The paddle was single-bladed and the same as that used with the second class of Mackenzie Basin canoe (fig. 151). The blade was parallel-sided with the point formed in a short straight-sided ~V~-form; The blade of Yukon paddles was often taper-sided toward the point, which was a rounded ~V~. Other variations in blade form existed, however, and the narrow leaf-shaped blade was used in some areas in Alaska. In the Mackenzie paddles the handle ended in a knob, but in Alaskan versions it ended in a cross-grip like those of paddles used with some Alaskan sea kayaks. The Eskimo double-blade paddle was used with the kayak-form canoe by some paddlers; Hearne mentions its use. Some of the kayak-form canoes were decorated; in Alaska this decoration often took the form of a line of colored beads sewn along each side of the afterdeck at the gunwale, or it consisted of a few oval panels of red, blue, or black paint along the sides or centerline of the afterdeck. In some Mackenzie kayak forms the decks were painted in various designs; a rather common one seems to have been two or more bands of paint around the deck edges, along the gunwales, ending at bow and stern with a full round sweep. Painted disk designs appeared on some of the large Algonkin-Ojibway canoes of the second type. A number of kayak forms became extinct before any accurate, detailed records of their shape and construction had been made; models of some of these canoes exist but are not to scale and are untrustworthy as to detail, since they are often simplified. One model of the extinct British Columbia bateau form, for example, showed but three longitudinals in the bottom, though the probable size of the canoe undoubtedly would have required a greater number. On the other hand, the model may have represented a spruce-bark canoe constructed for temporary use, in which case a simplified construction might have been employed. One can only speculate which it was. Models of some kayak-form Yukon canoes show the decks lashed to the gunwales with a very coarse spiral stitch not recorded for any of the observed full-size canoes; thus it may be a model-maker's method of securing the decking firmly rather than an actual practice used on full-size canoes.
