  • 8. 

    Vessel "X" is overtaking vessel "Y" on open waters and will pass without changing course. Vessel "X" ___________.

    • Should sound two short blasts

    • Should sound the danger signal

    • Should sound one long blast

    • Will not sound any whistle signals

    Correct Answer
    A. Will not sound any whistle signals
    Explanation
    When a vessel is overtaking another vessel on open waters and will pass without changing course, it is not required to sound any whistle signals. Whistle signals are typically used to communicate the intentions and movements of vessels to avoid collisions. In this situation, since vessel "X" is passing without changing course, there is no need for any whistle signals as there is no risk of collision.

    Rate this question:

  • 9. 

    Whenever a course alternation is made to avoid collision, it should be:

    • Any of the choices is correct

    • A large change

    • Supplemental by speed change

    • A succession of small changes

    Correct Answer
    A. A large change
    Explanation
    When making a course alteration to avoid collision, it is important to make a large change in the course. This is because a small change may not be sufficient to avoid the collision, especially if the other vessel is also making a course alteration. A large change in the course increases the chances of creating a safe distance between the two vessels. Additionally, making a large change in the course can help to clearly communicate the intention to the other vessel, reducing the risk of misinterpretation. Therefore, a large change is the most effective and recommended approach in such situations.

    A vessel heading SSE is on a course of:

    • 157.5deg.

    • 135.0deg.

    • 180.0deg.

    • 112.5deg.

    Correct Answer
    A. 157.5deg.
    Explanation
    The vessel heading SSE means it is moving in the direction of south-southeast. The angle between the vessel's course and the south direction is 22.5 degrees (180 degrees - 157.5 degrees). Since the vessel is heading SSE, the course angle is in the clockwise direction from the south. Therefore, the correct answer is 157.5 degrees.

    • Red and green lights are not used

    • It is one of those listed under Annex IV of the Collision Regulations

    • The signal cannot be mistaken for a signal authorized by the Rules

    • The vessel signals such intentions over the radiotelephone

    Correct Answer
    A. The signal cannot be mistaken for a signal authorized by the Rules
    Explanation
    A vessel may use any sound or light signals to attract the attention of another vessel as long as the signal cannot be mistaken for a signal authorized by the Rules. This ensures that there is no confusion or misinterpretation of signals, which could potentially lead to accidents or misunderstandings between vessels. It is important for vessels to use signals that are distinct and not easily confused with the signals specified in the Collision Regulations to maintain clear communication and avoid any potential dangers at sea.
