Navigation Rule 5 says every vessel must keep a proper lookout using what?

Sight, hearing and all available means.

  1. Sight, hearing and all available means ✔
  2. Radar only
  3. GPS alerts only

Why: Rule 5 requires a proper lookout at all times by sight and hearing plus all available means, so you can fully judge the situation and the risk of collision.

Huh, didn't know that: The Coast Guard guide says most boating accidents are caused by operator inattention.
