- A.
Pilot Vessel
- B.
Sailing Vessel
- C.
Fishing Trawler
- D.
Power driven vessel underway
- E.
Vessel engaged in dredging
Correct Answer
D. Power driven vessel underwayExplanation
A power-driven vessel underway refers to a boat or ship that is being propelled by an engine or motor and is currently in motion. This means that the vessel is not at anchor, not aground, and not engaged in any specific activities such as fishing or dredging. It is simply in transit, using its engine or motor to move through the water.Rate this question:
-
- 2.
- A.
Hovercraft
- B.
Passenger Ferry
- C.
Power Vessel under 50m
- D.
Ship at Anchor
- E.
Power Vessel over 50M
Correct Answer
E. Power Vessel over 50MExplanation
The correct answer is "Power Vessel over 50M" because the question is asking for a category or type of vessel, and this option specifically refers to a powered vessel that is longer than 50 meters. The other options, such as "Hovercraft" and "Passenger Ferry," do not specify the size or length of the vessel, so they are not the correct answer. "Ship at Anchor" is also not the correct answer because it describes a specific situation or condition of a vessel, rather than a type or category.Rate this question:

A vessel displaying a flashing blue light is __________.
- A.
Transferring dangerous cargo
- B.
A law enforcement vessel
- C.
Engaged in a race
- D.
A work boat
Correct Answer
B. A law enforcement vesselExplanation
A vessel displaying a flashing blue light is likely a law enforcement vessel. Law enforcement vessels often use flashing blue lights to indicate their presence and authority while carrying out their duties, such as enforcing laws, conducting patrols, or responding to emergencies. The flashing blue light helps to alert other vessels and individuals to their presence and signifies that they are engaged in official law enforcement activities.Rate this question:

When power-driven vessels are crossing, a signal of one short blast by either vessel means __________.
- A.
"I intend to leave you on my port side"
- B.
"I intend to hold course and speed"
- C.
"I intend to leave you on my starboard side"
- D.
"I request a departure from the Rules"
Correct Answer
A. "I intend to leave you on my port side"Explanation
When power-driven vessels are crossing, a signal of one short blast by either vessel means "I intend to leave you on my port side." This means that the vessel making the signal intends to pass the other vessel on its left side. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which provide guidelines for safe navigation and prevent collisions between vessels.Rate this question:

Dredge engaged in dredging
- B.
Vessel engaged in fishing by trawling, trawl caught on obstruction
- C.
Dracone or partially submerged vessel or object being towed
- D.
Vessel aground, 50 meters or more in length
Correct Answer
C. Dracone or partially submerged vessel or object being towedExplanation
The correct answer is "Dracone or partially submerged vessel or object being towed." This means that the vessel or object in question is either a dracone (a type of boat used for towing) or a partially submerged vessel or object being towed by another vessel.Rate this question:
-
- 6.
- A.
Vessel engaged in fishing, gear extending more than 150 meters
- B.
Towing astern, tow length 200 meters or less
- C.
Towing astern, tow length more than 200 meters
- D.
Minesweeper, underway and making way
Correct Answer
B. Towing astern, tow length 200 meters or lessExplanation
This answer is correct because it states that the vessel is towing astern with a tow length of 200 meters or less. This means that the vessel is pulling something behind it with a rope or cable that is shorter than 200 meters. This is a specific condition that describes the activity of the vessel, which differentiates it from the other options provided.Rate this question:

C. All available means........Explanation
The correct answer is "all available means." This means that every vessel should use all the tools and resources at their disposal, such as radar, ARPA, ECDIS, and visual and auditory perception, to maintain a proper lookout. This ensures that they have a comprehensive understanding of the situation and can assess the risk of collision effectively.Rate this question:
-
- 10.
- A.
Vessel Restricted in Her Ability To Maneuver conducting underwater operations where an obstruction exists
- B.
Trawling Vessel Hauling Nets
- C.
Vessel engaged in pilotage duties
- D.
Vessel Constrained by her Draft
- E.
Vessel Aground
Correct Answer
D. Vessel Constrained by her DraftExplanation
A vessel constrained by her draft refers to a ship that is limited in its ability to maneuver due to its deep draft, which is the distance from the waterline to the bottom of the ship. This means that the ship is unable to change its course or speed easily, making it more vulnerable to collisions or other accidents. In this scenario, the vessel is likely operating in shallow waters where its draft restricts its movements, such as near a harbor entrance or a narrow channel.Rate this question:
-
- 11.
- A.
Vessel not under command
- B.
Power Vessel, > 50m in length
- C.
Vessel at anchor
- D.
Vessel aground
- E.
Vessels Restricted in Their Ability to Maneuver
Correct Answer
D. Vessel agroundExplanation
The correct answer is "Vessel aground." This means that the vessel is stuck or stranded on the ground or a submerged object, preventing it from moving or maneuvering. This can happen due to various reasons such as running aground on a sandbar, hitting a reef, or getting stuck in shallow waters. When a vessel is aground, it is unable to navigate or change its position until it is refloated or assisted by external means.Rate this question:
