Which board is attached to the side of the hull?

• A. Centerboard
• B. Daggerboard
• C. Leeboard
• D. Keel

Answer: (C)

Leeboards are boards mounted on the sides of the hull to provide lateral resistance and reduce leeway when sailing, especially on shallow-draft boats without a fixed keel. They are lowered into the water on the leeward side as the boat heels, helping the boat stay on course by resisting sideways slip. Centerboards and daggerboards are designed to run through the hull along the centerline—one retractable in a trunk, the other sliding through the deck—so they are not attached to the sides. A keel is a fixed underwater fin on the bottom of the hull and isn’t on the sides either. So the board attached to the side of the hull is the leeboard.
