with a rating of 0. A yacht's handicap, or rating, is the number of seconds per mile traveled that the yacht in question should be behind the theoretical yacht. Most boats have a positive PHRF rating, but some very fast boats have a negative PHRF rating. If Boat A has a PHRF rating of 15 and Boat B has a rating of 30 and they compete on a 1 mile course, Boat A should finish ...

Genoa (sail)
A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and ketches. Its larger surface area increases the speed of the craft in light to moderate winds; in high wind, a smaller jib is usually substituted, and downwind a spinnaker may be used. Definition The term ''jib'' is the generic term for any of an assortment of ''headsails''. The term ''genoa'' (or genny) refers to a type of jib that is larger than the 100% foretriangle, which is the triangular area formed by the point at which the stay intersects the mast, and deck or bowsprit, and the line where the mast intersects deck at the rail. Colloquially the term is sometimes used interchangeably with ''jib''. A working jib is no larger than the 100% foretriangle. A genoa is larger, with ...

Icebox
An icebox (also called a cold closet) is a compact non-mechanical refrigerator which was a common early-twentieth-century kitchen appliance before the development of safely powered refrigeration devices. Before the development of electric refrigerators, iceboxes were referred to by the public as "refrigerators". Only after the invention of the modern day electric refrigerator did early non-electric refrigerators become known as iceboxes. The terms ''ice box'' and ''refrigerator'' were used interchangeably in advertising as long ago as 1848. Origin The first recorded use of refrigeration technology dates back to 1775 BC in the Sumerian city of Terqa. It was there that the region's King, Zimri-lim, began the construction of an elaborate ice house fitted with a sophisticated drainage system and shallow pools to freeze water in the night. Using ice for cooling and preservation was nothing new at this point, but these ice houses paved the way for their smaller counterpart, the i ...

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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lazarette
The lazarette (also spelled lazaret) 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 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 the tomb by Jesus Jesus, likely from he, יֵשׁוּעַ, translit=Yēšūaʿ, label=Hebrew/Aramaic ( AD 30 or 33), also referred to as Jesus Christ or Jesus of Nazareth (among other names an ...

Outboard Motor
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Unlike inboard motors, outboard motors can be easily removed for storage or repairs. In order to eliminate the chances of hitting bottom with an outboard motor, the motor can be tilted up to an elevated position either electronically or manually. This helps when traveling through shallow waters where there may be debris that could potentially damage the motor as well as the propeller. If the electric motor required to move the pistons which raise or lower the engine is malfunctioni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work '' De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiller
A tiller or till is a lever used to steer a vehicle. The mechanism is primarily used in watercraft, where it is attached to an outboard motor, rudder post or stock to provide leverage in the form of torque for the helmsman to turn the rudder. A tiller may also be used in vehicles outside of water, and was seen in early automobiles. On vessels, a tiller can be used by the helmsman directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel. Rapid or excessive movement of the tiller results in an increase in drag and will result in braking or slowing the boat. Description A tiller is a lever used to steer a vehicle. It provides leverage in the form of torque to turn the device that changes the direction of the vehicle, such as a rudder on a watercraft or the surface wheels on a wheeled vehicle. A tiller can be used by directly pulling or pushing it, but it may also be moved remotely using tiller lines or a ship's wheel; some kay ...
