← HistoryWhich of these consequences arise when a 1750s-era ship encounters hull barnacle growth beyond acceptable limits?
A)Increased fuel consumption and diminished speed✓
B)Enhanced hydrodynamic efficiency at low speeds
C)Improved ballast and stability
D)Reduced risk of plankton blooms
💡 Explanation
Increased barnacle growth significantly raises the hull's surface roughness, causing increased frictional drag. Wave drag increases; therefore, the ship experiences reduced efficiency, leading to increased fuel consumption and diminished speed, rather than improved performance.
