The development of plastic and rubberized inflatable kayaks arguably initiated the development of freestyle kayaking as we see it today, since these boats could be made smaller, stronger and more resilient than fiberglass boats. Kayaks that are built to cover longer distances such as touring and sea kayaks are longer, generally 16 to 19 feet (4.9 to 5.8 m).

An umiak is a large open sea canoe, ranging from 17 to 30 feet (5.2 to 9.1 m), made with seal skins and wood.The word "kayak" means "man's boat" or "hunter's boat", and native kayaks were a personal craft, each built by the man who used it—with assistance from his wife, who sewed the skins—and closely fitting his size for maximum maneuverability.A special skin jacket, Tuilik, was then laced to the kayak, creating a waterproof seal.Traditional kayaks encompass three types: Baidarkas, from the Bering sea & Aleutian islands, the oldest design, whose rounded shape and numerous chines give them an almost Blimp-like appearance; West Greenland kayaks, with fewer chines and a more angular shape, with gunwales rising to a point at the bow and stern; and East Greenland kayaks that appear similar to the West Greenland style, but often fit more snugly to the paddler and possess a steeper angle between gunwale and stem, which lends maneuverability.Most of the Aleut people in the Aleutian Islands eastward to Greenland Inuit relied on the kayak for hunting a variety of prey—primarily seals, though whales and caribou were important in some areas.Inuit kayak builders had specific measurements for their boats.

The length was typically three times the span of his outstretched arms.

Recreational kayak designers try to provide more stability at the price of reduced speed, and compromise between tracking and maneuverability, ranging from 9–14 feet (2.7–4.3 m).

Primary (sometimes called initial) stability describes how much a boat tips, or rocks back and forth, when displaced from level by paddler weight shifts.

Skin-on-frame kayaks are still being used for hunting by Inuit people in Greenland, because the smooth and flexible skin glides silently through the waves.

In other parts of the world home builders are continuing the tradition of skin on frame kayaks, usually with modern skins of canvas or synthetic fabric, such as sc. Contemporary traditional-style kayaks trace their origins primarily to the native boats of Alaska, northern Canada, and Southwest Greenland.

This enabled the "eskimo roll" to become the preferred method of regaining posture after capsizing, especially as few Inuit could swim; their waters are too cold for a swimmer to survive for long.
