Nonsuch 30
The Nonsuch 30 is a Canadian sailboat that was designed by Mark Ellis and first built in 1978. It was the first the series of Nonsuch sailboats and was scaled upwards and down, to form a complete line of boats, from the Nonsuch 22 to the Nonsuch 40. The Nonsuch 30 hull design was used to create the 1994 Nonsuch 324, which features a carbon fibre wishbone boom, more sail area and a wing keel. Production The first in the Nonsuch line of boat designs, the concept of a cruising catboat was proposed by Toronto businessman and sailor Gordon Fisher. Ellis designed the boats and they were built by Hinterhoeller Yachts in St. Catharines, Ontario, Canada, between 1978 and 1989, with 1080 examples completed. Design The Nonsuch 30 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cat rig, an unstayed mast with a wishbone boom, a plumb stem, a vertical transom, an internally-mounted spade-type rudder controlled by a wheel and a fixed fin kee ...

Mark Ellis (yacht Designer)
Mark Ellis (born 4 February 1945 died 2025) was an American-Canadian naval architect, who designed sixteen production sailboats, along with many custom sailboats and powerboats. He is best known for his Nonsuch series of catboats, the Limestone series of powerboats and Niagara sailboats. In 2003, Dan Spurr described Ellis as "one of Canada's premier yacht designers". Ellis was born in Watertown, New York, United States and lived a major portion of his adult life in Oakville, Ontario. He died in Essex, Connecticut United States and held dual American citizenship and Canadian citizenship. Early life and education Ellis grew up in upstate New York, where his father owned a department store. As a boy Ellis worked in the store and gained his first experience with business. He applied for a degree program in naval architecture at the University of Michigan but decided not to pursue it when he discovered that it mostly focused on large ship design, instead of small boats, which was whe ...

Wing Keel
The winged keel is a sailboat keel layout first fitted on the 12-metre class yacht ''Australia II'', 1983 America's Cup winner. Design This layout was adopted by Ben Lexcen, designer of ''Australia II''. Although Ben Lexcen "had tried the winged keel idea before", there is conjecture that it was computed and designed by a Dutch aerodynamicist at the Wageningen towing tank (Netherlands Ship Model Bassin). in May 2024 A detailed article was published by the Journal of Engineering Ethics which came to the conclusion that Lexcen should not have been credited with the invention on the patent application. It also claimed that he had not been involved with the design because he had departed from Holland before the prototype work which evolved the winglets was carried out. Wings The lateral wings of Australia II are of moderate aspect ratio, forming a nearly horizontal foil, the "wing", at the bottom to provide additional effective span, in the same way as the winglets on an aircraft. ...

Alberg 30
The Alberg 30 is a Canadian sailboat, that was designed by Carl Alberg and first built in 1962. The Alberg 30 incorporates design elements from the similar Alberg Odyssey 30 of two years earlier. Production The boat was built by Whitby Boat Works in Canada, who completed more than 700 examples between 1962 and 1987, but it is now out of production. Construction was changed during the production run. Early models have a laminated wood mast brace and no liner, with a masonite-cored deck that drains overboard via the toe rail. Later models feature an aluminum mast brace inside a molded fiberglass liner, balsa-cored decks that drain through cockpit scupper drain hoses. Some boats built during the transitional period have mixed features. Design The Alberg 30 is a recreational keelboat, built predominantly of fibreglass, with wood trim. It has a masthead sloop rig, a keel-mounted rudder and a fixed long keel. It displaces and carries of iron ballast. The boat has a draft of w ...

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. ... [...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 ...

Keel
The keel is the bottom-most longitudinal structural element of a watercraft, important for stability. On some sailboats, it may have a fluid dynamics, hydrodynamic and counterbalancing purpose as well. The keel laying, laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction. Etymology The word "keel" comes from Old English language, 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 careening, careen (to clean a keel and the hull in general, often by rolling the ship on its side).

Ship's Wheel
A ship's wheel or boat's wheel is a device used aboard a ship, boat, submarine, or airship, with which a helmsman steering, steers the vessel and controls its course (navigation), course. Together with the rest of the steering mechanism, it forms part of the helm (the term ''helm'' can mean the wheel alone, or the entire mechanism by which the rudder is controlled). It is connected to a mechanical, electric Servomechanism, servo, or hydraulics, hydraulic system which alters the horizontal angle of the vessel's rudder relative to its Hull (watercraft), hull. In some modern ships the wheel is replaced with a simple toggle that remotely controls an electro-mechanical or electro-hydraulic drive for the rudder, with a rudder position indicator presenting feedback to the helmsman. History Until the invention of the ship's wheel, the helmsman relied on a tiller—a horizontal bar fitted directly to the top of the rudder post—or a whipstaff—a vertical stick acting on the arm of the sh ...

Transom (nautical)
In some boats and ships, a transom is the aft transverse surface of the hull that forms the stern of a vessel. Historically, they are a development from the canoe stern (or "double-ender") wherein which both bow and stern are pointed. Transoms add both strength and width to the stern. They may be flat or curved and they may be vertical, raked forward (known as retroussé), or raked aft. In small boats and yachts, this flat termination of the stern is typically above the waterline, but large commercial vessels often exhibit vertical transoms that dip slightly beneath the water. On cruising boats, a counter stern may be truncated to form a "truncated counter stern", in which there is a part of the stern that approximates a transom. Although that standard stern transom is typically vertical, they may be raked such that there is an overhang above the water, as at the bow. A reverse transom is angled from the waterline forwards. On smaller boats such as dinghies, transoms may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumb 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 smalle ...
