Which would NOT provide extra buoyancy for a vessel with no sheer?

🔍 Key Concepts

• Buoyancy and reserve buoyancy – what actually makes a hull float and stay afloat • Sheer, poop, and fo'c'sle head – how vertical curvature and raised ends affect reserve buoyancy • Difference between watertight enclosed volume and open structures like bulwarks

💭 Think About

• For each choice, ask: does this create additional watertight volume above the waterline that could keep the ship afloat if she were pressed down? • Think about why ships have raised forecastles and poops on older designs – what problem are they solving compared to a flush deck? • Consider what happens structurally and hydrostatically when you make the draft lighter versus when you raise parts of the deck or side plating.

✅ Before You Answer

• Identify which options actually add enclosed, watertight volume at the ends of the ship (important for reserve buoyancy). • Check whether a lighter draft changes how much of the existing hull volume is submerged versus reserved above water. • Ask yourself if a higher bulwark is normally a watertight structure that counts as enclosed hull volume, or mainly a crew/weather protection feature.
