Which element runs along the underside of the boat from bow to stern along the centerline?

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

Answer: (A)

The element being described is the keel. It runs along the underside of the boat, along the centerline from the bow to the stern, forming a structural and ballast-bearing spine. The keel’s main roles are to provide ballast to lower the boat’s center of gravity for stability and to help the boat track straight through the water, resisting sideways drift. Think of the hull as the entire outer body of the boat, while the bilge is the lowest interior area where water tends to collect, and the cabin is the living space above deck. The keel is the specific underwater component that runs along the centerline.
