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.

Colour described on charts as:-
BYB- for Black over Yellow over Black.

Memory Aids:-

  • The two arrows point in the opposite direction to the West Cardinal buoy.
  • The arrows always point to the black sections - in this case the upper and lower sections
  • East is at “Three o’clock” on the Compass - so three flashes.
