While steaming at 14.5 knots, your vessel consumes 319 barrels of fuel oil per day. In order to reduce consumption to 217 barrels of fuel oil per day, what is the maximum speed the vessel can turn for?

Question

Accepted Answer

Option B: 12.8 knots. Applying the inverse cubic relationship from Bowditch to determine maximum speed for reduced fuel: 14.5 × cube root(217 / 319) computes precisely to 12.8 knots.
