From the nature of her work is unable to keep out the way of another
- B.
They are fishing convoy
- C.
They are restricted to keep clear because of some exceptional circumstances
- D.
She is restricted to maneuver due to her fishing gear
Correct Answer
D. She is restricted to maneuver due to her fishing gearExplanation
A vessel engaged in fishing is restricted to maneuver due to her fishing gear. This means that the fishing gear, such as nets or lines, can limit the vessel's ability to change direction or avoid obstacles. The fishing gear may be spread out in the water, making it difficult for the vessel to navigate freely. Therefore, the vessel is unable to keep out of the way of another vessel or maintain a clear path.Rate this question:

When determining safe speed, factors such as the presence of background light, state of visibility, and maneuverability of the vessel are important to consider. However, the length and width of the vessel itself does not directly impact the safe speed. The size of the vessel may affect other aspects such as stability and handling, but it is not a determining factor in setting the safe speed.Rate this question:

Under Rule no. 2 paragraph b, which of the following reasons is considered best when departing from the rule
- A.
When there is immediate danger
- B.
Master's order
- C.
The failure of the OOW on compliance of the rules
- D.
Limitation of the vessel
Correct Answer
A. When there is immediate dangerExplanation
When there is immediate danger is considered the best reason for departing from the rule under Rule no. 2 paragraph b. This is because the safety of the vessel and its crew is of utmost importance, and if there is an immediate danger that could potentially harm the vessel or its occupants, it is necessary to deviate from the rule in order to avoid the danger and ensure the safety of everyone on board.Rate this question:

A vessel proceeding on a safe speed shall consider the following factor except
- A.
Night time
- B.
Draught of the vessel in relation to depth of the water
- C.
Traffic density
- D.
Restricted visibility
Correct Answer
A. Night timeExplanation
When a vessel is proceeding at a safe speed, it needs to consider various factors to ensure its safety. These factors include the draught of the vessel in relation to the depth of the water, traffic density, and restricted visibility. However, night time is not a factor that needs to be considered separately, as it falls under the category of restricted visibility. Therefore, the correct answer is night time.Rate this question:

How does an action by give way vessel be effective
- A.
When she alter course to port
- B.
When they are insight with one another
- C.
When done early and substantial
- D.
When a stand on vessel failed to act
Correct Answer
C. When done early and substantialExplanation
When an action by a give way vessel is done early and substantial, it means that the vessel takes prompt and significant measures to avoid a collision. By altering its course to port (left), the give way vessel effectively shows its intention to yield and allows the stand on vessel to maintain its course and speed. This early and substantial action helps in preventing a potential collision and ensures the safety of both vessels.Rate this question:

What light or lights can be seen from the overtaken vessel when you are within the 22.5 degrees abaft the beam
- A.
The masthead lights
- B.
The sidelights
- C.
Either the green or the red lights
- D.
The stern light
Correct Answer
C. Either the green or the red lightsExplanation
When a vessel is overtaking another vessel, it is required to exhibit either the green or the red lights. These lights are known as the sidelights and are visible from the overtaken vessel when the overtaking vessel is within the 22.5 degrees abaft the beam. The purpose of these lights is to indicate the direction in which the overtaking vessel is approaching from. Therefore, the correct answer is either the green or the red lights.Rate this question:

In an overtaking situation, what rule shall prevail when a vessel cross your bow from an overtaking situation
- A.
Overtaking situation
- B.
Overtaking followed by crossing rules
- C.
Crossing situation
- D.
Responsibilities between vessels
Correct Answer
A. Overtaking situationExplanation
In an overtaking situation, the rule that shall prevail is the overtaking followed by crossing rules. This means that the vessel that is overtaking another vessel has the responsibility to keep clear and avoid crossing the bow of the vessel being overtaken. The vessel being overtaken has the right of way and should maintain its course and speed. This rule helps to ensure safety and prevent collisions during overtaking maneuvers.Rate this question:

Which of the following vessel is allowed to use the traffic separation zone as specified under the rule
- A.
Sailing vessel
- B.
Vessel constrain by draft
- C.
Vessel less than 20 meters
- D.
Vessel en route while crossing
Correct Answer
D. Vessel en route while crossingExplanation
The vessel en route while crossing is allowed to use the traffic separation zone as specified under the rule. This means that if a vessel is actively crossing a waterway, it is permitted to use the designated traffic separation zone to navigate through the area. This is because the traffic separation zone is specifically designed to separate vessels traveling in different directions and to ensure safe and efficient navigation.Rate this question:
