Correct answer: a) Cardinal marks

Why it is correct

A cardinal says which quadrant holds the deepest or safest water. So you pass on the side of its name.

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

  • b) They mark channel sides.
  • c) Water all round.
  • d) They mark a single danger.
