🔍 Key Concepts

• Limber holes and their purpose in ship structure • How water moves to the bilge wells for pumping • The meaning of free surface effect on stability

💭 Think About

• Think about what limber holes actually allow water to do inside the bottom of the ship. • If limber holes are clogged, where will any shipped or leaked water stay, and how could that affect stability? • Which choice best describes the direct consequence of blocked drainage paths, not a change in weight location or area by itself?

✅ Before You Answer

• Identify the primary function of limber holes in double bottoms/frames. • Decide whether clogged limber holes would increase or decrease the free surface effect. • Confirm which option describes a blocked drainage path rather than a stability concept by name.
