John Deknatel
C. Raymond Hunt Associates (doing business as Ray Hunt Design) is an American naval architecture design firm, based in New Bedford, Massachusetts. The company specializes in the design of fiberglass sailboats and powerboats. The company was founded by C. Raymond Hunt and John Deknatel in 1966. Deknatel remains the chairman, while the current president is Winn Willard. In 2023 the company had seven employees. Hunt and his firm are noted as being the only designers of that period that achieved international success in both powerboat and sailboat design. Founder C. Raymond Hunt was born in 1908 and completed his formal education only as far as two years at Phillips Andover prep school. He had no formal training in naval architecture. The Hunt family were members of the Duxbury Yacht Club (DYC) in Duxbury, Massachusetts in the 1920s. In 1923, Hunt was the captain of the DYC Junior Sailing Crew, leading it to victory in the 1923 Sears Cup in Marblehead, Massachusetts. This was th ...

Paceship PY23 Sailboat 0716
Paceship Yachts Limited was a Canadian, and later American, boat builder originally based in Mahone Bay, Nova Scotia. The company was founded in 1962 and specialized in the design and manufacture of fiberglass sailboats. History The company's predecessor was the Mahone Bay Plycraft Company Ltd, which sold plywood boats as kits for amateur construction, as well as completed boats. These were marketed under various brand names. The Industrial Shipping Company Limited of Nova Scotia (ISC) produced plywood boats for Mahone Bay Plycraft in its Mahone Bay factory, until the building burned down in 1956. The factory was rebuilt and plywood boat construction restarted, but it quickly shifted to building boats from a then-new material, fibreglass, becoming one of the earliest builders of fibreglass small powerboats and sailboats. By 1962 the sailboats were produced under the Paceship name and it became a division of ISC. The Paceship division was bought out in 1965 by the Atlantic Brid ...

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] |
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 a ...

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] |
Midget Ocean Racing Club
The Midget Ocean Racing Club (MORC) is an American association based in Severna Park, Maryland, that promotes and organizes ocean racing for small sailboats under a handicapping rule. History Founded in 1954, the club was formally organized as ''The Midget Ocean Racing Club, Inc.'', on 16 November 1972 as a Maryland domestic corporation. The club has a board of governors, comprising the commodores of each station (local MORC chapter), plus the national officers of the club. Started as an ocean racing class for boats too small for the existing off-shore racing classes, the MORC-class boats were initially or less in length, although this was expanded in 1958 to just under and in 1978 to . In 1978 MORC moved to include one-design racing. The rule changes allowed separate starts for races when 20 or more boats of the same design are competing. The organization of one-design fleets was the jurisdiction of the local station. The Western Long Island Sound station was the lead cha ...

Trailer (vehicle)
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. United States In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle, high, long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight that travels over land in North America. Types ...

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 out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masthead Sloop
A masthead rig on a sailing vessel consists of a forestay and backstay both attached at the top of the mast. The Bermuda rig can be split into two groups: the masthead rig and the fractional rig. The masthead rig has larger and more headsails, and a smaller mainsail, compared to the fractional rig. The major advantage a masthead sloop has over a fractional one, is that the jib is larger. Since the jib has no mast in front of it to cause turbulent airflow over it, it is considered much more efficient than the main, especially for sailing up wind. Also, since the fore stay is attached to the top of the mast, it pulls directly against the back stay. Tightening the back stay, then, increases the tension on the fore stay. This is useful because the jib needs considerable fore stay tension to set well. This need increases in direct proportion to the wind speed and jib size. Increasing the tension on the back stay does not tend to bend the mast, as it would on a fractional sloop. It put ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahogany
Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species. Description The three species are: *Honduran or big-leaf mahogany ('' Swietenia macrophylla''), with a range from Mexico to southern Amazonia in Brazil, the most widespread species of mahogany and the only genuine mahogany species commercially grown today.

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 teak. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balsa
''Ochroma pyramidale'', commonly known as the balsa tree, is a large, fast-growing tree native to the Americas. It is the sole member of the genus ''Ochroma''. The tree is famous for its wide usage in woodworking, with the name ''balsa'' being the Spanish word for "raft." A deciduous angiosperm, ''Ochroma pyramidale'' can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight.
