Instead of a tuilik, most traditional kayakers today use a spray deck made of waterproof synthetic material stretchy enough to fit tightly around the cockpit rim and body of the kayaker, and which can be released rapidly from the cockpit to permit easy exit.
Inuit kayak builders had specific measurements for their boats.
Aleut: Iqyax) were originally developed by the Inuit, Yup'ik, and Aleut.
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.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.This section may require cleanup to meet Wikipedia's quality standards.The specific problem is: references need improving, globalization needed (nothing on the dory-shaped East Arctic kayaks, for example), expert needed.The paddler wore a tuilik, a garment that was stretched over the rim of the kayak coaming, and sealed with drawstrings at the coaming, wrists, and hood edges.
This enabled the "eskimo roll" and rescue to become the preferred methods of recovery after capsizing, especially as few Inuit could swim; their waters are too cold for a swimmer to survive for long.His PFD is also large enough to slip off over his head while fastened.Typically, kayak design is largely a matter of trade-offs: directional stability ("tracking") vs maneuverability; stability vs speed; and primary vs secondary stability.Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull by twin hulls, and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and "flippers".Kayaks are also being sailed, as well as propelled by means of small electric motors, and even by outboard gas engines.These first kayaks were constructed from stitched seal or other animal skins stretched over a wood or whalebone-skeleton frame.
