  1. Which vessel has the right of way over all others under the Navigation Rules?

    Answer: A vessel not under command

    A vessel not under command (unable to maneuver) has the highest right-of-way priority because it cannot take action to avoid collision.

  2. What do five or more short blasts on a horn or whistle mean?

    Answer: Danger or doubt about the other vessel's intentions

    Five or more short blasts is the danger or doubt signal indicating the operator is uncertain of the other vessel's intentions.

  3. A motorboat is required to display which lights when operating between sunset and sunrise?

    Answer: Red port light, green starboard light, and white stern light

    Motorboats under 39.4 feet must display red (port), green (starboard), and white stern lights at night.

  4. When must a vessel give way to a vessel being overtaken?

    Answer: Always โ€” the vessel being overtaken is the stand-on vessel

    The vessel being overtaken always has the right of way; the overtaking vessel must keep clear until completely past and clear.

  5. What is a 'no-wake zone' and what speed is typically required?

    Answer: A zone where vessels must travel slowly enough to produce no wake, usually under 5 mph

    No-wake zones require vessels to travel at the minimum speed needed to maintain steerage, typically under 5 mph, to prevent wake damage.

  6. Which of these vessels must give way to a sailing vessel under sail alone?

    Answer: A powerboat under engine power

    A power-driven vessel must give way to a sailing vessel under sail alone, as sailboats are considered less maneuverable.

  7. Under U.S. law, how close to a U.S. Navy vessel may a recreational boat approach?

    Answer: 100 yards

    Federal law prohibits recreational vessels from coming within 100 yards of U.S. Navy ships to ensure security.
