Show the answer
Correct answer: b) With characteristic rhythms not to be confused with the very quick or quick flashes of cardinal marks.
Why it is correct
All three use white, so they are told apart by rhythm. Cardinals flash quickly; safe water and isolated danger have their own rhythms.
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) Rhythms differ.
- c) They are swapped.
- d) Both use white.
How to work it out in the exam
- White light: check the rhythm.
