Introduction
This comprehensive examination is designed to assess the essential knowledge and practical skills
required for successful coastal cruising under sail. The exam evaluates a candidate's proficiency in
navigation, boat handling, safety protocols, and regulatory compliance through a combination of
theoretical questions and applied scenarios. Candidates will demonstrate their ability to interpret
nautical charts, execute docking and anchoring maneuvers, respond to emergencies, and make sound
decisions in varied weather conditions. The multiple-choice format emphasizes real-world application,
requiring critical thinking and the integration of technical knowledge with seamanship judgment. This
assessment serves as a rigorous evaluation of a mariner's readiness for independent coastal sailing.
SECTION ONE: QUESTIONS 1–100
Question 1
What is the primary purpose of the red and green navigation lights on a sailboat under sail at
night?
A. To indicate the boat's length and tonnage
B. To show the vessel's direction of travel and which side is which
C. To signal distress to other vessels
D. To illuminate the deck for crew safety
🟢 B. To show the vessel's direction of travel and which side is which
🔴 Explanation: Red (port) and green (starboard) navigation lights indicate the vessel's orientation
and direction of travel to other mariners. This allows vessels to determine who has right-of-way and
,avoid collisions. They do not indicate length, distress, or provide deck illumination.
Question 2
When entering a narrow channel, a sailboat under power must:
A. Maintain course and speed regardless of other traffic
B. Yield to all vessels displaying a blue light
C. Keep to the starboard side of the channel
D. Sound one prolonged blast every two minutes
🟢 C. Keep to the starboard side of the channel
🔴 Explanation: Rule 9 of the Navigation Rules requires vessels in narrow channels to keep as far to
the starboard side of the channel as is safe and practicable. This promotes orderly traffic flow and
reduces collision risk.
Question 3
What action should you take if you observe a red buoy with the number "4" on it while returning
from sea?
A. Keep it on your starboard side
B. Keep it on your port side
C. Pass directly over it
D. Anchor immediately
🟢 B. Keep it on your port side
🔴 Explanation: Red buoys are marked with even numbers and should be kept on your starboard
side when returning from sea (red right returning). Since you are returning from sea, this red buoy
should be kept on your port side.
Question 4
What does the term "luffing" refer to in sailing?
A. The boat leaning excessively to one side
B. The sail flapping due to improper trim or pointing too high into the wind
C. The anchor dragging along the bottom
D. The engine overheating during operation
🟢 B. The sail flapping due to improper trim or pointing too high into the wind
🔴 Explanation: Luffing occurs when the leading edge of the sail begins to flap or flutter because
the boat is pointed too close to the wind or the sail is not properly trimmed. It indicates a loss of
,power and requires trimming or bearing away.
Question 5
Which of the following is a legal requirement for carrying a VHF marine radio on a recreational
vessel?
A. It must be registered with the FCC and have a valid station license
B. It must be used only for emergency communications
C. The operator must hold a Restricted Radiotelephone Operator Permit
D. It must be capable of transmitting on both VHF and SSB frequencies
🟢 A. It must be registered with the FCC and have a valid station license
🔴 Explanation: VHF marine radios used on vessels must be licensed by the FCC, and the station
license must be carried onboard. While some exceptions exist for certain vessels, a license is
generally required for transmitting.
Question 6
What is the proper procedure for "heaving to" in rough weather?
A. Drop anchor and wait for conditions to improve
B. Back the jib, sheet the main amidships, and lash the helm to leeward
C. Lower all sails and deploy a sea anchor
D. Turn the boat into the wind and motor at idle speed
🟢 B. Back the jib, sheet the main amidships, and lash the helm to leeward
🔴 Explanation: Heaving to is a storm tactic where the boat is positioned to maintain a steady, slow
drift with minimal forward motion. This is achieved by backing the jib, sheeting the mainsail
amidships, and securing the helm to leeward, creating a balanced state.
Question 7
A vessel with a green sidelight visible to you is:
A. Overtaking you from the port side
B. Crossing your path from starboard to port
C. A vessel at anchor
D. A vessel in distress
🟢 B. Crossing your path from starboard to port
🔴 Explanation: A green sidelight indicates the starboard side of a vessel. If you see a green light,
the other vessel is crossing from your port to starboard, and you may be the give-way vessel
, depending on the situation.
Question 8
How often should the U.S. Coast Guard require that fire extinguishers be inspected or serviced?
A. Monthly
B. Annually
C. Every five years
D. Only when visibly damaged
🟢 B. Annually
🔴 Explanation: Fire extinguishers should be inspected annually to ensure they are in proper
working condition. Coast Guard regulations recommend checking for pressure, visible damage, and
expiration.
Question 9
When sailing on a starboard tack, you have right-of-way over:
A. A vessel on port tack
B. A vessel on starboard tack
C. A power-driven vessel
D. A vessel at anchor
🟢 A. A vessel on port tack
🔴 Explanation: Under sail, the starboard tack vessel has right-of-way over a port tack vessel. This
is a fundamental rule of the road that prevents confusion when sailboats converge.
Question 10
What is the significance of a blue "H" symbol on a nautical chart?
A. Hospital or heliport location
B. Harbor entry point
C. Hazardous area
D. Historical landmark
🟢 A. Hospital or heliport location
🔴 Explanation: A blue "H" symbol on nautical charts indicates a hospital or heliport, useful for
emergency planning and medical evacuations.
