These kayaks are highly developed craft--stable, fast, and seaworthy--and the construction is light yet strong enough to withstand the severe abuse sometimes given them. The cap on the fore part of the manhole is a paddle holder, for resting the paddle across the deck. Some Eskimos used this as a thole, and when tired, "rowed" the kayak with the paddle, to maintain control. It will be noted that oval or circular manholes are seldom found in the eastern types of kayaks already described; ~U~-shaped manholes, or bent-rim manholes approaching this form, appear in those very stable types which do not require to be righted at sea by the paddler and in which the watertight paddling jacket or waistband is not used. Farther south, on the northern coast of Greenland, and apparently also on the opposite coast of Baffin Island, a modified design of kayak is used. This type, illustrated in figure 205, shows relationship to both the flat-bottom kayak of northern Greenland and to the northeastern Labrador type. In this model the "clipper" bow is retained but the stern and cross section resemble those of the Labrador kayaks. The construction, however, is fundamentally that employed in northern Greenland. As in the Labrador type, the deadrise in the bottom is formed by using in the keelson members that are deeper than those in the chine. The gunwales do not flare as in the Greenland model, but stand vertical in the side flaring slightly at bow and extreme stern. The frame heads are rather loosely tenoned and are commonly secured to the gunwales with lashings. Transverse stiffness is obtained in this model by employing a rather heavy, rigid keelson fixed to the stern block, and by a tripod arrangement forward consisting of the stem batten and a pair of transverse frames placed at the junction of stem and keelson with their heads firmly lashed and tenoned into the gunwales. The construction, though strong, is rather rough compared to that of other Greenland types. The manhole rim in this type is not bent, but is made up of short straight pieces, as shown in the drawing; and the double-bladed paddle shown resembles that used in Labrador. This is a rather heavy kayak of very good qualities but not as maneuverable as some of the flat-bottom kayaks found farther north.
