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 49er was designed by Julian Bethwaite (the son of Frank Bethwaite) and developed by a consortium consisting of Bethwaites, Performance Sailcraft Japan, Peter Johnston, and Ovington boats. [3] The boat has been an Olympic class since it was selected by the International Sailing Federation to be the men's high performance double handed dinghy Sydney Summer Games of 2000. Its derivative featuring a re-designed rig, the 49er FX, was selected by World Sailing to be the women's high performance double-hander at the Rio Summer Olympics of 2016.
The 49er's name comes from its hull length of 4.99 metres (16 ft 4 in). It incorporates ideas developed in Julian Bethwaite's 18ft Skiffs, notably the Prime Computer series of boats, which were double handers. [4]
To handle a large and powerful sail area, the mast uses a square topped sail that causes the upper main to twist off and flatten, allowing a controllable sail with fast gust response and reducing the heeling moment. The use of solid wings, rather than tubes as on similar boats (RS800 etc.), makes it easier for the crew to run across the deck from gunwale to gunwale during maneuvers.
The 49er made its first Olympic appearance at the Sydney Olympics in 2000 and has continued to grow in popularity ever since.
With a Portsmouth yardstick Handicap of 740 the 49er is the fastest two person one-design monohull dinghy.
In 2009 the boat received a new rig design, including a larger fully carbon mast (replacing the aluminum mast) and square top (roach) mainsail. [5]
As a one design class, the 49er has two licensed suppliers, Mackay Boats in Oceania and Ovington in Europe.
The hull is made of Epoxy GRP and foam sandwich laminate with carbon fibre in high load areas. It includes two solid wings, also called racks, that clip into the side to increase righting moment of the trapezing crew. [6] Its length was fixed at 4.99 metres because the ISAF brief for the high performance Olympic class dinghy called for a 5-metre boat, but Tokao Otani, a member of the development consortium, pointed out that there was a tariff in Japan for boats over 5 metres long. [3] It has a fine entry to efficiently transition between the low speed displacement, and high speed planing modes. [7] According to the International 49er class rules, the minimum hull weight including all permanent fittings can not be less than 94.0 kg. [8]
Southern Spars, part of the North Technology Group, is the licensed supplier of the 49er mast. It is a three piece male-moulded assembly made from 100% standard modulus carbon. [9] It is 7.0 metres tall and capable of supporting a combined crew weight up to 165 kg from its dual trapeze. The mast is braced by three sets of shrouds that connect to a fitting on the side of the boat. The crew is able to adjust them by tightening or loosening them, depending on the wind speed and sea states. [10]
The boom is made from an aluminium alloy extrusion.
The rudder and daggerboard are made from a composite of epoxy, carbon and glass, covered by a hard gelcoat surface. The head of each class legal foil carries the embossed 49er logo and the ICA label. [8]
The 49er carries three sails: a mainsail, jib, and spinnaker. The main and jib combined are 20 square metres, fully battened and made of reinforced Mylar (film polyester). The main was redesigned in 2007 from a full, curved roach plan to having a square on top in order to provide more sail area and to control more shape adjustment. The spinnaker is 38 square metres in a tri-radial asymmetric shape. [6]

The 49er FX was developed by Mackay Boats to be a women's Olympic class. It consists of a 49er hull, wings, and foils, with a scaled down rig designed to suit the weight of an elite female crew.
The 29er is a smaller, single trapeze trainer to the 49er. It has become popular in North America, Europe and Australia as a fast youth boat. Recently the 29erXX, a twin trapeze version of the 29er, has been produced with a rig very similar to the 49er.
The 59er dinghy was put into production in Australia and the UK in 2002. It is a non-trapeze, 4.7-metre (15 ft 5 in) sailing dinghy, rigged with an asymmetrical spinnaker. It is designed for a crew weight of 145 to 180 kg (320 to 400 lb).
Dinghy sailing is the activity of sailing small boats by using five essential controls:
The Musto Skiff is a single-handed sailing skiff with a length of 4.55 m. It features a trapeze, asymmetrical spinnaker, wings and low weight and achieves speeds of over 20 knots, which makes it one of the fastest single-handed sailing boats.
The International 505 is a One-Design high-performance two-person monohull planing sailing dinghy, with spinnaker, utilising a trapeze for the crew.
A skiff is any of a variety of essentially unrelated styles of small boats, usually propelled by sails or oars. Traditionally, these are coastal craft or river craft used for work, leisure, as a utility craft, and for fishing, and have a one-person or small crew. Sailing skiffs have developed into high performance competitive classes. Many of today's skiff classes are based in Australia and New Zealand in the form of 12 ft (3.66 m), 13 ft (3.96 m), 16 ft (4.88 m) and 18 ft (5.49 m) skiffs. The 29er, 49er, SKUD and Musto Skiff are all considered to have developed from the skiff concept, all of which are sailed internationally.
The Laser 4000 is a racing dinghy designed by Phil Morrison crewed by two persons. Its one-design weight-equalised system enables physically differing sailors to compete on a level playing field. It is most popular in Europe, particularly the UK, France and Italy.
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 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. 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 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 International 14 is an International racing sailboat, crewed by two sailors. The class was established in 1928.
The 12 ft Skiff is a development dinghy class dating back to the early 20th century. It is sailed in Australia and New Zealand. It is 12 ft (3.7 m) in length, hence the name, and is a two-man boat. Both the crew and the helm are able to use the trapeze at the same time. It has an asymmetrical spinnaker and a jib, in addition to the mainsail.
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 Jacksnipe is a two-man racing sailing dinghy with a single trapeze for the crew and symmetrical spinnaker.
The Phantom is a British sailing dinghy that was designed by Paul Wright and Brian Taylor as a one-design racer and first built in 1971.
The Norfolk Punt is a type of yacht, derived from the flat-bottomed gun punts that roamed the Broadland waters in the mid-to-late 19th century. However, at the turn of the 20th century, in order to get to and from the hunting grounds more quickly, the punters developed their highly unstable craft to carry a basic mast and sail for travelling with the wind. It is from these humble beginnings that one of the country's most exciting and powerful racing dinghy classes was born.
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.
A 16 ft Skiff is a class of three-person sailing dinghy with twin trapezes and a large asymmetrical spinnaker. The class is unique to Australia, where it is one of the most popular boats sailing with 95 boats registered in 12 clubs. The class has the largest fleet of high performance skiffs on the east coast of Australia. Due to the nature of only allowing two trapezes, the age of the sailors can vary between 15 and 60 years old, making it a versatile class of boat.
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 Laser 5000 is a double-handed, dual trapeze skiff with an asymmetrical spinnaker. It derives its name from its length of 5 metres. Losing out to the Bethwaite-designed 49er for selection as an Olympic class for the 2000 Games, it was one of 11 designs that took part in the ISAF High Performance Olympic Dinghy Evaluation Event in 1996.
Julian Bethwaite is an Australian, Sydney-based skiff sailor and sailboat designer. He wrote one chapter of his father Frank's book, Higher Performance Sailing.
