Which describes Safe Speed?

• A. The vessel should always travel at its maximum engine speed.
• B. The vessel should proceed at a speed that allows proper and effective action to avoid collision and to stop within a distance appropriate to the circumstances.
• C. The vessel should never slow down even if other vessels are near.
• D. Safe speed is the same as the speed of the vessel ahead.

Answer: (B)

Safe speed is a flexible, situational speed chosen so you can take proper and effective action to avoid a collision and stop within the distance appropriate to the current circumstances. It isn’t a fixed number or the vessel’s maximum speed; it depends on visibility, traffic density, maneuverability of all vessels involved, weather and sea state, currents, depth, and any navigational hazards. In poor visibility, heavy traffic, at night, or in congested areas, you’re expected to slow so you can observe, anticipate actions by others, and respond quickly if needed. The point is to remain able to alter course or reduce speed to prevent a collision, not to maintain a particular speed. Choosing to sail at maximum speed or to match the vessel ahead does not guarantee safety, because safe speed must reflect what you can safely do given the prevailing conditions.
