Question 1 of 27070

🔍 Key Concepts

• Meaning of lightweight vs. deadweight in stability/trim calculations • How permanent structural or equipment changes are accounted for before they are officially included in the vessel’s approved lightweight • Difference between variable loads (cargo, fuel, stores, people) and loads treated as part of the ship’s constant weight

💭 Think About

• Ask yourself: Are these changes to lightweight being treated as something that comes and goes each voyage, or something that is effectively always on board? • Consider which type of load you would use when updating stability calculations before a formal lightweight survey is approved. • Think about which of these four choices is actually used in the context of hydrostatic and stability manuals, rather than tonnage measurement or regulatory paperwork.

✅ Before You Answer

• Verify how your stability book defines lightweight, constant ship’s weight, and variable loads. • Check which of the options refers to items that are assumed to be always present for stability calculations, even if not yet in the official approved lightweight. • Confirm that gross tonnage is a volume-based measurement, not a weight and center of gravity item in the stability sense.
