A right-angled timber or metal bar used for strengthening and for support at the points of intersection of ship's timbers in a wooden ship. They are of various kinds, such as a hanging knee, which fits vertically under a deck beam and supports its ends; a lodging knee, which is fixed horizontally between the forward side of a beam and the ship's side; a bosom knee which performs the same purpose on the after side of a beam; and a carling knee, which strengthens the right angle between a carling and a beam. Knees of ships' boats, which support the thwarts, or in small sailing craft, which support the deck beams, are preferably fashioned from naturally grown timber in which the grain of the wood follows the right angle round. In the days of sail trees used to be artificially bent during growth to provide knee-timber for shipbuilding.
