Each individual plank (majèr) was cut-out from the larch dimensional lumber - these should have a minimum number of knots and should be at least 16'5" long to avoid the need to join planks lengthwise. A very important feature of the dimensional lumber is the width - we needed a broader lumber, since the boat sides were curved and the planks were therefore cut in the arc. The most intricate stage of plank-making was their bending using propane burner. Larch is a very elastic wood and tends to return to its initial position, so we had to bend it 50% excessively. However, they weren't required to remain curved to the final extent - when there were a need we forced the plank to remain in a desired shape with F clamps.
