Your vessel consumes 216 barrels of fuel per day at a speed of 15.0 knots. What will be the fuel consumption of your vessel at 17.5 knots?

Correct Answer: Option B — 343 bbls

Fuel consumption varies proportionally with the cube of the vessel's speed according to naval architecture principles. Using the fuel law formula: F2 = F1 * (V2 / V1)^3, substitute 216 bbls * (17.5 / 15.0)^3, which yields a daily consumption of 343 barrels.
