- 1.1Each of a set of short bars that engage with the whelps and prevent a capstan, windlass, or winch from recoiling.‘The capstan for raising the anchor was something I hadn't seen before - like a huge rolling pin set across the ship, with wooden pawls to prevent backwards rotation.’‘In the tang of a gathering sea breeze, listening to the click of pawls as winches spun, all the Machiavellian intrigue faded.’
