This is important to ensure the safety of both vessels and to prevent any potential collision. By taking this action, the power-driven vessel "I" can maintain a safe distance from the fishing vessel "II" and reduce the risk of any accidents or interference with the fishing operations.

This is a requirement according to international regulations to indicate to other vessels that there is a tow line in the water. The diamond shape is easily recognizable and helps to warn other vessels to keep a safe distance and avoid any potential collisions.

    When a fishing vessel is anchored in restricted visibility, it is required to emit a fog signal to indicate its presence. The required fog signal for a fishing vessel engaged in fishing is one prolonged followed by two short blasts, repeated every 1 minute. This signal helps to alert other vessels in the vicinity and prevent any potential collisions.

  • 13. 

    BOTH INTERNATIONAL & INLAND Which statement is TRUE concerning two sailing vessels?

    • A.

      A sailing vessel with the wind forward of the beam on her port side shall keep out of the way of the sailing vessel with the wind forward of her beam

    • B.

      When both vessels have the wind on the same side, the leeward vessel shall keep out of the way

    Correct Answer
    A. A sailing vessel with the wind forward of the beam on her port side shall keep out of the way of the sailing vessel with the wind forward of her beam
    Explanation
    When two sailing vessels have the wind forward of the beam on their port side, the vessel on the starboard tack (with the wind forward of its beam on the starboard side) has the right of way and the vessel on the port tack (with the wind forward of its beam on the port side) must keep out of the way. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS) Rule 12, which states that a vessel on the port tack shall keep out of the way of a vessel on the starboard tack.

    Correct Answer
    A. Lights of one power driven vessel
    Explanation
    When a vessel is rigidly connected to another vessel in a composite unit and is pushing ahead, it will show the lights of one power-driven vessel. This means that the vessel will display the required navigation lights for a power-driven vessel, which typically include a white masthead light, a green starboard light, and a red port light. These lights are used to indicate the vessel's position and direction of travel to other vessels in order to prevent collisions at sea.

    INT'L & INLAND The rules require that a stand-on vessel SHALL take action to avoid collision when she determines that:

    • A.

      Collision cannot be avoided by the give-way vessel's maneuver alone

    • B.

      The other vessel is not taking appropriate action

    • C.

      Risk of collision exists

    • D.

      The other vessel will cross ahead of her

    Correct Answer
    A. Collision cannot be avoided by the give-way vessel's maneuver alone
    Explanation
    When a stand-on vessel determines that a collision cannot be avoided by the give-way vessel's maneuver alone, it is required to take action to avoid the collision. This means that if the give-way vessel's actions alone are not sufficient to prevent a collision, the stand-on vessel must also take evasive action. This ensures that both vessels are actively working to avoid a potential collision and promotes safe navigation at sea.

    Correct Answer
    A. High seas and all waters connected and navigable by seagoing vessels
    Explanation
    International rules apply to the high seas and all waters connected and navigable by seagoing vessels. This means that the rules and regulations set by international agreements and organizations, such as the International Maritime Organization (IMO), apply to these areas. These rules govern various aspects of maritime navigation, safety, and environmental protection to ensure a standardized and coordinated approach across different countries and regions.

    Explanation
    INLAND rules apply to the waters of the United States and Canadian waters of the Great Lakes, as long as there is no conflict with Canadian law. This means that these rules are applicable in these specific regions and must be followed by vessels navigating in these waters, unless there is a conflict with Canadian law.

    Vessels under _______ may not impede the passage of other vessels in a narrow fairway

    • A.

      20 meters

    • B.

      10 meters

    • C.

      30 meters

    • D.

      50 meters

    Correct Answer
    A. 20 meters
    Explanation
    Vessels under 20 meters may not impede the passage of other vessels in a narrow fairway. This means that if a vessel is less than 20 meters in length, it must give way to larger vessels and allow them to pass through the narrow fairway without obstruction. This rule helps to ensure the safe and efficient movement of vessels in narrow waterways, preventing any potential accidents or delays.

    WTF QUESTION Which factor is listed in the rules as one which must be taken into account when determining safe speed?

    • A.

      Construction of the vessel

    • B.

      Maneuverability of the vessel

    • C.

      The experience of personnel

    • D.

      All of the above

    Correct Answer
    B. Maneuverability of the vessel
    Explanation
    When determining safe speed, one of the factors that must be taken into account is the maneuverability of the vessel. This means considering how easily the vessel can change direction or navigate through various conditions. The maneuverability of the vessel can be affected by factors such as its size, design, propulsion system, and any external factors that may impact its ability to maneuver effectively. Therefore, it is important to consider the maneuverability of the vessel when determining a safe speed to ensure that it can safely navigate and respond to any potential hazards or obstacles.
