1.
When approaching a berth with a strong crosswind, the best initial maneuver is
to:
A. Approach at a steep angle to the berth
B. Approach parallel to the berth
C. Approach at a shallow angle into the wind
D. Approach stern-first
Rationale: Approaching slightly into the wind gives better control and reduces drift
toward or away from the berth.
2.
A vessel’s pivot point while making headway is located:
A. At the stern
B. At midships
C. Forward of midships
D. At the bow
Rationale: With headway, the pivot point shifts forward, typically about 1/3 the
ship’s length from the bow.
3.
What is the most effective use of tugs when docking a large tanker in confined
waters?
A. Stern tug only
B. Tugs fore and aft, coordinated by the pilot
,C. Only bow tug
D. None, use ship’s engines alone
Rationale: Using tugs fore and aft provides control of both ends and is standard
for safe maneuvering.
4.
Which current condition poses the greatest challenge when docking?
A. Following current
B. Strong cross-current
C. Ebb current with the vessel’s bow upstream
D. Slack water
Rationale: A cross-current can push the vessel sideways, reducing control.
5.
The “squat effect” is greatest when:
A. A vessel is light-loaded in shallow water
B. A vessel is heavily loaded in shallow water at high speed
C. A vessel is stopped in deep water
D. A vessel is drifting with current
Rationale: Squat increases with speed and shallow draft-to-depth ratios, most
pronounced in shallow water.
6.
While handling a ship with a right-handed fixed-pitch propeller, backing full astern
will cause the stern to:
A. Move to port
B. Move to starboard
C. Move ahead
D. Remain stationary
, Rationale: Propeller transverse thrust (prop walk) pulls the stern to starboard with
a right-handed propeller.
7.
Which tool is essential for real-time navigation in restricted visibility within a
harbor?
A. Sextant
B. Chronometer
C. Radar with ARPA
D. Sounding machine
Rationale: Radar/ARPA provides situational awareness, especially in poor visibility.
8.
In a narrow channel, the vessel that must keep to the starboard side is:
A. Vessels under sail
B. Fishing vessels
C. All power-driven vessels
D. Only vessels over 100 meters
Rationale: COLREG Rule 9 requires power-driven vessels in narrow channels to
keep to starboard.
9.
When a vessel is moored with a spring line, its primary effect is to:
A. Prevent the ship from heeling
B. Prevent fore and aft movement
C. Prevent sideways drift
D. Reduce yawing at anchor
Rationale: Spring lines restrain fore-and-aft movement along the pier.
