A large ocean-going canoe was carved from a single large cedar log.

The basic hull form was achieved by removing material from both the exterior and the interior of the log, using adzes and other tools to shape the hull to precise dimensions.

The finished hull was then treated with water and steam to make the wood temporarily flexible, allowing the beam of the canoe to be widened by spreading the sides with thwarts.

As the wood dried in this expanded form, it retained the wider beam, producing a hull with better stability than could be achieved from the original log diameter alone.
