Wind acts upon which portion of a vessel that is above water?

• A. Keel
• B. Freeboard
• C. Hull bottom
• D. Propeller

Answer: (B)

Wind acts on the portion of a vessel that is above the water—the freeboard. This refers to the parts of the hull and any decks or superstructure that rise above the waterline and are exposed to air. Those above-water surfaces catch the wind and experience wind pressure and drag, which can affect stability and handling. The keel, hull bottom, and propeller are mostly or entirely underwater and are not directly subjected to wind in the same way.
