Redline 41
The Redline 41 is a series of sailboat designs, first built in 1967 and that remained in production in 2017. The first two designs were by Cuthbertson & Cassian and the more recent one by Mark Mills. The three different boats that have carried the Redline 41 name are all unrelated designs. Design and development All the Redline 41 designs are small recreational keelboats, built predominantly of fiberglass and other composites. The earlier two designs were predominately built as cruising sailboats, whereas the most recent boat was conceived as a racer that can also be used for cruising. The original Redline 41, later called the Mark I, was designed by Cuthbertson & Cassian and produced by Bruckmann Manufacturing, although only two were built between 1967 and the following year. The second model, known as the Redline 41 Mark II, was also designed by Cuthbertson & Cassian and produced by Bruckmann Manufacturing starting in 1969, which became part of C&C Yachts that same year.

Cuthbertson & Cassian
C&C Yachts was a builder of high-performance fiberglass monohull sailboats with production facilities in Canada, Germany, and the United States. C&C designed and constructed a full range of production line cruiser-racer boats, as well as custom one-off and short production run racing and cruising boats. C&C boats ranged in size from as small as to as large as . C&C also produced a line of bluewater cruising boats in the to range under its Landfall brand. In addition, C&C designed sailboats for production by a number of other manufacturers such as CS Yachts, Mirage Yachts, Northern Yachts, Ontario Yachts, Paceship Yachts, and Tanzer Industries. C&C was founded in 1969 as a public company in Canada, which resulted from a joint venture among several companies and design teams. At the peak of its market success, the company supplied 50% of the Canadian market and 20% of the US market. The company name, C&C Yachts, came from the names of two of the founding designers, Geor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brand
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a product or com ...

Sloop
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is somet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fractional Rig
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast. The forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24. Fractional rigs were introduced on race boats in order to allow more controllability of the surface of the mainsail and also less drag when sailing upwind. According to one manufacturer, "a key to making fast boats easier to sail than slow boats is the 'fractio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Fibre
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English The use of the English language in current and former member countries of the Commonwealth of Nations was largely inherited from British colonisation, with some exceptions. English serves as the medium of inter-Commonwealth relations. Many ...), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermosetting polymer, thermoset resin such as epoxy, but oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-glass
Glass fiber ( or glass fibre) is a material consisting of numerous extremely fine fibers of glass. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of glass fiber was only made possible with the invention of finer machine tooling. In 1893, Edward Drummond Libbey exhibited a dress at the World's Columbian Exposition incorporating glass fibers with the diameter and texture of silk fibers. Glass fibers can also occur naturally, as Pele's hair. Glass wool, which is one product called "fiberglass" today, was invented some time between 1932 to 1933 by Games Slayter of Owens-Illinois, as a material to be used as thermal building insulation. It is marketed under the trade name Fiberglas, which has become a genericized trademark. Glass fiber when used as a thermal insulating material is specially manufactured with a bonding agent to trap many small air cells, resulting in the characteristically air-filled low-density "glass wool" family of prod ...

Warren, Rhode Island
Warren is a town in Bristol County, Rhode Island, United States. The population was 11,147 at the 2020 census. History Warren was the site of the Pokanoket Indian settlement of Sowams located on a peninsula within the Pokanoket region. The region consisted of over 60 settlements under the authority of Chief Massasoit (sometimes called Osamequin) who controlled the land from Plymouth to the eastern shores of Narragansett Bay. English colonists Edward Winslow and Stephen Hopkins from Plymouth Colony first visited there in July, 1621. Winslow and John Hampden saved Massasoit's life two years later and gained an important ally and lifelong friend. The colonists set up a trading post by 1632 on the banks of the Kickamuit River where they traded English goods for furs and other items. Roger Williams was banished from Salem, Massachusetts, in January, 1636, and fled to Sowams, becoming ill on the way. He was sheltered by Massasoit in Sowams until he recovered over the winter mo ...

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 ...

Universal Atomic 4
The Universal Atomic 4 is a four-cylinder, gasoline engine produced by the Universal Motor Company between 1949 and 1984 for use as auxiliary power on sailboats. Both and versions of the engine were produced. Over 40,000 of the engines were produced during that time, with an estimated 20,000 still in use today. The Universal Atomic 4 was very popular in C&C, Whitby Boatworks, Northern, Catalina Yachts and Pearson Yachts sailboats, up through 1985. Starting in the early 1970s the brand Yanmar became very popular as an auxiliary power diesel engine for sailboats, in response Universal began offering a marinized version of a Kubota diesel (tractor) engine in 1976, which was popular with sailboat manufacturers, in particular Catalina. As Yanmar diesel engines continued to gain in popularity, the Universal Atomic Four gasoline engines continued to lose market share rapidly. By 1989 Yanmar had eclipsed Universal in the diesel auxiliary market with 45% market share to 42% for Univer ... [...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] |
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] |
