The 49er and 49erFX are high performance, double-handed, Olympic class skiffs. Both use the same hull, with the FX having a slightly smaller rig for women.
The 49er and 49erFX have long been regarded as the most high performance form of Olympic class racing. With foiling classes now nudging into this space, the 49er and 49erFX remain up there as one of the most exciting dinghies to race.
