While steaming at 17.0 knots, your vessel consumes 382 barrels of fuel oil per day. In order to reduce consumption to 223 barrels of fuel oil per day, what is the maximum speed the vessel can turn for?

Correct Answer: Option A — 14.2 knots

Using the fuel-speed cubic law outlined in Bowditch to solve for reduced consumption velocity: 17.0 × cube root(223 / 382) yields a maximum allowable speed of 14.2 knots.
