Which term describes the distance from the waterline to the deck on a ship?

Freeboard is the vertical distance from the waterline up to the deck. This measurement shows how much of the hull remains above the water and is a key factor in a vessel’s seaworthiness, helping protect the ship from waves and spray. It also changes with load: taking on cargo, fuel, or ballast lowers freeboard because the waterline rises relative to the deck. For contrast, draft is the distance from the waterline down to the keel, indicating how deep the hull sits in the water. Beam is the ship’s width at its widest point, and the keel is the bottom-most structural line running along the center of the hull.
