If a vessel hears a fog signal forward of her beam and has not determined whether a risk of collision exists, what speed should she reduce to?

• A. Bare steerageway
• B. Dead slow
• C. Half speed
• D. Full ahead

Answer: (A)

In restricted visibility, if you hear a fog signal forward of your beam and you haven’t determined whether there’s a risk of collision, you should drop to the minimum speed that still allows steering and maneuvering—bare steerageway. This speed keeps your rudder effective and gives you the greatest ability to observe, assess, and take evasive action if another vessel is present. Going faster would reduce your reaction time and limit options, while stopping completely or moving at a higher speed would not provide the necessary control in case a vessel suddenly appears. Dead slow, half speed, or full ahead would not meet the need to preserve maneuverability and readiness for action, so bare steerageway is the best choice.
