1 The athwartship timbers bolted to the sternpost of a ship to give it a flat stern. In the older square-rigged ships, particularly men-of-war, they were usually rather heavier than other timbers in order to support the overhang of the stern and quarter galleries. In modern vessels there is no overhang with a transom stern, and in consequence no need for the stern timbers to be heavier than any others.
2 A name often given to the vane of a cross-staff, that part which slid along the staff by means of a square socket cut in the centre of the vane.
3 The cross-piece of timber which connected the cheeks of a wooden gun carriage during the days of sailing navies.
