Which of the following conditions does not define a vessel constrain by draft
- A.
  
  The draft is a little less than the depth of the water
- B.
  
  When she experienced squat
- C.
  
  When she is in deep water
- D.
  
  The bottom is near the sea bottom
Correct Answer
C. When she is in deep water

Explanation
This condition does not define a vessel constrained by draft because being in deep water does not impose any restrictions or limitations on the vessel's draft. The draft of a vessel refers to the vertical distance between the waterline and the deepest part of the vessel below the water's surface. In deep water, the vessel has sufficient depth to navigate without any concerns about draft limitations. Therefore, this condition is not relevant to defining a vessel constrained by draft.

- A.
  
  Maintain your course and speed
- B.
  
  Avoid altering course to port towards the other vessel
- C.
  
  Increase your speed
- D.
  
  Sound an appropriate signal for a crossing situation
Correct Answer
A. Maintain your course and speed

Explanation
As a stand on vessel, your possible action would be to maintain your course and speed. This is because the vessel who is required to keep out of the way of another is already taking appropriate action in the crossing situation. By maintaining your course and speed, you are allowing the give-way vessel to navigate around you safely. Altering course to port towards the other vessel or increasing your speed could potentially create confusion and increase the risk of a collision. Sounding an appropriate signal for a crossing situation is not necessary in this scenario as the other vessel is already taking appropriate action.

  Cross at right angle of the channel
- C.
  
  Keep clear of the vessel navigating safely a narrow channel
- D.
  
  Cross with caution and observe the direction of the traffic
Correct Answer
C. Keep clear of the vessel navigating safely a narrow channel

Explanation
When crossing a narrow channel, it is important to keep clear of the vessel that is navigating safely through the channel. This means giving the right of way to the vessel that is already in the channel and ensuring that there is enough distance between your vessel and the navigating vessel to avoid any potential collisions or interference with its path. By keeping clear, you are prioritizing the safety and navigation of the vessel that is already in the narrow channel.

Which of the following vessels is exempted from the rules of the traffic separation scheme
- A.
  
  Vessel maintaining aids to navigation
- B.
  
  R.A.M.
- C.
  
  Submarine cable layer in operation
- D.
  
  All of the above
Correct Answer
C. Submarine cable layer in operation

Explanation
A submarine cable layer in operation is exempted from the rules of the traffic separation scheme. This is because a submarine cable layer is responsible for laying and maintaining submarine cables, which are essential for telecommunications and other purposes. Due to the nature of their work, submarine cable layers may need to deviate from the normal traffic separation scheme to ensure the proper installation and maintenance of these cables. Therefore, they are exempted from the rules to allow them the flexibility and freedom to carry out their tasks effectively.

Which statement is true concerning risk of collision
- A.
  
  The distance of the other vessel does not change with the same bearing
- B.
  
  Risk of collision always exist when the compass bearing does not change
- C.
  
  The distance of the other vessel is closing in with the same bearing
- D.
  
  The 2 vessels is on reciprocal heading but not a head on collision
Correct Answer
C. The distance of the other vessel is closing in with the same bearing

Explanation
When the statement says "the distance of the other vessel is closing in with the same bearing," it means that the distance between the two vessels is decreasing, and they are maintaining the same relative position to each other. This indicates that there is a risk of collision because the vessels are on a converging course.

In determining safe speed, all of the following factors shall be taken into account except one
- A.
  
  Presence of background light
- B.
  
  State of visibility
- C.
  
  The length and width of the vessel
- D.
  
  Maneuverability of your vessel
Correct Answer
C. The length and width of the vessel

Explanation
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.

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 danger

Explanation
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.

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 time

Explanation
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.

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 substantial

Explanation
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.

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 lights

Explanation
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.

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 situation

Explanation
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.

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 crossing

Explanation
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.
