  1. Which factor most increases the risk of carbon monoxide poisoning on a boat?

    Answer: Running the generator while anchored in a confined area with poor ventilation

    Running engines or generators while anchored in a confined, poorly ventilated area traps CO exhaust and is a leading cause of on-board CO poisoning.

  2. A passenger is showing signs of hypothermia after being in cold water. What should you do?

    Answer: Remove wet clothing and warm the core gently

    Gentle core rewarming—removing wet clothes and applying warmth to the torso—is safest; rubbing limbs or alcohol can worsen the condition.

  3. What does a single prolonged blast on a horn (4–6 seconds) from a vessel in fog mean?

    Answer: A power-driven vessel is underway making way

    A single prolonged blast every two minutes signals a power-driven vessel making way in restricted visibility.

  4. When is it appropriate to abandon ship?

    Answer: When the vessel poses more danger than the water

    You should stay with the vessel as long as possible because a floating boat is easier to spot than a person in the water; abandon ship only when it becomes more dangerous than leaving.

  5. What information should be included in a Mayday call?

    Answer: Mayday spoken three times, vessel name, position, nature of distress, number of people aboard, and any other helpful information

    A proper Mayday call follows the standard format: MAYDAY MAYDAY MAYDAY, vessel name, position, nature of distress, souls aboard, and vessel description.

  6. A fire breaks out in the engine compartment. What is the safest first step?

    Answer: Shut off the fuel supply and discharge the extinguisher through the access port without fully opening the hatch

    Keeping the hatch mostly closed limits oxygen to the fire while allowing extinguisher agent to reach the flames; opening the hatch can cause a flashover.

  7. Which type of PFD is best suited for unconscious victims in rough, open water because it turns the wearer face-up?

    Answer: Type I (Offshore Life Jacket)

    Type I offshore life jackets are designed to turn an unconscious person face-up in rough open water, providing the highest level of protection.
