Transom (nautical)

From Wikipedia, the free encyclopedia
Vertical transom and stern of a modern cargo ship

A transom is the vertical reinforcement which strengthens the stern of a boat.[1] This flat termination of the stern is typically above the waterline.[2]

The term was used as far back as Middle English in the 1300s, having come from Latin transversus (transverse) via Old French traversain (set crosswise).[1]

The stern of a boat is typically vertical. It can be raked such that there is an overhang above the water, as at the bow. A reverse transom is angled from the waterline forwards.[3]

Transoms can be used to support a rudder, outboard motor, or as a swimming and access platform.[4]
