Why is early action emphasized in Rule 8?

• A. To punish reckless vessels.
• B. To avoid using radar.
• C. To allow vessels to pass faster.
• D. To reduce the chance of sudden, dangerous maneuvers and near-misses.

Answer: (D)

Early action to avoid a collision means acting promptly when a risk is detected, so there’s time to assess, communicate, and adjust course or speed before the situation becomes urgent. Rule 8 requires taking early and substantial action to prevent collisions, using all available means. If action is delayed, maneuvers tend to become abrupt and less predictable, increasing the chance of dangerous changes and near-misses for both vessels. By acting early, you maintain safer separation and give the other vessel time to respond, which directly lowers the risk of sudden, dangerous maneuvers and close calls.
