🔍 Key Concepts

• Reserve buoyancy relates to how much of the ship’s enclosed volume is still available to provide flotation if the vessel is loaded or flooded • Think about the waterline: some parts of the ship are above it, some below it • Consider the difference between stability measures (like metacentric height) and buoyancy/volume concepts

💭 Think About

• Which choices describe a volume of enclosed, watertight space rather than a structure or a stability measurement? • Does reserve buoyancy deal with how the ship resists capsizing, or how much additional flotation capacity it has if pressed deeper into the water? • Look at the words "above" and "below" the waterline in the options: which location makes sense for extra flotation available in an emergency?

✅ Before You Answer

• Identify which options refer to enclosed, watertight volume rather than to a structural component or a stability term • Ask: reserve buoyancy must be unused buoyant volume at the vessel’s normal load condition – which option matches that idea? • Eliminate any options that clearly describe transverse bulkheads or metacentric height, since those are different concepts from reserve buoyancy
