Choose mode in which you want take CES test:

Start test
A prescribed by the IALA Maritime 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.
Next question
A prescribed by the IALA Maritime 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.
