Safe Water Mark

Safe Water Mark, as defined by the International Association of Lighthouse Authorities, is asea mark used in maritime pilotage to indicate the end of a channel implying that open, deep and safe water lies ahead. The marker is also sometimes known as a Fairway Buoy.

It is recognisable by its red and white vertical stripes and commonly bears a top-sign in shape of a red ball. Lighted buoys flash morse code “A”.

In the United States, safe water marks have the initials of their associated waterways or localities printed on them.

Lighted buoy flashes morse code “T” (one long flash) with intervals of 6 seconds
