Why it is correct
IALA leaves the special mark's shape optional, provided it does not conflict with lateral marks.
IALA World Regions: Region A covers Europe (including Spain), Africa, Oceania and Asia (except Japan, South Korea and the Philippines); when entering from seaward, keep RED (can) marks to PORT and GREEN (cone) marks to STARBOARD. Region B covers the Americas (North, Central and South), Japan, South Korea and the Philippines; lateral colours are reversed (GREEN to port and RED to starboard when entering), while keeping the same shapes (can to port, cone to starboard) and identical cardinal, isolated danger, safe water and special marks.
Why the others are not
- a) Too narrow: these are possible, but not the only ones.
- b) Too narrow.
- d) Too narrow.
How to work it out in the exam
- A special mark is known by its yellow, not its shape.
