  1. A defensive boater planning a trip in unfamiliar waters should first:

    Answer: Study current nautical charts, check for hazards, and review local regulations

    Current nautical charts reveal underwater hazards, restricted areas, and channel markers that are essential for safe passage in unfamiliar waters.

  2. When is it appropriate to use a VHF radio Channel 16 in a defensive boating context?

    Answer: For distress calls, urgency messages, and hailing other vessels

    Channel 16 is the international distress and calling channel; all vessels must monitor it and use it for distress and initial contact.

  3. When operating a personal watercraft (PWC), defensive technique requires the operator to understand that:

    Answer: Letting off the throttle removes steering control on most PWCs

    Most PWCs use jet propulsion, so releasing the throttle removes steering control — operators must apply throttle to steer away from hazards.

  4. What does a vessel operator do to practice safe speed in accordance with COLREGS Rule 6?

    Answer: Adjust speed based on visibility, traffic, maneuverability, and background light

    Rule 6 requires operators to consider all relevant factors — not just a posted limit — when determining a safe speed for current conditions.

  5. A defensive boater notices a rapidly developing thunderstorm. The correct action is to:

    Answer: Head to the nearest safe harbor immediately, before lightning begins

    Thunderstorms develop quickly on water, and reaching shelter before lightning begins is the safest defensive action.

  6. Which factor does NOT contribute to bow-high operation ('porpoising') that a defensive boater should correct?

    Answer: Operating at planning speed in calm water

    Planing in calm water does not cause porpoising; improper weight distribution, trim tabs, and excessive engine trim-out are the common causes.

  7. Why should a defensive boater always carry and use a carbon monoxide (CO) detector aboard?

    Answer: CO is odorless and can incapacitate or kill passengers before they realize danger

    Carbon monoxide is colorless and odorless; it can build up in cockpit areas and enclosed spaces, causing incapacitation or death without warning.
