    In a sail boat how can you make yourself more visible to vessels using radar in restricted visibility?

    • Wet the sails with sea water.

    • Raise a black diamond shape.

    • Hoist a radar reflector.

    • Proceed under power.

    Correct Answer
    A. Hoist a radar reflector.
    Explanation
    Hoisting a radar reflector in a sailboat can make oneself more visible to vessels using radar in restricted visibility. A radar reflector is designed to reflect radar signals back to the source, making the sailboat easier to detect on radar screens. This increases the chances of other vessels spotting the sailboat and helps to prevent collisions in poor visibility conditions. Wetting the sails with sea water, raising a black diamond shape, or proceeding under power may not have the same effect of enhancing visibility on radar as hoisting a radar reflector.

In this situation, it is important to stop your vessel to avoid any potential collision or misunderstanding. Stopping allows you to assess the situation and communicate with the other vessel to ensure a safe passage. Turning around and returning, going to their assistance, or calling the Marine Police may not be necessary or appropriate at this point, as the power vessel may simply need time to determine its course of action.

    A cone point down indicates:

    • A vessel being towed.

    • A trawler more than 20m in length.

    • A fishing vessel with nets extending over 150m.

    • A sailing vessel under power.

    Correct Answer
    A. A sailing vessel under power.
    Explanation
    A cone point down is a day shape used to indicate that a sailing vessel is under power. This means that the vessel is using its engine or motor instead of relying solely on wind power. The cone shape, with the point facing downwards, is easily recognizable and helps other vessels understand that the sailing vessel may not be able to maneuver as easily as when it is solely under sail.

    The inboard screen of a side light should be:

    • Green

    • Red

    • (a) or (b)

    • Black

    Correct Answer
    A. Black
    Explanation
    The inboard screen of a side light should be black. This is because the inboard screen is used to block the light from the side light, preventing it from shining in the wrong direction or causing glare. Black is the most effective color for blocking light, as it absorbs all wavelengths of light and minimizes reflection. Using any other color, such as green or red, would not be as effective in blocking the light and could potentially cause visibility issues or glare.

    What is the effect of tilting the engine back in the direction arrowed? - ProProfs

    What is the effect of tilting the engine back in the direction arrowed?

    • Forces bow up.

    • Forces bow down.

    • Slows you down.

    • Speeds you up.

    Correct Answer
    A. Forces bow up.
    Explanation
    Tilting the engine back in the direction arrowed would cause the forces to bow up. This means that the force exerted by the engine would be directed upwards, causing the front of the object to rise. This can be useful in certain situations, such as when trying to lift the front of a boat or an aircraft during takeoff. By tilting the engine back, the upward force generated can help to lift the front of the object, creating a bow-up effect.

    What is this signal? - ProProfs

    What is this signal?

    • No.1 Typhoon Signal.

    • No.3 Typhoon Signal.

    • No.9 Typhoon Signal.

    • No.10 Typhoon Signal.

    Correct Answer
    A. No.9 Typhoon Signal.
    Explanation
    The No.9 Typhoon Signal is a signal used to indicate that a typhoon is approaching and is expected to affect the area severely. This signal is raised when sustained winds of 63-117 km/h are expected or are already blowing near the area. It serves as a warning to the public to take necessary precautions and to prepare for the potential impact of the typhoon.

    You approach your mooring buoy with the wind from the North. How best to approach?

    • From windward.

    • From leeward.

    • From port side.

    • From starboard side.

    Correct Answer
    A. From leeward.
    Explanation
    When approaching a mooring buoy with the wind coming from the North, the best approach is from leeward. This means approaching the buoy from the downwind side. By approaching from leeward, the wind will be pushing the boat towards the buoy, making it easier to control and maneuver. Approaching from windward would be more difficult as the wind would be pushing the boat away from the buoy, making it harder to maintain control. Approaching from either the port side or starboard side would not be the best option as it would expose the boat to the full force of the wind, making it more challenging to dock safely.

    What is this signal? - ProProfs

    What is this signal?

    • No.1 Typhoon Signal.

    • No.3 Typhoon Signal.

    • No.9 Typhoon Signal.

    • No.10 Typhoon Signal.

    Correct Answer
    A. No.1 Typhoon Signal.
    Explanation
    The No.1 Typhoon Signal is the lowest level of typhoon warning issued by the Hong Kong Observatory. It indicates that a tropical cyclone is within 800 kilometers of Hong Kong and may affect the city with strong winds. This signal is a precautionary measure to alert the public to take necessary precautions and stay updated with the latest weather information. The No.1 signal does not necessarily mean that the typhoon will directly hit Hong Kong, but it serves as a reminder to stay prepared for any potential impact.

    You want to get your boat alongside, and she is fitted with a single right handed propeller. Do you: - ProProfs

    You want to get your boat alongside, and she is fitted with a single right handed propeller. Do you:

    • Go astern.

    • Cast off and try again.

    • Go ahead and turn rudder to port.

    • Go ahead and turn rudder to starboard.

    Correct Answer
    A. Go ahead and turn rudder to port.
    Explanation
    When a boat is fitted with a single right-handed propeller, turning the rudder to port (left) will cause the stern of the boat to swing to starboard (right). This maneuver is known as a "turning circle" or "pivot turn." By turning the rudder to port and going ahead, the boat will pivot on its own axis, allowing the bow to swing to port and bring the boat alongside. Going astern (reverse) would not be effective in this situation, and casting off and trying again would not address the issue with the propeller.
