The two end compartments were entirely covered in, but had openings over which a cover was lashed, and could, if necessary, be used for holding stores; but Godfrey did not intend to put anything here except temporarily, as it was important that the canoe should be as buoyant and light as possible. The frame of the boat was built of the tough and elastic wood of which the Ostjaks made their bows. It was very light, the ribs being bound to the longitudinal pieces by fine gut. It was built, as nearly as Godfrey could lay them out, on the lines of an English cruising canoe. The deck strips were similarly lashed, and when the framework was completed Godfrey tested its strength by dropping it three feet to the ground, rolling it over and over, and trying it in a variety of ways. When fully satisfied with it the work of putting on the cover commenced. This was made of very soft and well-tanned reindeer hide, stretched as tightly as possible, and then rubbed with seal oil. The keel of the boat had been made very strong, as the rigidity of the whole craft depended upon this. It had been made flat, and the skins had been taken over it. When it was finished a false keel six inches in depth in the centre, tapering away to nothing at the ends, was fixed underneath. This keel was also made of tough wood, a little more than a quarter of an inch thick, but widening suddenly to over an inch where it touched the boat, in order that it might be securely fixed with screws to the keel inside. The boat was provided with a light mast, which could be stepped or unstepped at pleasure, and there were two stays of twisted leather, one fastening to each side of the boat. An iron ring with a cord travelled up and down the mast, the halliard running through a small block, as Luka had been able to obtain a sheave at Turukhansk. The sail was a lug made of sheeting, oiled, and the boat carried beside a triangular sail of very much smaller dimensions and stouter cloth for heavy weather. She also carried a small mizzen mast and sail. In rough weather the cockpit could be completely covered with a light apron with openings where the rowers sat, with a sort of collar, which could be lashed tightly round their waists. The edges of this apron could be lashed down over the gunwale round the cockpit. When completed the canoe itself, with its mast and sails, weighed but sixty pounds, and could be carried with ease by one person on his shoulder.
