  1. Question 1

    A prescribed by the IALA Buoyage System, if you are proceeding down a channel AGAINST the Conventional Direction of Buoyage and you come across a yellow Special Mark with a can shape, how will you pass it?
    • Leave it to port.
    • Leave it to starboard.
    • Pass either side - it is a Special mark and there is safe water all round.
    • Refer to the Sailing Directions for further instructions.

  2. Question 2

    A prescribed by the IALA Buoyage System, you are proceeding down a channel AGAINST the Conventional Direction of Buoyage and you come across a West Cardinal Mark. How will you pass it and why?
    • I will pass to the West of it. Cardinal marks are not used in conjunction with Direction of Buoyage, so this has no bearing on my decision.
    • I will pass to the East of it, as going against the Direction of Buoyage, my passage is reversed.
    • There must be a mistake. I should not encounter a Cardinal Mark in or near a channel. I will drop anchor and investigate further.
    • It does not matter which side I pass it. A Cardinal Buoy in a channel has clear water all round it.

  3. Question 3

    As prescribed in the IALA Buoyage System, what rhythm may the light of this mark display?
    • Any that is not used for Cardinal, Isolated Danger and Safe Water marks.
    • Isophase.
    • Any, that is not used for a red or green light under the IALA Buoyage System.
    • VQ(6)+LFI.

  4. Question 4

    As prescribed in the IALA Buoyage System, where would you find spherical-shaped buoy?
    • On the port side of a channel.
    • On the starboard side of a channel.
    • In the middle of a channel.

  5. Question 5

    At what rate will a "Quick Flash" light used on a buoy of the IALA Buoyage System be flashing?
