Hulls of larger drua were planked by a Samoan method, apparently introduced into Fiji by Tongan sponsored Samoan specialists, the Lemaki. The outside of the planks was smooth, ridges were left upstanding throughout the inside edges. Converging holes were drilled through the ridges of adjacent planks so that they met within the wood. Magimagi (coconut husk fibre) cord could then be passed through these holes to lash the planks tightly together. Before being tied, strips of barkcloth smeared with heated breadfruit gum were squashed between the planks to seal the joints.
