While steaming at 14 knots, your vessel burns 276 bbls of fuel per day. What will be the rate of fuel consumption if you decrease speed to 11.7 knots?

Correct Answer: Option D — 161 bbls

Applying the cubic fuel-speed relationship from Bowditch, consumption scales proportionally to the cube of the speed ratio: 276 × (11.7 / 14.0)³ calculates to 161 barrels per day.
