10. Crew Management and Leadership
Introduction
*This comprehensive examination assesses the advanced knowledge and practical decision-making skills
required for ASA 106 certification. Candidates must demonstrate mastery of coastal navigation, weather
interpretation, vessel systems, emergency response, and regulatory compliance. The assessment comprises 200
multiple-choice questions, including scenario-based problems that mirror real-world challenges encountered on
extended coastal passages. Each question emphasizes applied reasoning rather than rote memorization.
Successful candidates will be prepared to act as confident, responsible skippers capable of managing a cruising
sailboat in moderate to challenging conditions, integrating technical proficiency with sound judgment and
ethical seamanship.*
,SECTION ONE: QUESTIONS 1–100
Question 1
You are planning a 60-nautical-mile coastal passage. The tidal stream atlas shows a maximum spring rate of 2.5
knots at the midpoint. Your boat’s speed is 6 knots. What is the most significant factor in calculating estimated
time of arrival?
A. Leeway caused by wind direction
B. Distance measured on the chart
C. Cross-track error from GPS waypoints
D. The cumulative effect of tidal stream vectors
🟢D
🔴 RATIONALE: Tidal streams can add or subtract from speed over ground. With a 2.5-knot stream, your net
speed could range from 3.5 to 8.5 knots, making cumulative vector effect the dominant ETA factor.
Question 2
A squall line is approaching from the southwest with winds forecast to gust to 45 knots. Your vessel is on a
starboard tack with full main and genoa. What is the safest immediate action?
A. Continue on course but release the mainsheet completely
B. Round up into the wind and heave-to
C. Reef the main and furl the genoa before the squall hits
D. Bear away to a broad reach and sail at high speed ahead of the squall
🟢C
🔴 RATIONALE: Reducing sail area before the squall strikes prevents loss of control and reduces heeling force.
,Reefing the main and furling the genoa is the standard precautionary action for an approaching squall.
Question 3
According to the Navigation Rules (COLREGS), which vessel is stand-on when two power-driven vessels are
crossing with risk of collision?
A. The vessel that sounds one short blast
B. The vessel that has the other on its starboard side
C. The vessel that is to port of the other vessel
D. The vessel that is to starboard of the other vessel
🟢D
🔴 RATIONALE: Rule 15 requires that when two power-driven vessels are crossing, the vessel which has the
other on its own starboard side shall keep out of the way. The vessel on the starboard side is the stand-on
vessel.
Question 4
You observe a gradual decrease in engine RPM despite full throttle, accompanied by black smoke from the
exhaust. The most likely cause is:
A. Clogged fuel filter
B. Air in the hydraulic steering system
C. Overcharged battery
D. Worn alternator belt
🟢A
🔴 RATIONALE: Black smoke indicates incomplete combustion due to fuel starvation. A clogged fuel filter
, restricts fuel flow, causing RPM drop and black smoke under load.
Question 5
Your vessel is at anchor in a crowded harbor at night. What is the legally required anchor light configuration for
a vessel under 50 meters?
A. All-round white light visible for 2 miles
B. Two all-round white lights (forward and aft)
C. One white light at the masthead and one at the stern
D. Tricolor light at the top of the mast
🟢A
🔴 RATIONALE: COLREGS Rule 30(a) requires a vessel at anchor under 50 meters to display an all-round white
light where it can best be seen, visible for 2 miles.
Question 6
While sailing in fog with limited visibility, you hear one prolonged blast followed by two short blasts from
another vessel. This signal indicates:
A. A power-driven vessel making way
B. A vessel restricted in her ability to maneuver
C. A vessel under sail
D. A vessel aground
🟢C
🔴 RATIONALE: Rule 35(c) states that a sailing vessel under way in restricted visibility shall sound one
prolonged blast followed by two short blasts at intervals of not more than two minutes.
