Thunderbird 26
The Thunderbird class sailboat was designed in 1958 by Seattle Washington naval architect Ben Seaborn, in response to a request from the Douglas Fir Plywood Association (now APA - The Engineered Wood Association) of Tacoma, Washington for design proposals for a sailboat that would "... be both a racing and cruising boat; provide sleeping accommodations for four crew; be capable of being built by reasonably skilled amateurs; provide auxiliary power by an outboard motor that could be easily removed and stowed; and out-perform other sailboats in its class." Design and construction T-Birds can be built of marine plywood, usually fiberglass-covered for minimum maintenance, or with a fiberglass hull and deck. The International Thunderbird Class Association (ITCA) maintains specifications of what dimensions and specifications fit the definition of the Thunderbird class. Many plywood T-Birds have been built by amateur builders, while fiberglass T-Birds usually are built by professional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monohull
image:monohull.svg, right A monohull is a type of boat having only one hull (watercraft), hull, unlike multihulled boats which can have two or more individual hulls connected to one another. Fundamental concept Among the earliest hulls were simple logs, but these were generally unstable and tended to roll over easily. Hollowing out the logs into a dugout canoe doesn't help much unless the hollow section penetrates below the log's center of buoyancy, then a load carried low in the cavity actually stabilizes the craft. Adding weight or Sailing ballast, ballast to the bottom of the hull or as low as possible within the hull adds stability. Naval architects place the center of gravity substantially below the center of buoyancy; in most cases this can only be achieved by adding weight or ballast. The use of stones and other weights as ballast can be traced back to the Ancient Rome, Romans, Phoenicians and Vikings. Modern ships carry tons of ballast in order to maintain their stabil ...

Genoa (sail)
A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and ketches. Its larger surface area increases the speed of the craft in light to moderate winds; in high wind, a smaller jib is usually substituted, and downwind a spinnaker may be used. Definition The term ''jib'' is the generic term for any of an assortment of ''headsails''. The term ''genoa'' (or genny) refers to a type of jib that is larger than the 100% foretriangle, which is the triangular area formed by the point at which the stay intersects the mast, and deck or bowsprit, and the line where the mast intersects deck at the rail. Colloquially the term is sometimes used interchangeably with ''jib''. A working jib is no larger than the 100% foretriangle. A genoa is larger, with ...

Spinnaker
A spinnaker is a sail designed specifically for sailing off the wind on courses between a reach (wind at 90° to the course) to downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be ''flown''. Nomenclature Informal names for a spinnaker are ''kite'' or ''chute'' (owing to their resemblance to a parachute in both construction and appearance). Boats may have more than one spinnaker, differentiated by a letter to indicate symmetric (S) or asymmetric (A) and a number to indicate size (with higher numbers indicating smaller size), e.g. ''A1'' would be a large asymmetric sail and ''S3'' would be a smaller symmetric sail. Operation A spinnaker is used for sailing with the direction of the wind. Symmetrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sail-plan
A sail plan is a description of the specific ways that a sailing craft is rigged. Also, the term "sail plan" is a graphic depiction of the arrangement of the sails for a given sailing craft.> In the English language, ships were usually described, until the end of the eighteenth century, in terms of their type of hull design. Using the type of rig as the main type identifer for a vessel only became common in the nineteenth century. This is illustrated by the terminology for ships in the large fleet of colliers that traded to London from the coal ports of the Northeast of England (of which was a well-known example). Many of these full-rigged ships (square rigged on all of three masts) had the hull type "bark"another common classification was "cat". In the second half of the eighteenth century, the square sails on the mizzen were often eliminated. The resulting rig acquired the name of the hull type: initially as "bark" and soon as "barque". This explains the Royal Navy's descripti ... [...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 ...
