When two power-driven vessels are crossing so as to involve risk of collision :-
Correct Answer
B. The vessel which has the other on the starboard side shall give way
Explanation
When two power-driven vessels are crossing paths in a way that there is a risk of collision, the vessel that has the other vessel on its starboard side (right side) should give way. This is because the International Regulations for Preventing Collisions at Sea (COLREGs) state that when two vessels are crossing, the vessel on the starboard side has the right of way and the vessel on the port side (left side) should give way. This rule helps to avoid confusion and ensures that vessels can safely navigate and pass each other without colliding.
3.
A vessel engaged in fishing when crossing the path of a power-driven vessel, so as to involve risk of collision :
Correct Answer
A. Power-driven vessel should give way to the fishing vessel
Explanation
When a power-driven vessel crosses the path of a fishing vessel, it is the responsibility of the power-driven vessel to give way to the fishing vessel. This is because the fishing vessel is engaged in a specific activity (fishing) and may have limited maneuverability. Therefore, the power-driven vessel should take necessary actions to avoid a collision and allow the fishing vessel to continue its fishing operations safely.

When a vessel is overtaking another at night, she would be able to see the following lights of the vessel being overtaken:
Correct Answer
C. One white light only (stern light)
Explanation
When a vessel is overtaking another at night, she would be able to see only one white light, which is the stern light. This light is located at the back (stern) of the vessel being overtaken and helps the overtaking vessel determine the position and movement of the vessel ahead. The green and red lights (side lights) are not visible when overtaking, as they are positioned on the sides of the vessel. The masthead light, which is also visible from the front of the vessel, is not relevant in this situation.
7.
At night, a power-driven vessel sees a red and a green light only, directly ahead. What action does she take?
Correct Answer
C. Take appropriate action to avoid collision, as the vessel ahead is a sailing vessel.
Explanation
The red and green lights indicate that the vessel ahead is displaying the sidelights, which are typically used by sailing vessels. Therefore, the power-driven vessel should take appropriate action to avoid a collision with the sailing vessel. This may include altering course, reducing speed, or taking any other necessary actions to ensure a safe distance between the two vessels.
