Your vessel consumes 199 barrels of fuel per day at a speed of 14.5 knots. What will be the fuel consumption of your vessel at 10.0 knots?

Correct Answer: Option C — 65 bbls

Fuel consumption is proportional to the cube of the speed (C1/C2 = V1³/V2³). Given 199 bbls at 14.5 knots, the consumption at 10.0 knots is calculated as 199 * (10/14.5)³. This results in approximately 65 barrels per day, adhering to standard marine engineering fuel consumption laws.
