S2 7.3
The S2 7.3 is an American trailerable sailboat that was designed by Arthur Edmunds as a racer- cruiser and first built in 1978. The designation indicates the approximate length overall in meters.Henkel, Steve: ''The Sailor's Book of Small Cruising Sailboats'', page 307. International Marine/McGraw-Hill, 2010. Production The design was built by S2 Yachts in Holland, Michigan, United States from 1978 until 1987, with 404 boats completed, but it is now out of production. Design The S2 7.3 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a slightly reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel or optional shoal draft keel that was designed by Graham & Schlageter. It displaces and carries of lead ballast. The boat has a draft of with the standard keel and with the optional shoal draft keel. The boat is normally fitted with a small outboard motor ...

Arthur Edmunds
Arthur Edmunds (May 18, 1933 – July 21, 2005) was an American naval architect, credited with designing 29 sailboats as well as other boats of various types and forms. He is recognized as a top naval architect in the US. Edmunds's best known production sailboat was the Allied Princess 36. Early life Arthur H. Edmunds Jr. was born in Philadelphia, Pennsylvania on May 18, 1933. He attended the US Coast Guard Academy in New London, Connecticut. He served in the United States Coast Guard and became a lieutenant in September 1962. He became a marine architect and a member of the Society of Naval Architects and Marine Engineers. Career After completing his military service, Edmunds worked at a shipyard before joining Chris Craft as a sailing yacht designer before starting his own design firm in 1968 in Ft. Lauderdale, Florida. Edmunds' design firm operated for 30 years. Leon Slikkers, founder of Slikcraft, and later S2 Yachts, hired Edmunds, who became "S2's in-house designer." E ...

Keelboat
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970s Sailboat Type Designs
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

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 ...

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 toi ...

Companionway
In the architecture of a ship, a companion or companionway is a raised and windowed hatchway in the ship's deck (ship), 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
"V"-berth
A berth is a bed or sleeping accommodation on vehicles. Space accommodations have contributed to certain common design elements of berths. Beds in boats or ships While beds on large ships are little different from those on shore, the lack of space on smaller yachts means that bunks must be fit in wherever possible. Some of these berths have specific names: ;V-berth: Frequently yachts have a bed in the extreme forward end of the hull (usually in a separate cabin called the forepeak). Because of the shape of the hull this bed is basically triangular, though most also have a triangular notch cut out of the middle of the aft end, splitting it partially into two separate beds and making it more of a V shape, hence the name. This notch can usually be filled in with a detachable board and cushion, creating something more like a double bed (though with drastically reduced space for the feet; 12" wide is typical). The term "V-berth" is not widely used in the UK, instead the cabin a ... [...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] |
