Your vessel consumes 156 barrels of fuel per day at a speed of 13.0 knots. What will be the fuel consumption of your vessel at 16.0 knots?

Correct Answer: Option D — 291 bbls

Fuel consumption follows the cubic law: F2 = F1 * (V2/V1)^3. With V1=13, F1=156, and V2=16, the calculation (16/13)^3 * 156 equals approximately 291 barrels. This formula is essential for voyage planning and fuel management, reflecting the power required to overcome hydrodynamic resistance at varying speeds.
