The 29er is a two-person high performance sailing skiff designed by Julian Bethwaite and first produced in 1998. Derived from the Olympic class 49er class, it is raced in the ISAF Youth Sailing World Championships. [3] The 29er is able to reach high speeds fairly quickly by having a sleek and hydrodynamic hull and will often exceed the wind speed when planing both up and downwind.
The 29er class is targeted at youth, especially those training to sail the larger Olympic 49er. The Youth Sailing World Championships [ citation needed ] has adopted it to replace the Laser 2 - which was designed by Julian Bethwaite's father Frank.
The 29er has two sailors, one on trapeze. The rig features a fractional asymmetrical spinnaker; a self-tacking jib decreases the work load of the crew, making maneuvers more efficient and freeing the crew to take the mainsheet upwind and on two-sail reaches. The spinnaker rigging set-up challenges crews to be fit and coordinated, and maneuvers in the boat require athleticism due to its lack of inherent stability and the high speed with which the fully battened mainsail and jib power up. [ citation needed ]
The hull construction is of fibreglass-reinforced polyester in a foam sandwich layout. The fully battened mainsail and jib are made from a transparent Mylar laminate with orange or red Dacron trimming, while the spinnaker is manufactured from ripstop Nylon. The mast is in three parts - an aluminium bottom and middle section, with a polyester-fiberglass composite tip to increase mast bend and decrease both overall weight, and the capsizing moment a heavy mast tip can generate. Foils are aluminium or fibreglass. [ citation needed ]
The class has shown large popularity in Oceania with over 700 registered boats out of the 7000 registered worldwide [4]
The 29er has been used as equipment in the ISAF Youth Sailing World Championships.
Bethwaite and Jen Glass have also designed the 29erXX, a twin trapeze derivative of the 29er. It uses the same hull with some minor changes such as an extended gunwale and a rudder gantry, with a larger rig that includes a square-top main and masthead asymmetric spinnaker. The class became an International Sailing Federation recognised class in its own right in 2010. [ citation needed ]
In late 2012 Bethwaite announced another new version, the 29erXS, aimed at younger and/or lighter sailors. The XS features a similar rig to the XX, but of smaller size fitted to a standard 29er hull and employing a single trapeze. The main being 4.29sqm and the jib 2.13sqm, the spinnaker is similarly downsized. [48] The intention is that sailors can upgrade the rig when they are ready to move to full sized sails, and keep the hull, which will remain standard across all 29er variants.[ citation needed ]
The Tornado is a double handed multihull class recognised as an International Class by the International Sailing Federation. It was used for the Catamaran discipline at the Olympic Games from 1976 to 2008.
The Albacore is a 4.57 m (15 ft) two-person planing dinghy with fractional sloop rig, for competitive racing and lake and near-inshore day sailing. Hulls are made of either wood or fiberglass. The basic shape was developed in 1954 from an Uffa Fox design, the Swordfish. Recent boats retain the same classic dimensions, and use modern materials and modern control systems.
The GP14 is a wooden or fibreglass hulled double-handed fractional Bermuda rigged sailing dinghy designed by Jack Holt in 1949.
The 49er and 49er FX is a two-handed skiff-type high-performance sailing dinghy. The two crew work on different roles with the helm making many tactical decisions, as well as steering, and the crew doing most of the sail control. Both of the crew are equipped with their own trapeze and sailing is done while cantilevered over the water to the fullest extent to balance against the sails.
The Laser Standard or ILCA 7 is a popular one-design class of single-handed sailing dinghy, originally built by Performance Sailcraft Canada. The laser is cat rigged, with a single mainsail and is a simple, light and fast boat to sail. The Laser Standard is the original of the Laser family of dinghies, which also includes the Laser Radial and Laser 4.7, both of which use the same hull, but have smaller rigs.
The International 420 Dinghy is a sailing dinghy popular for racing and teaching. The hull is fiberglass with internal buoyancy tanks. The 420 has a bermuda rig, spinnaker and trapeze. It has a large sail-area-to-weight ratio, and is designed to plane easily. The 420 is an International class recognised by World Sailing. The name refers to the boat's length of 420 centimetres.
The International 505 is a One-Design high-performance two-person monohull planing sailing dinghy, with spinnaker, utilising a trapeze for the crew.
The Cadet is a class of sailing dinghy designed to be sailed by two children up to the age of 17. It is a one-design class, originally designed by Jack Holt in 1947. Cadets are sailed worldwide in more than 40 countries.
The Tasar is a 14.83-foot (4.52 m) fiberglass 2 person sailing dinghy with a mainsail and jib. Designed by Frank Bethwaite of Sydney in 1975, the boat was technologically advanced for its time and continues to evolve. Aimed at a husband-and-wife or parent-and-child crew hence no spinnaker, it is designed for a combined crew weight of around 140 kg. The hull weighs 68 kg, and is of sandwich foam construction. The hull has a fine angle at the bow to reduce wave impact drag with unusually clean and sharp chines aft to ensure very free planing and outstanding stability. The foam cored hull is stiff and light and the advanced hull shape, together with an innovative rig which combines a rotating mast with a fully battened main sail, allows the Tasar to plane upwind with the crew normally hiked. The wide beam and a cockpit designed for comfortable hiking make the Tasar easy, fun and very exciting to sail in winds up to 25 knots (46 km/h).
The 18 ft Skiff is considered the fastest class of sailing skiffs. The class has a long history beginning with races on Sydney Harbour, Australia in 1892 and later in New Zealand. The boat has changed significantly since the early days, bringing in new technology as it became available. Because of the need of strength, agility and skill, the class is considered to be the top level of small boat sailing. Worldwide this boat is called the "18 Foot Skiff". It is the fastest conventional non-foiling monohull on the yardstick rating, with a score of 675, coming only third after the Tornado and Inter 20.
The Laser 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996, the 3000 was developed from the Laser 2, using the original Frank Bethwaite-designed planing hull combined with a brand new self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetrical spinnaker. The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.
The RS Feva is a two-person sailing dinghy designed by Paul Handley in 2002. It is manufactured and distributed by RS Sailing. The RS Feva is an International Sailing Federation (ISAF) International Class, a Royal Yachting Association (RYA) Supported Junior Class, and has been selected by the Dansk Sejlunion and Norges Seilforbund for major sailing growth projects.
The 3000 is a racing sailing dinghy crewed by two persons with a trapeze for the crew. Launched in 1996 as the Laser 3000, the 3000 was developed from the Laser 2, using the original Frank Bethwaite-designed planing hull combined with a new designed self-draining deck by Derek Clark. Clark also re-designed the rig, using spars and sails from premium proprietary sources and replacing the symmetric spinnaker of the Laser 2 by a larger asymmetric spinnaker (gennaker). The gennaker is chute-launched and retrieved using a single halyard line, and is set on a retractable bowsprit. Helm balance and handling were improved using a shorter-footed mainsail with two full-width battens giving a larger roach. A mast with conventional spreaders replaced the now-unusual diamond arrangement of the Laser 2.
The 29erXX is a high performance sailing skiff, it was designed to allow light crews, particularly female crews, to sail twin trapeze boats and as a training boat for the more powerful 49er. The class gained International Sailing Federation Class status in May 2011, but lost it in 2014.
The SKUD 18 is a class of racing sailing boat. It is a lead-assisted skiff with a tube-launched asymmetrical and a modern high performance stayed rig. The boat was created for trials held by the International Association for Disabled Sailing who were looking for a new two person boat for an additional medal allocated to sailing for the 2008 Paralympics.
The RS700 is a single-handed racing dinghy built by RS Sailing and designed in 2000 by Nick Peters and Alex Southon as part of the RS series and built in 2001. It is raced in many sailing clubs around Britain, with a PY number of 850 and a D-PN of 73.3.
The ISAF Youth Sailing World Championships was first held in Sweden in 1971 and it has been held every year since. It is one of the key events of the federation to help promote top-level youth participation.
