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 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.
