🔍 Key Concepts

• Difference between draft and freeboard • What part of the ship is measured from the keel (bottom of hull) • How reserve buoyancy and tonnage relate to volume, not a simple vertical distance

💭 Think About

• Ask yourself: is the question asking about the distance measured above the waterline or below the waterline? • Which choice is defined as the vertical distance from the keel (bottom of the hull) up to the waterline? • Which terms describe capacities or volumes of the vessel rather than a specific linear measurement?

✅ Before You Answer

• Identify which terms are vertical distance measurements and which describe volume or capacity • Focus on the phrase "bottom of the hull"—that’s usually the keel • Confirm whether the correct term is measured from waterline upward or from keel up to the waterline
