Transom

A transom is the horizontal crossbar or panel that sits above a door or window opening, dividing the frame into sections. It can be a simple structural element, or it may contain a window itself, allowing light and air to pass through while maintaining the integrity of the wall. In boats, a transom refers to the flat surface at the back that provides structural support for the motor and helps shape the boat’s hull. Overall, transoms serve both functional and aesthetic purposes in architecture and design, contributing to stability, ventilation, and visual appeal.
