Characteristics
Typically 5.0-6.0 metres(16½-21 ft) long and only 40–50 cm (16-20") wide, surf skis are extremely fast when paddled on flat water (only an Olympic K1 or K2 kayak is faster) and the fastest paddled craft available over a long distance on ocean swells. They track well but are less maneuverable and have less transverse primary and secondary stability than shorter, wider craft. Despite its typical instability, a surf ski (with an experienced paddler) is a very effective craft for paddling in big surf. Its narrowness and length helps it cut or punch through large broken waves. Double bladed paddles are used, often with highly contoured wing blades for extra efficiency.
A waveski is a type of short surf ski similar to a surf board, used primarily in surf play. It is usually less than 3 m (10 ft) long, typically with a wide planing type bottom and with one to three fixed skegs, or fins.
