Which term is defined as the backbone of the boat running along the underside from bow to stern?

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

Answer: (B)

The keel is the longitudinal structural element that runs along the bottom of the hull from bow to stern, acting as the boat’s backbone. It provides structural support for the hull, carries ballast in many designs to increase stability, and helps the vessel track straight through the water. The hull is the main body of the boat, the transom is the flat surface at the stern, and the cabin is the enclosed living or working space inside the hull. Because the keel sits along the underside and ties the length of the hull together while contributing stability, it fits the description of the backbone most precisely.
