Abstract: A boat hull (10) and its method of construction are dislosed. The hull (10) is formed on an inner layer (12) comprised of a plurality of longitudinally extending planks (16) and an outer layer (14) comprised of a plurality of longitudinally extending planks (18). A groove (24) is formed in the outwardly facing surface of the planks (16). A cord 26 is fitted in the groove 24. An adhesive is applied into the groove (24) in such a manner that the adhesive penetrates the groove (24), passes into the interior of the cord (26) and into the pores or capillary spacing of the wood of the planks (16) in the area surrounding the groove (24). Planks (18) of the second layer (14) are attached to the outwardly facing surface of the first planks (16).
