The thwarts, spaced equal distances apart, were tenoned into the gunwales as in the old Malecite canoes, and were secured with a peg and lashing through the two holes in the thwart ends. The middle thwart was usually formed with a shoulder, viewed in plan, that started 6 or 7 inches inboard of the inside face of the main gunwale. In form, this thwart usually swelled outward in a straight line from the tenon shoulder, then reduced in a curved line to about the width of the tenon tongue and, finally, increased again in a right-angle cut to the greatest width. From here it was reduced again in a long curve to the canoe's center line. The other thwarts usually had simple ends, wide at the tenon shoulder and reduced in a long curve to a narrow center. In elevation, all the thwarts were thin outboard and thick at the centerline of the canoe. The cross section of the center thwart at the centerline was square or nearly so, the first thwart on each side was rectangular in cross section at the center, and the end thwarts were similar, but very thin. The sheathing of the Têtes de Boule canoes was thin, particularly at the ends of the strakes. The bottom was laid with a parallel-sided center strake going in first. This strake was in two lengths in a small canoe and three lengths in a large, the butts overlapping slightly. The rest of the strakes in the bottom were tapered toward the ends of the canoe. At the extremities of the canoe, the narrow ends of the strakes were very thin and overlapped along their edges, the bottom sheathing, when in place, thus following the diamond form of the building frame. The topside sheathing was laid up in short lengths with overlapping butts and edges in an irregular plan, those strakes along the bilges being longer than above. Toward the ends of the canoe these strakes were slightly tapered and the edges were very thin. The sheathing ended irregularly, outboard of the headboards, in narrow butts as in most eastern canoes.
