A proper look-out must be kept __________.

Keeping a proper look-out at all times is crucial for navigational safety. This practice ensures that a vessel can effectively monitor for other vessels, potential hazards, navigational aids, and any sudden changes in operating conditions. A vigilant look-out allows crew members to react promptly to any unexpected situations, thereby helping to prevent collisions and ensuring the safety of all onboard.

Merely keeping a look-out during specific times or conditions—such as in fog, at night, or during port maneuvers—does not provide comprehensive safety coverage. Dangerous situations can occur at any time, and a constant watch mitigates risks by maintaining awareness of the environment and surrounding vessels, no matter the circumstances. This continuous vigilance is a fundamental responsibility of the crew, emphasizing the importance of situational awareness in boating operations.
