Which term describes the vertical surface at the stern that spans the width and is commonly used to mount outboard motors?

• A. Gunwale
• B. Keel
• C. Hull
• D. Transom

Answer: (D)

The transom is the flat, vertical surface at the stern that spans the boat’s width and provides a mounting point for outboard motors. It’s specifically designed to handle the engine’s mounting bolts, thrust, and vibration, often reinforced to support the motor attachment and transfer loads into the hull. The gunwale is the upper edge along the sides, the keel runs along the bottom centerline, and the hull is the entire main body of the boat—none of these describe the back surface used for mounting an engine.
