The Koryak kayak is a hunting boat well designed for use in protected waters, but is rather weakly built. In general form it is much like the hunting and fowling skiffs formerly used in America. The plan idealizes the kayak somewhat, for the boat is crude in finish. The only example available for study, in the American Museum of Natural History, is in poor condition. The hull is short, wide and shallow, rather ~V~ in cross section, and there is a slight camber in the deck. The length of the Koryak kayak rarely exceeds 10 feet, the beam is from 24 to 26 inches, and the depth between 8 and 9½ inches. The manhole rim is of large diameter, high and without rake. The gunwales, although rather slight, are the strength members. The keelson, a thin, flat batten, forms the stem and stern posts; it is stiffened amidships by a short batten lashed inside the frames. The chine battens are also slight and do not reach the stem and stern. The frames are widely spaced and are wide and thin, in one piece from gunwale to gunwale. There are but two thwarts; these are strong and support the manhole rim, showing inside the cockpit. Two thin longitudinal battens afore and abaft the manhole, support the deck, in addition to a light centerline ridge-batten. On the kayak illustrated the outboard battens appear to have had additional support at one time from two pairs of stanchions standing on frames at the chines, with their heads secured to the deck battens; a pair being placed before and abaft the manhole. A small plank seat appears to have been used and the boat was propelled by two short one-hand paddles, secured to the manhole rim by lanyards made of thongs; these would be only efficient in smooth water. The cover is made from bearded seal skins and passes under the manhole rim being sewn to the rim on the inside at the top, by coarse sewing passed through holes bored in the manhole rim. There are two thong lifting handles or loops, one at bow and stern. This kayak is the most primitive of all types and the smallest as well. The Koryaks are not daring canoemen and do not venture into rough water. Nevertheless, this type of kayak is said to be fast and highly maneuverable.
