🔍 Key Concepts

• Archimedes’ principle and how it relates to a floating vessel • The meaning of displaced water in naval architecture • Difference between forces acting on a vessel vs. simple measurements (like draft/freeboard)

💭 Think About

• Ask yourself: which option names a force or effect caused by the water pushing up on the ship, rather than a weight or a distance? • Consider which terms refer to vertical measurements on the hull (from keel to waterline, or waterline to deck) and rule those out if the question is asking about an upward pressure. • Think about what keeps a ship from sinking: is it its deadweight, its draft, its freeboard, or another concept related to displaced water?

✅ Before You Answer

• Identify which choice is directly tied to the upward force from the water on the vessel. • Eliminate any term that is just a linear measurement (in feet or meters) on the ship’s side. • Eliminate any term that primarily refers to the weight of cargo + fuel + stores the ship can carry.
