🔍 Key Concepts

• Buoyancy as the upward force due to displaced water • Difference between flooded spaces and intact (dry) spaces • How remaining watertight volume affects a ship’s ability to stay afloat after damage

💭 Think About

• Ask yourself: Is intact buoyancy about spaces that are already flooded, or spaces that are still dry and helping the ship float? • Consider which choice best reflects the total volume that can still provide upward support if the ship is damaged. • Think about whether intact buoyancy refers to a specific point on the ship, or to a collection of spaces/volume.

✅ Before You Answer

• Eliminate any option that clearly involves spaces already flooded as part of the buoyancy definition. • Check whether the option talks about volume/space contributing to flotation, not about forces being concentrated at a single point (that’s a different concept). • Verify that the description matches something that helps the vessel continue to float if lower spaces are damaged or flooded.
