- Surf ski
A surf ski is a long, narrow, lightweight
kayakwith an open (sit-on-top) cockpit, usually with a foot pedal controlled rudder.
Typically 5-6.5m (16½-21ft) long and only 40-50cm (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.
waveskiis a type of short surf ski similar to a surf board, used primarily in surf play. It is usually less than 3m (10ft) long, typically with a wide planing type bottom and with one to three fixed skegs, or fins.
Surf skis are used worldwide for
surf lifesaving, surf kayaking and for training and competition on flat-water or ocean racing. They are most popular in warmer coastal regions such as Australia, California, Hawaii, and South Africa, as paddling a surf ski inevitably involves contact with the water. In cooler waters, paddlers often choose to wear a wetsuit.
Construction and design
Some cheaper, heavier surf skis are made from polyethylene. Light weight surf skis are made of composite layers of epoxy or polyester resin-bonded cloth:
fibreglass, kevlar, carbon fibreor a mixture. To cut weight, the number of layers of the material and the amount of resin may be minimised to just that necessary for structural integrity or increased for extra strength and durability in heavy surf.
Early surf skis were constructed in the same way as early surfboards, being laminated from light wood and sometimes covered with fabric. In the 1960s, the first foam surfboards and surf skis were carved from a single block of
expanded polystyrenefoam, strengthened with wooden stringers and covered with a thin layer of fibreglass. As the demand for surf skis grew in the 1970s, this custom method of production proved too costly and moulds were made from the most successful surf skis so that moulded craft could be made more cost effectively out of glass-fibre. At the same time, there was a divergence in ski design, one type becoming known as the lifesaving specification surf ski (spec ski) and the other being the long distance or ocean racing surf ski.
Ocean racing surf skis differ from spec skis in that they are longer, have sharply pointed bows and under stern rudders. The front of the modern lifesaving type surf ski is often flared to prevent nose diving on returning to shore when surfing down large steep waves. Ocean racing surf skis are also usually longer than long distance racing kayaks; they have more longitudinal curvature (rocker); they typically have less transverse primary and secondary stability but more longitudinal stability because the paddler is seated more towards the centre of the craft to enhance wave riding ability. An ocean racing surf ski must have enough volume in the bow to provide buoyancy when punching through surf, a long waterline to make use of ocean swells, a sleek, narrow shape to reduce water resistance, as well as enough stability to make paddling in rough conditions feasible.
The spec ski is used in
surf lifesavingcompetitions in Australia, Canada, New Zealand, South Africaand the USA. Since its introduction, surf ski racing has been managed by the International Life Saving Federation. The standard ILS surf ski race is about 700m, from a start in the water, out around a series of buoys and back to the beach.

It was not long before people began going further afield in these new, extremely seaworthy craft, and ocean racing began to emerge. The earliest races were the Scottburgh to Brighton in
South Africa, a 46km event first held in 1958; the Port Elizabeth to East London in South Africa, a 240km event held every two years since 1972; and the most famous of them all, the Molokairace in Hawaii, a 60km event first held in 1976.
More recently, there has been a huge growth in ocean surf ski racing in mainland USA, Australia, New Zealand and other Pacific countries. There has been a move in many of these active surf ski racing countries to transfer the ocean events to the
International Canoe Federations as the Lifesaving Federations often do not have the resources to manage long distance races with up to 500 competitors.
As well as ocean racing, surf skis are becoming increasingly popular as a versatile racing craft for open class races that take place in sheltered bays, lakes and rivers. One advantage of the surf ski over the traditional kayak is that if the conditions tip the paddler into the water, a "wet entry" is possible by simply climbing back onto the boat and continuing paddling without first having to drain the boat of water.

The earliest reports of surf skis originate from
Newcastle Beachin Australiain the 1920s, though other accounts are reported from South Africa. Surf skis were originally designed to be paddled out through surf in order to rescue drowning swimmers. Until the 1960s, surf boats -- lightweight rowing boats with a crew of five -- were responsible for the rescue work in and behind the surf line. These boats were expensive and require a huge amount of skill to be used effectively. It was soon realised that a double surf ski could do almost everything that a surf boat could do, and in 1946the importance of surf skis was noted by the surf lifesaving associations and they were included in lifesaving competitions and championships. Riders could stand up on them to surf them back to shore. These early surf skis were very wide and bear little resemblance to their modern counterparts. Surf skis were quickly introduced into surf lifesaving as a competition event. Over time they became narrower to maximise speed.
In 1984, waveski surfing became established as an offshoot of surf skiing with the formation of the World Waveski Surfing Association.
