Laser Vortex
The Laser Vortex is a high performance sailing dinghy designed by Jo Richards and awarded the "Sailboat of the Year" title on its introduction in 2000. It is a tunnel hulled single hander that has a trapeze and an optional asymmetrical spinnaker. It is manufactured by White Formula UK Ltd under licence from a consortium headed up by Jonathan Carter. Jo Richard remains the owner of the design. Laser Performance are no longer involved with the Vortex. In 2013 the decision was made to drop 'Laser' from the name, the boat is now known only as the Vortex. The development of the Asymmetric 'kit' by Association Chairman and keen Vortex enthusiast Keith Escritt has brought new life to the class, with over 100 boats now flying the asymmetric option. In handicap racing the Vortex sails off a Portsmouth Yardstick The Portsmouth Yardstick (PY) or Portsmouth handicap scheme is a term used for a number of related systems of empirical handicapping used primarily in small sailboat racing.

Dinghy
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina. The term "dinghy towing" sometimes is used to refer to the practice of towing a car or other smaller vehicle behind a motorhome, by analogy to towing a dinghy behind a yacht. Etymology The term is a loanword from the Bengali ', Urdu ', and Hindi '. Types Dinghies usually range in length from about . Larger auxiliary vessels are generally called tenders, pinnaces or lifeboats. Folding and take-down multi-piece (nesting) dinghies are used where space is limited. Some newer dinghies have much greater buoyancy, giving them more carrying capacity than older ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnel Hull
A tunnel hull is a type of boat hull that uses two typically planing hulls with a solid centre that traps air. This entrapment then creates aerodynamic lift in addition to the planing (hydrodynamic) lift from the hulls. Many times this is attributed to ground effect. Theoretical research and full-scale testing of tunnel hulls has demonstrated the dramatic contributions of 'close-proximity ground effect' on enhanced aerodynamic lift/drag in operation of performance tunnel hull designs."Secrets of Tunnel Boat Design", JDRussell,P.Eng. () Tunnel hulls are distinguishable from other catamarans by the typical close hull spacing and solid deck in between the hulls. Formula 1 powerboats have a tunnel hull catamaran design allowing them to go faster. Tunnel hulls are a common design in offshore powerboat racing.

Single Handed Sailing
The sport and practice of single-handed sailing or solo sailing is sailing with only one crewmember (i.e., only one person on board the vessel). The term usually refers to ocean The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the wo ... and long-distance sailing and is used in yacht racing, competitive sailing and among Cruising (maritime), Cruisers. Terminology In sailing, a hand is a member of a ship's crew. "Single-handed" therefore means with a crew of one, i.e., only one person on the vessel. The term "single-handed" is also used more generally in English to mean "done without help from others" or, literally, "with one hand". In the sailing community, the term "crewed" (or sometimes "fully-crewed") is used to mean sailing with a crew of more than one, in order to distinguish even ...
