Carling (sailing)
(重定向自Carling knee)
In shipbuilding, carlings are two pieces of timber laid fore and aft under the deck of a ship, from one beam to another, directly over the keel. They serve as a foundation for the whole body of the ship; on these the ledges rest, whereon the planks of the deck, and other structures are fastened. The ends of the curlings are let culvertail into the beams.
