, or crotch.
A support fixed upon the taffrail for the main boom of a sloop, brig, cutter, &c., and a chock for the driver-boom of a ship when their respective sails are furled. Also, crooked timber inside the after-peak of a vessel, for securing the heels of the cant or half-timbers: they are fayed and bolted on the foot-waling. Also, stanchions of wood or iron whose upper parts are forked to receive masts, yards, and other spars, and which are fixed along the sides and gangways. Crutches are used instead of rowlocks, and also on the sides of large boats to support the oars and spars.
