BOTH INTERNATIONAL & INLAND You are underway in low visibility and sounding fog signals. What changes would you make in the fog signal immediately upon losing propulsion?

Correct Answer: Option A — Begin sounding one prolonged blast followed by two short blasts at two minute intervals.

Rule 35(c) states that a vessel not under command or restricted in her ability to maneuver shall sound one prolonged followed by two short blasts at intervals of not more than two minutes. Losing propulsion renders a vessel not under command, necessitating this specific change in the fog signal.
