A proper look-out shall be maintained at what times?

A proper look-out shall be maintained at what times?

• A. Only in congested waters
• B. Only at night
• C. Only during daylight
• D. At all times

Answer: (D)

A continuous, all-the-time duty to observe and listen is what keeps a vessel safe. The rule requires maintaining a proper look-out by sight and hearing, and using all available means appropriate to the conditions, at all times. Hazards, other vessels, navigational marks, and changing weather can appear without warning, and visibility or traffic can vary from moment to moment. Limiting the look-out to night, daylight, or congested waters would create gaps where risks could go unnoticed. That’s why the obligation is to keep a proper look-out at all times.
