ASA 103 TEST EXAM 200 ACTUAL QUESTIONS AND
CORRECT ANSWERS WITH RATIONALE LATEST
UPDATE ALREADY GRADED A+
The ASA 103 Basic Coastal Cruising test exam is a comprehensive written
assessment that evaluates a sailor's proficiency in intermediate coastal
navigation, safety protocols, and advanced boat handling. It covers chart
reading, tidal and current calculations, anchoring techniques, docking
maneuvers, sail trim, and collision regulations. The exam tests the ability to
apply navigational principles using compass bearings, depth soundings, and
dead reckoning. It also assesses emergency response skills, including man
overboard procedures, engine troubleshooting, and heavy weather tactics.
Success demonstrates readiness to skipper a sailing vessel in coastal waters
with confidence and competence.
Question 1
A sailboat is sailing on a starboard tack. Which vessel has the right of way when
encountering a power-driven vessel on a collision course?
A) The power-driven vessel
B) The sailboat
C) The vessel with the wind on its port side
D) The larger vessel
Answer: B
Rationale: Under the International Regulations for Preventing Collisions at Sea
(COLREGS), a sailboat under sail has the right of way over a power-driven vessel
unless the sailboat is overtaking or the power-driven vessel is restricted in its
ability to maneuver. A sailboat on starboard tack has the wind coming over its
starboard side.
Question 2
You are plotting a course on a nautical chart. What does a solid red circle with a
vertical stripe indicate?
A) A preferred-channel buoy
B) A safe water mark
C) A port-hand lateral buoy
,D) An isolated danger mark
Answer: A
Rationale: A solid red circle with a vertical stripe is a preferred-channel buoy,
indicating that the preferred channel is to the starboard side when entering from
seaward. A safe water mark has red and white vertical stripes. A port-hand buoy is
red. An isolated danger mark is black with red bands.
Question 3
What is the primary purpose of a lead line or depth sounder while coastal cruising?
A) To measure water temperature
B) To determine the depth of water under the keel
C) To measure wind speed
D) To determine the vessel's speed
Answer: B
Rationale: The primary purpose of a lead line or depth sounder is to measure water
depth to ensure sufficient clearance under the keel and to avoid grounding. It does
not measure temperature, wind speed, or vessel speed.
Question 4
A sailor observes a green light on the starboard side of another vessel at night.
What does this indicate?
A) The vessel is showing its port side
B) The vessel is showing its starboard side
C) The vessel is at anchor
D) The vessel is aground
Answer: B
Rationale: A green light is displayed on the starboard side of a vessel under way.
Seeing the green light indicates you are looking at the vessel's starboard side and
that vessel has the right of way if you are on a crossing course.
Question 5
When anchoring in a protected cove, what is the recommended scope for a nylon
anchor rode in calm conditions with a 10:1 ratio recommendation?
A) 3:1
B) 5:1
C) 7:1
D) 10:1
Answer: C
,Rationale: A 7:1 scope (length of rode to depth of water) is recommended for calm
conditions with a nylon rode to ensure adequate holding power. A 3:1 or 5:1 scope
may not provide sufficient holding. A 10:1 scope is used in storm conditions.
Question 6
What does the term "spring line" refer to in docking operations?
A) A line used to secure the bow to the dock
B) A line used to secure the stern to the dock
C) A line used to prevent forward and aft movement of the vessel while alongside
a dock
D) A line used to tow another vessel
Answer: C
Rationale: Spring lines are docking lines that lead forward or aft from the vessel to
the dock to prevent the vessel from moving forward or backward along the dock.
Bow and stern lines control movement away from the dock.
Question 7
The wind is blowing from the north. On which tack is a sailboat sailing if it is
heading due west?
A) Starboard tack
B) Port tack
C) Running tack
D) Close-hauled
Answer: B
Rationale: With wind from the north (windward side is north), a boat heading west
has the wind coming over its port side. Therefore, it is on port tack. Starboard tack
would have the wind over the starboard side.
Question 8
What is the correct procedure if a sailor falls overboard while the vessel is under
sail?
A) Immediately throw a life ring and perform a quick-stop maneuver to return to
the person
B) Continue sailing and call for help on the VHF radio
C) Turn the vessel downwind and return in a large circle
D) Drop the anchor immediately
Answer: A
Rationale: The immediate response to a man overboard is to throw a flotation
device (life ring) and perform a quick-stop or figure-eight maneuver to return to
, the person as quickly as possible. Continuing to sail or dropping anchor wastes
time and may lose sight of the person.
Question 9
What does a "tidal range" represent?
A) The maximum speed of the tidal current
B) The vertical difference between high tide and low tide
C) The horizontal distance the tide travels
D) The time between two successive high tides
Answer: B
Rationale: Tidal range is the vertical difference between the height of high water
and the height of low water at a given location. It is not related to current speed,
horizontal distance, or time between tides.
Question 10
What is the purpose of a "spinnaker" sail?
A) To increase stability in heavy winds
B) To provide propulsion when sailing downwind
C) To reduce heeling in strong winds
D) To serve as a storm sail
Answer: B
Rationale: A spinnaker is a large, lightweight sail designed for downwind sailing to
maximize propulsion in light to moderate winds. It is not used for stability,
reducing heel, or storm conditions.
Question 11
On a nautical chart, what does a dashed line with small dots indicate?
A) A ferry route
B) A cable or pipeline
C) A recommended track or fairway
D) A boundary line
Answer: C
Rationale: A dashed line with small dots on a nautical chart indicates a
recommended track or fairway for navigation. Ferry routes, cables, and boundaries
have different symbols.
Question 12
What is the immediate action when the vessel's engine overheats?
A) Increase engine speed to cool it down
B) Shut off the engine and investigate the cause
