Transom (nautical)

A transom is the aft transverse surface of the hull of some boats and ships forming its stern. Adding both strength and width to the stern, a transom may be flat or curved, and vertical, raked aft, or raked forward. In small boats and yachts, a flat termination of the stern is typically above the waterline, but large commercial vessels often exhibit vertical transoms that dip slightly beneath the water.
On smaller boats such as dinghies, transoms may be used to support a rudder, outboard motor, or other accessory. On some yachts the transom may include a hinged swim platform, and a lazarette for deck items and leisure toys.

Etymology

The term was used as far back as Middle English in the 1300s, having come from Latin transversus via Old French traversain.
