Q

Which is TRUE concerning reserve buoyancy when flooding occurs in a damaged vessel?

🔍 Key Concepts

• Reserve buoyancy is the volume of a ship above the waterline that can be used to keep the vessel afloat if flooding occurs • Effect of flooding on displacement, draft, and freeboard • Relationship between freeboard (height of deck above water) and remaining watertight volume

💭 Think About

• When compartments flood, what happens to the ship’s draft and freeboard? Think about whether the ship floats higher or lower in the water. • If more water comes inside the hull, does the ship have more or less enclosed, unflooded volume left to support it? • Is reserve buoyancy something that can ‘move sideways,’ or is it mainly about how much intact, unflooded volume remains above the waterline?

✅ Before You Answer

• Be clear on the definition: reserve buoyancy = enclosed watertight volume above the loaded waterline • Consider: as flooding increases, does freeboard increase, decrease, or stay the same? • Ask yourself whether reserve buoyancy is about amount of volume remaining, or about its location (e.g., ‘shifting to the low side’).
