Safe speed is defined as that speed where you can take proper and effective action to avoid collision.

• A. The Maximum Speed Allowed by Law
• B. The Speed of Other Vessels
• C. A Speed That Allows Proper Action to Avoid Collision
• D. The Speed You Can Maintain for a Long Voyage

Answer: (C)

Safe speed is the speed at which you can take proper and effective action to avoid collision, given the current conditions. It means choosing a pace that leaves you enough time and space to react if another vessel behaves unexpectedly, if a hazard appears, or if visibility, weather, or traffic changes. You’re not aiming for the highest possible speed or for the speed of others; you’re aiming for a speed that lets you safely maneuver or stop in time to prevent a collision. In practice, this means slowing down in poor visibility or dense traffic, or when maneuverability is reduced, and adjusting as conditions improve. The other options miss the point: a legal maximum is just a constraint, not the definition of safety; the speed of other vessels isn’t your own operating speed; and the long-voyage speed relates to efficiency, not collision avoidance.
