Your vessel consumes 215 barrels of fuel per day at a speed of 18.0 knots. What will be the fuel consumption of your vessel at 14.0 knots?

Correct Answer: Option D — 101 bbls

Apply the fuel consumption versus speed cube law from Bowditch: Fuel2 = Fuel1 × (Speed2 / Speed1)^3. Substituting the given values yields 215 × (14.0 / 18.0)^3, resulting in approximately 101 barrels per day, demonstrating the exponential increase in power and fuel required at higher vessel speeds.
