🔍 Key Concepts

• Difference between light displacement, heavy displacement, and what is included in each • What items (fuel, water, stores, cargo) are counted as deadweight versus part of the light ship • Setting up a simple subtraction to find cargo capacity from total loaded condition

💭 Think About

• First, think about what the heavy displacement represents for this vessel and what is already included in that number when the ship is fully loaded. • Ask yourself: which weights given in the problem are not cargo, but still part of the ship’s loaded condition? • Once you know total loaded weight and you subtract all the non‑cargo items (including the light ship), what is left over for cargo?

✅ Before You Answer

• Be clear on the definition: light displacement is the ship itself without fuel, water, stores, or cargo. • Confirm that heavy displacement here means the displacement when the ship is fully loaded with fuel, water, stores, and cargo. • Before picking an answer, calculate: cargo capacity = heavy displacement − light displacement − (fuel + water and stores) and check that your arithmetic matches one of the choices.
