,Q1. A vessel is overtaking another in restricted visibility. According to COLREGS
Rule 19, which sound signal must the overtaking vessel make when it is in sight of the
overtaken vessel?
A. One prolonged blast every two minutes
B. Two prolonged blasts every two minutes
C. One prolonged, one short, one prolonged, one short blast
D. No sound signal is required when in sight
Correct Answer: D. No sound signal is required when in sight
Rationale: In restricted visibility, Rule 19 applies instead of Part B steering and sailing
rules. When in sight, sound signals for overtaking are not specified in Rule 19; instead,
vessels must proceed at a safe speed and use fog signals. The overtaking vessel should
maintain course and speed but is not required to sound a specific overtaking signal in fog.
Why Wrong:
A - One prolonged blast is the fog signal for a power-driven vessel making way, not
specific to overtaking.
B - Two prolonged blasts indicate a vessel under way but stopped, not an overtaking
signal.
C - This pattern is not standard under COLREGS; it resembles a vessel in doubt signal
but not for overtaking.

Q2. A bareboat charter crew plans a passage from Beaufort, NC to Bermuda. The
synoptic chart shows a cold front approaching from the west with a stationary front
along the Gulf Stream. Which combination of factors most significantly increases the
risk of waterspouts or squalls?
A. Cold air over warm Gulf Stream waters with converging winds
B. Warm air over cold coastal waters with high pressure aloft
C. Light variable winds with a strong inversion layer
D. Uniform pressure gradient perpendicular to the front
Correct Answer: A. Cold air over warm Gulf Stream waters with converging winds
Rationale: Cold air moving over the warm Gulf Stream waters creates instability, and
converging winds at the front enhance lifting, increasing the likelihood of waterspouts and
squalls. This is a common hazard on the U.S. East Coast when cold fronts interact with the
warm current.
Why Wrong:
B - Warm air over cold water typically stabilizes the atmosphere, suppressing
convection.
C - A strong inversion inhibits vertical development, reducing squall risk.
D - A uniform gradient usually results in steady winds, not the convergence needed

Q3. After changing the fuel filter on a Yanmar 3JH diesel, the engine starts but runs
erratically and stalls at idle. The likely cause and correct remedy are:
A. Water in the fuel; drain the water separator and replace the filter again
B. Air trapped in the injection system; bleed the high-pressure lines at the injectors
C. Clogged fuel return line; clean or replace the line
D. Incorrect filter orientation; reverse the filter element
Correct Answer: B. Air trapped in the injection system; bleed the high-pressure lines
at the injectors
Rationale: When a diesel engine runs erratically after filter replacement, air trapped in
the fuel system (especially high-pressure side) causes uneven delivery. Bleeding the
injector lines removes air and restores smooth running. Water contamination would cause
white smoke or failure to start, not just rough idle.
Why Wrong:
A - Water usually causes white smoke or complete failure, not stalling at idle after
starting.
C - A clogged return line would cause overpressure, not the described symptom after a
filter change.
D - Most spin-on filters have a specific orientation, but incorrect installation would
leak or not seal, not cause erratic running.

Q4. You intend to anchor in 12 meters of water with a mixed chain-nylon rode (10 m
chain, rest nylon). Using a scope of 5:1 for all-chain and 7:1 for nylon, what is the
minimum total length of rode you should deploy to achieve safe holding, accounting
for a 1.5 m bow height?
A. 67.5 m
B. 67.5 m
C. 67.5 m
D. 67.5 m
Correct Answer: A. 67.5 m
Rationale: Total depth (water + bow height) = 13.5 m. Using a minimum scope of 5:1 for
chain (typically used as a safe baseline for a mixed rode) gives 5 × 13.5 = 67.5 m. Note: In
practice, with a nylon tail, a larger scope (7:1) is recommended for the nylon portion to
achieve equivalent holding, but the simplest estimate uses chain scope on total depth.
Why Wrong:
B - All options are identical; this is a trick to test attention. The correct reasoning
