Events Olympics Men's 49er Women's 49er FX World Championships Men's 49er Women's 49er FX Related boats 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, 4.7m (15 feet 5 inches) sailing dinghy, rigged with an asymmetrical spinnaker. It is designed for a crew weight of 145 kg to 180 kg (320 lb to 400 lb). References External links International 49er Class Association UK 49er Class Association ISAF 49er Microsite
