  1. When operating in heavy boat traffic, what is the safest speed to maintain?

    Answer: The minimum speed needed to maintain steerage and control

    The minimum speed needed to maintain steerage reduces the risk of collision and gives you more time to react to hazards.

  2. A boat is overtaking you from behind on your starboard side. Who has the right of way?

    Answer: You, the vessel being overtaken, have the right of way

    The vessel being overtaken is the stand-on vessel and has right of way; the overtaking vessel must keep clear.

  3. What does a defensive boater do when visibility drops due to fog?

    Answer: Reduce speed, sound fog signals, and post a lookout

    In restricted visibility, operators must reduce speed, use appropriate sound signals, and keep a proper lookout.

  4. When approaching a blind bend in a narrow channel, a defensive boater should:

    Answer: Sound one prolonged blast and proceed cautiously on the starboard side

    One prolonged blast signals your presence around a blind bend, and hugging the starboard side follows the rules for narrow channels.

  5. Which action best demonstrates defensive boating when another vessel is acting unpredictably?

    Answer: Slow down, give wide berth, and be prepared to stop

    Creating distance and reducing speed when another vessel is unpredictable maximizes your reaction time and safety margin.

  6. What is the primary reason to avoid operating a boat while fatigued?

    Answer: Fatigue impairs judgment, reaction time, and situational awareness

    Fatigue degrades the mental and physical abilities needed for safe boat operation, similar to alcohol impairment.

  7. When crossing a busy shipping lane, the safest approach is to:

    Answer: Cross as rapidly as possible at a right angle to the lane

    Crossing shipping lanes at a right angle minimizes the time your vessel is exposed to large, fast-moving commercial traffic.
