Container ships are specifically built to transport cargo in standardized containers. They use cell guides in the holds and on deck to secure containers. This design optimizes loading, unloading, and global intermodal transport.
The right side of a vessel when facing the bow is known as which of the following?
Starboard
Aft
Beam
Port
Starboard refers to the right-hand side of a vessel when facing forward toward the bow. Port is the opposite side. The terminology helps avoid confusion in navigation and operations.
Which vessel is not self-propelled and is often towed or pushed by another craft?
Yacht
Patrol boat
Tugboat
Barge
A barge is a flat-bottomed vessel that has no means of self-propulsion and must be towed or pushed by tugboats. Barges are commonly used on rivers and canals for cargo transport. This distinguishes them from motorized vessels.
Which of the following items is used for personal flotation in case of abandonment?
Foghorn
Anchor
Radar
Life jacket
Life jackets provide buoyancy to keep a person afloat in the water and are a critical piece of safety equipment. They are mandatory on most vessels for each person aboard. Radar, anchors, and foghorns serve different functions.
Which navigational term refers to the front end of a vessel?
Bow
Stern
Keel
Beam
The bow is the forward-most part of a vessel that first contacts the water. The stern is the rear, and the beam is the widest part of the hull. The keel runs along the bottom of the hull.
What type of maintenance involves removing marine fouling and growth from the underwater hull?
Sounding
Scantling
Ballasting
Hull cleaning
Hull cleaning removes barnacles, algae, and other fouling organisms from the submerged hull surfaces. This process improves fuel efficiency and vessel speed. Ballasting, sounding, and scantling refer to different procedures.
The deadweight tonnage (DWT) of a vessel refers to which of the following?
Weight of the empty ship
Maximum weight of cargo, fuel, stores, and passengers
Volume of the cargo holds
Total displacement of the vessel
Deadweight tonnage represents the maximum weight a vessel can safely carry, including cargo, fuel, freshwater, provisions, passengers, and crew. It does not include the weight of the ship itself. It is a key measure of vessel capacity.
Which signal flag indicates that a vessel has a diver down and other vessels should keep clear at slow speed?
Quebec
Bravo
Delta
Alpha
The International Code of Signals flag Alpha (white and blue) indicates that divers are in the water and that passing vessels should keep clear at slow speed. This flag ensures diver safety. Bravo is used for dangerous goods.
In vessel stability, the term 'list' refers to which condition?
Vertical movement of the vessel
Temporary heel under wind pressure
Longitudinal bending of the hull
Permanent lateral tilt due to uneven loading
List is a static, permanent tilt to one side caused by uneven weight distribution on board. Heel is a temporary tilt caused by wind, waves, or maneuvering. List affects stability calculations and safe loading.
Freeboard on a vessel is defined as which of the following?
Interior deck height
Vertical distance from waterline to main deck
Distance between port and starboard sides
Horizontal distance from bow to stern
Freeboard is the vertical distance from the waterline up to the main deck level. It provides a measure of reserve buoyancy and safety margin against waves or overloading. It does not refer to horizontal dimensions.
According to COLREGs, what sound signal must a power-driven vessel make when underway but not making way in restricted visibility?
Three successive blasts
Two short blasts
One prolonged blast of 4-6 seconds
Rapid ringing of a bell
Rule 35 of the International Regulations for Preventing Collisions at Sea requires one prolonged blast at intervals not exceeding two minutes for a power-driven vessel making no way in restricted visibility. This distinguishes it from other signal patterns.
What is the primary purpose of the keel in a vessel's hull design?
Mounting point for navigation lights
Structural backbone providing strength
Housing for engine components
Storage for ballast
The keel is the central structural member running along the bottom of the hull, acting as the backbone and providing longitudinal strength. It also helps align the hull during construction. It is not used for storage or engine housing.
On nautical charts, what does the term chart datum refer to?
Reference plane for all height measurements
Baseline for compass variation
Mean sea level for tidal calculations
Reference plane for depth measurements
Chart datum is the reference level (usually the lowest astronomical tide) from which water depths are measured and charted. Mariners use it to ensure safe under-keel clearance. It is not related to elevation above water.
Which inspection procedure uses ultrasonic waves to measure hull plate thickness without removal of paint or coatings?
Draft survey
Ultrasonic thickness gauging
Radiographic testing
Magnetic particle inspection
Ultrasonic thickness gauging uses sound waves to measure the thickness of hull plates through coatings. It is a non-destructive testing method widely used in ship surveys. Draft surveys measure displacement, not plate thickness.
VHF marine radio channel 16 is designated internationally for which purpose?
Distress, safety, and calling
Routine commercial traffic
Weather broadcasts only
Harbor operations
VHF channel 16 (156.8 MHz) is reserved globally for distress, safety, and initial calling communications. All ships are required to monitor this channel. Other activities must switch to a working channel after contact.
In stability calculations, GM (metacentric height) equals KM minus KG. What does KM represent?
Distance from keel to center of gravity
Distance from keel to metacentre
Distance from keel to buoyancy center
Distance from keel to waterline
KM is the distance from the keel to the metacentre, a key geometric property in stability calculations. KG is measured from keel to center of gravity. The difference GM indicates initial stability.
If a vessel's sinkage coefficient is 1 cm per 10 tons and 500 tons of cargo are loaded, by how much will the draft increase?
50 cm
5 m
500 cm
5 cm
A sinkage coefficient of 1 cm per 10 tons means each 10 tons increases draft by 1 cm. Loading 500 tons produces 500 รท 10 = 50 cm of additional draft. This linear relationship is used in loading calculations.
When the 'Q' (Quebec) flag is hoisted alone onboard a vessel, it signifies which of the following?
Vessel is healthy and requests free pratique
Stationary with restricted maneuverability
Engines are operating astern
Vessel is carrying dangerous cargo
Under the International Code of Signals, the 'Q' flag indicates that the vessel is declaring itself free of disease and requests pratique (clearance to enter port). It does not relate to dangerous cargo or engine status.
What information do Cross Curves of Stability provide to a naval architect?
Righting arm values at different angles of heel
Hull resistance at various speeds
Optimal engine loading parameters
Longitudinal strength distribution
Cross Curves of Stability plot righting arm (GZ) against angle of heel for different displacements. They are essential for assessing vessel behavior under heeling forces. They do not relate to resistance or engine loads.
On a ship's Plimsoll (load line) mark, which indicator denotes tropical freshwater service?
TF
S
F
T
The 'TF' mark on the Plimsoll line indicates the maximum safe loading condition for tropical freshwater. Other letters denote conditions such as fresh water only (F), summer (S), or tropical sea (T).
