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.
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.
To handle a large and powerful sail area, the mast uses a square topped sail that causing 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.
