Cardinal Buoys can be either Quick Flashing or Very Quick Flashing so that they can be distinguished when used in multiples - perhaps protecting a long sand bank for example.

Memory Aids:-

  • As far as the arrows are concerned, “west” is like a “waist” - but some people also say that it is like a “W” on its side.
  • The arrows always point to the black sections - in this case the central section
  • West is at “Nine o’clock” on the Compass - so nine flashes.
