🔍 Key Concepts

• Enclosed lifeboat design and stability (how they are built to self-right) • Weight and buoyancy distribution between top and bottom of the boat • The purpose of permanent ballast in survival craft

💭 Think About

• Which feature would make the bottom of the lifeboat heavier than the top so it wants to end up upright? • Which option is a built‑in, always-present design feature, rather than something that depends on what people do during an emergency? • Think about what would still be true even if the boat were empty, with no people on board.

✅ Before You Answer

• Identify which answer choice involves a fixed weight low in the hull rather than a temporary or variable condition • Ask: does this choice affect stability or just comfort/operations? • Check which factor would still work to right the boat even if nobody could take any action during the capsize
