🔍 Key Concepts

• Structural members in the bottom of the ship • How spaces are formed around double bottoms and tanks • Difference between living spaces, machinery spaces, and structural areas

💭 Think About

• Think about where liquid cargo or ballast might be held and what parts enclose those spaces. • Ask yourself: which area of the ship needs special structural plates along the turn of the bilge? • Consider which part of the ship uses terms that sound like they relate to tank boundaries rather than living or working spaces.

✅ Before You Answer

• Identify which choice is most closely related to double-bottom construction. • Eliminate any answers that are clearly accommodation spaces or mainly for crew comfort. • Check which area would logically have both a plate forming the boundary of a tank and something sometimes called a "ceiling" even though it is actually on the bottom structure.
