,Q1. A bareboat charter skipper is planning a passage from San Diego to Ensenada, Mexico. The vessel is
equipped with a GPS chartplotter, but the skipper notices the displayed position differs from a radar fix by
0.5 nautical miles. Which of the following is the most likely cause of this discrepancy?
A. GPS selective availability is still active, causing intentional degradation.
B. The chartplotter's datum is set to WGS84, while the radar overlay uses NAD27.
C. Radar bearings are subject to greater error than GPS at short ranges.
D. The GPS antenna is mounted too close to the mast, causing multipath error.
Correct Answer: B. The chartplotter's datum is set to WGS84, while the radar overlay uses NAD27.
Rationale: The most likely cause is a datum mismatch between GPS (WGS84) and radar (often NAD27 on older
charts). Selective availability was turned off in 2000, so A is incorrect. Radar bearings can be accurate, but datum
differences cause systematic offsets, not random error. Multipath error is usually smaller and intermittent.
Why Wrong:
A - Selective availability was discontinued in 2000, so it is not a current cause.
C - Radar bearings can be very accurate at short ranges; the discrepancy is systematic, not random.
D - Multipath error typically causes intermittent errors, not a consistent 0.5 NM offset.

Q2. During a bareboat charter, the engine fails to start. The batteries are fully charged, and the starter motor
engages but cranks slowly. Which diagnostic step should be performed first?
A. Check the fuel shut-off valve and bleed the fuel system.
B. Inspect the battery cables for corrosion and tightness.
C. Test the glow plugs for continuity.
D. Replace the starter solenoid.
Correct Answer: B. Inspect the battery cables for corrosion and tightness.
Rationale: Slow cranking with fully charged batteries often indicates high resistance in the starting circuit, most
commonly due to corroded or loose battery cables. Checking cables is quick and non-invasive. Fuel issues would
not affect cranking speed. Glow plugs are for cold starts, not cranking speed. Replacing the solenoid is premature
without testing connections.
Why Wrong:
A - Fuel system issues would not cause slow cranking; the starter speed is unaffected by fuel.
C - Glow plugs are used for preheating in diesel engines, not for cranking speed.
D - A faulty solenoid usually results in no cranking, not slow cranking.

Q3. A 40-foot sailboat is approaching a narrow channel with a following sea. The skipper intends to enter the
channel and dock starboard side to a pier. Which of the following is the most appropriate approach?
A. Approach the channel entrance at a 45-degree angle to the waves, then turn parallel to the channel once
inside.
B. Maintain a course directly into the waves until just before the entrance, then execute a sharp turn to align
with the channel.
C. Reduce speed and approach the channel at a slight angle to the waves, using engine power to maintain
steerage.
D. Approach the channel at a 90-degree angle to the waves to minimize rolling.
Correct Answer: C. Reduce speed and approach the channel at a slight angle to the waves, using engine
power to maintain steerage.
Rationale: A following sea can cause broaching or loss of steerage. Reducing speed and approaching at a slight
angle (e.g., 10-20 degrees) allows the skipper to maintain control and avoid being pushed sideways. A 45-degree
angle risks beam seas and instability. A sharp turn just before the entrance is dangerous due to wave action. A
90-degree approach would expose the beam to following seas, increasing roll and risk of broaching.
Page 3
, Why Wrong:
A - A 45-degree angle exposes the beam to following seas, increasing roll and potential broaching.
B - A sharp turn in a following sea can cause broaching or loss of control.
D - A 90-degree angle would place the vessel beam-to the waves, causing heavy rolling and potential capsize.
Reference: ASA 104 Bareboat Cruising Manual, Section 5.3
Q4. A charter skipper is evaluating the stability of a 35-foot sloop after loading stores. The vessel's righting
arm (GZ) curve shows a maximum GZ of 2.5 feet at 30 degrees of heel. Which of the following conclusions is
correct?
A. The vessel has adequate stability for coastal cruising, as the maximum GZ exceeds 2 feet.
B. The vessel may be tender, as the angle of maximum GZ is relatively low.
C. The vessel is likely overloaded, causing a reduced range of positive stability.
D. The vessel's stability is insufficient because the maximum GZ occurs at less than 40 degrees.
Correct Answer: B. The vessel may be tender, as the angle of maximum GZ is relatively low.
Rationale: A maximum GZ at 30 degrees indicates a relatively tender vessel (typical for cruising sailboats is 40-50
degrees). While the GZ value of 2.5 ft is adequate, the low angle suggests the vessel will heel easily. The maximum
GZ value alone does not indicate overloading; the range of positive stability (typically >120 degrees) is needed. A
maximum GZ below 40 degrees is common for some designs and not inherently insufficient.
Why Wrong:
A - Maximum GZ value alone is not sufficient; the angle at which it occurs is critical for assessing tenderness.
C - Overloading would reduce the range of positive stability and maximum GZ angle, but the given data does
not indicate overloading.
D - Many seaworthy cruising sailboats have maximum GZ between 30-40 degrees; it is not automatically
insufficient.

Q5. While at anchor in a crowded harbor, a bareboat skipper notices the vessel is swinging in a different arc
than nearby boats. The skipper suspects the anchor is not holding. Which of the following actions should be
taken first?
A. Immediately start the engine and motor forward to take strain off the anchor rode.
B. Pay out more scope and monitor the position relative to fixed objects.
C. Weigh anchor and reset it in a different location.
D. Set a second anchor to prevent dragging.
Correct Answer: B. Pay out more scope and monitor the position relative to fixed objects.
Rationale: The first action should be to increase scope if possible, as insufficient scope is a common cause of
dragging. Monitoring position relative to fixed objects confirms dragging. Starting the engine is prudent but
motoring forward without assessing the situation can be dangerous. Weighing anchor immediately may be
premature if more scope resolves the issue. Setting a second anchor is a secondary action after assessing scope.
Why Wrong:
A - Motoring forward without first assessing scope may cause the anchor to break out or cause collision.
C - Weighing anchor is a last resort; increasing scope is simpler and faster.
D - Setting a second anchor is appropriate if dragging continues after increasing scope.
Reference: ASA 104 Bareboat Cruising Manual, Section 6.2
Q6. A charter crew consists of four adults with varying experience. The skipper is responsible for crew
safety. Which of the following tasks should be assigned to the most experienced crew member (other than the
skipper)?
A. Helming the vessel during the departure from the dock.
B. Monitoring the VHF radio for weather updates.
