Rule 5 Lookout requirement ensures a proper lookout by which means?

• A. Sight and hearing, using all available means
• B. Visual only
• C. Radar only
• D. Echolocation

Answer: (A)

A proper lookout means using sight and hearing together with all available means appropriate to the circumstances. You don’t rely on eyes alone; you continuously scan visually while listening for sounds of other vessels, engines, bells, or radio communications, and you bring in equipment like radar, AIS, and other sensors to detect and evaluate potential hazards. This integrated approach is essential, especially in poor visibility or busy water, because it allows you to identify risks early and take timely action to maintain safe navigation. The other options limit how you gather information—visual only ignores sound and tools; radar only misses the human senses; echolocation is not a standard maritime resource.
