1. What is the primary purpose of the International Regulations for
Preventing Collisions at Sea (COLREGS)?
A. To regulate cargo operations
B. To prevent collisions between vessels
C. To set ship construction standards
D. To govern port tariffs
Answer: B
Rationale: The COLREGS establish navigation rules to prevent
collisions at sea by standardizing vessel behavior in different
situations.
2. Which light configuration indicates a power-driven vessel
underway at night?
A. Red over green
B. Two red lights
C. Masthead light, sidelights, and stern light
D. Two white masthead lights only
Answer: C
Rationale: A power-driven vessel underway displays masthead
light(s), sidelights, and a stern light to indicate its status and
direction.
,3. What is the minimum number of whistle blasts indicating a vessel
is altering course to port?
A. One short blast
B. Two short blasts
C. Three short blasts
D. Five short blasts
Answer: B
Rationale: Two short blasts indicate an intention to alter course
to port under COLREGS.
4. What is dead reckoning in navigation?
A. Position using satellite GPS
B. Position determined by celestial observations only
C. Estimating position based on course and speed from last known
position
D. Position using radar fixes only
Answer: C
Rationale: Dead reckoning estimates current position based on
speed, time, and course from a known position.
5. What is the primary function of a gyrocompass?
A. Measure wind direction
B. Indicate true north
C. Measure water depth
D. Detect ship speed
Answer: B
Rationale: A gyrocompass finds true north using Earth's rotation,
unlike a magnetic compass.
6. What does the term “free surface effect” refer to?
A. Ice forming on deck
B. Movement of liquid in partially filled tanks affecting stability
, C. Wind pressure on the hull
D. Cargo shifting in containers
Answer: B
Rationale: Free surface effect reduces stability due to shifting
liquids in partially filled tanks.
7. What is the primary purpose of a ship’s bilge system?
A. Fire suppression
B. Removing water from lower compartments
C. Fuel transfer
D. Steering control
Answer: B
Rationale: The bilge system removes unwanted water from the
lowest parts of the vessel.
8. What does a red buoy typically indicate in IALA Region B?
A. Safe water
B. Mid-channel
C. Starboard side of channel
D. Port side of channel
Answer: C
Rationale: In Region B (Americas), red buoys mark the starboard
side when returning from sea.
9. What is the purpose of an anchor?
A. Increase vessel speed
B. Steer the vessel
C. Secure vessel in position
D. Measure depth
Answer: C
Rationale: Anchors hold a vessel in place by gripping the seabed.
