Introduction
*This examination is designed to assess the knowledge and practical decision-making skills required for
bareboat chartering under ASA 104 standards. Candidates will demonstrate proficiency in vessel systems,
navigation, weather interpretation, anchoring, docking, and emergency response. The exam emphasizes real-
world application, ethical seamanship, and regulatory compliance. Questions include foundational theory,
professional scenarios, and critical thinking problems. Successful completion indicates readiness to act as a
bareboat skipper in coastal waters up to 20 nautical miles from shore, with responsibility for vessel, crew, and
legal obligations. No dated references are included; principles remain current for any charter season.*
,SECTION ONE: QUESTIONS 1–100
Question 1
What is the primary purpose of a sacrificial zinc anode on an inboard/outboard drive or sail drive?
A. To improve fuel efficiency
B. To prevent galvanic corrosion
C. To ground the electrical system
D. To increase shaft horsepower
🟢B
🔴 RATIONALE: Sacrificial zinc anodes corrode preferentially to protect underwater metal components from
galvanic corrosion caused by dissimilar metals in an electrolyte (seawater).
Question 2
While anchoring in a 10-knot breeze with a predicted increase to 25 knots, which scope ratio is most
appropriate for a all-chain rode?
A. 3:1
B. 5:1
C. 7:1
D. 10:1
🟢C
🔴 RATIONALE: For all-chain rode in moderate to strong winds, 7:1 provides adequate holding power and
allows for wind increase without dragging. 5:1 is marginal in 25 knots; 10:1 is excessive in this depth.
,Question 3
Under the Navigation Rules, a power-driven vessel underway at night shows which lights?
A. Red and green sidelights and a sternlight only
B. Red and green sidelights, a masthead light, and a sternlight
C. Only a white sternlight
D. A single all-around white light
🟢B
🔴 RATIONALE: Rule 23 requires power-driven vessels under 50 meters to display red/green sidelights, a
forward masthead light, and a sternlight. A second masthead light is optional for vessels under 50m.
Question 4
You are bareboat chartering and discover a small fuel leak from an injector line on the diesel engine. What is the
FIRST action?
A. Continue running to reach port
B. Tighten the fitting while engine runs
C. Shut down the engine and investigate
D. Apply tape to stop the leak
🟢C
🔴 RATIONALE: Diesel fuel leaks create fire risk and environmental hazard. Immediate shutdown prevents
atomized fuel spray near hot engine parts. Never tighten fuel fittings under pressure.
Question 5
What is the correct procedure for recovering a person who has fallen overboard in open water with wind and
, current?
A. Turn hard toward the person and stop downwind
B. Use a quick-stop method and approach with bow into wind and waves
C. Approach from upwind, keeping person on lee side
D. Reverse directly to the person
🟢C
🔴 RATIONALE: Approaching from upwind keeps the vessel from drifting onto the person. The lee side provides
shelter and easier recovery. The person should be to leeward to prevent hull contact.
Question 6
What does the term "bareboat charter" legally imply?
A. The charterer provides all provisions and crew
B. The charterer assumes full control, command, and responsibility for the vessel
C. The owner provides insurance and maintenance during charter
D. The vessel is uninsured and "bare" of all equipment
🟢B
🔴 RATIONALE: Bareboat charter transfers possession and control to the charterer, who becomes responsible
for navigation, safety, and legal compliance. The owner provides a seaworthy vessel but no operating crew.
Question 7
While sailing at night, you see a white light flashing every 6 seconds. What does this indicate?
A. A vessel aground
B. A pilot vessel on duty
