RK 20
The RK 20 is an American trailerable sailboat that was designed by Lyle C. Hess as a cruiser and first built in 1972.Henkel, Steve: ''The Sailor's Book of Small Cruising Sailboats'', page 126. International Marine/McGraw-Hill, 2010. The RK 20 is a development of the Hess-designed Balboa 20, as is the Ensenada 20. Production The design was built by RK Industries, a subsidiary of Coastal Recreation, in the United States. It was built between 1972 and 1981, but it is now out of production. Design The RK 20 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig; a spooned, raked stem; an angled transom; a transom-hung rudder controlled by a tiller and a swing keel or fixed fin keel. The swing keel version displaces and carries of ballast, while the fin keel version displaces and carries of ballast. Two cabin designs were available, a trunk cabin and a raised deck version. The fin keel-equipped version of the boat has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sailing Yachts
A sailing yacht (US ship prefixes SY or S/Y), is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least in length and have been judged to have good aesthetic qualities. Sailboat, Sailboats that do not accommodate overnight use or are smaller than are not universally called yachts. Sailing yachts in excess of are generally considered to be Superyacht, superyachts. Sailing yachts are actively used in sport and are among categories recognized by the governing body of sailing sports, World Sailing. Etymology The term ''yacht'' originates from the Dutch language, Dutch word ''jacht'' (pl. ''jachten'', which means "hunt"), and originally referred to light, fast saili ...

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. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Keelboats
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 wa ... [...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. 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 ...

"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] |
Boat Trailer
A boat trailer is designed to launch, retrieve, carry and sometimes store boats. Commercial boat trailers Commercial hydraulic boat trailers are used by marinas, boat yards, boat haulers, boat dealers and boat builders. Generally this type of trailer is not used for storage of the boat. Self-propelled Self-propelled boat movers are not strictly trailers, but hydraulically operated boat movers, with their own tractor unit. They share all of the features of hydraulic boat trailers. Non-commercial boat trailers This type of trailer is usually used by the boat owner/operator. The trailer is also used for storage. * Roll-on, also known as a "Roller style trailer", uses rubber and/or polyurethane rollers for ease of launching and loading a boat. * Glide-path, also known as a "Float-on style trailer", allows the boat to float onto the trailer; after the trailer has been partially submerged (usually of the trailer). Since its inception, it has become quite popular compared to th ... [...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 kayaks wh ...
