There is a new experimental wreck buoy

A pillar of spar buoy, the size dependent upon the situation.

[b]Colour[/b]
Between 4 and 8 vertical blue and yellow stripes, these stripes will be of equal width. The abbreviation of the colour will be BuY.

[b]Light[/b]
An alternating blue and yellow flashing light with a nominal range of 4 nautical miles, the blue and yellow 1 second flashes are alternated with an interval of 0.5 seconds. Bu1.0s+0.5s+Y1.0s+0.5s= 3.0s

[b]Topmark[/b]
The top mark, if fitted, is to be a standing/upright yellow cross. (This shape is new for the IALA Buoyage System.)

These buoys will remain on station until:

• The wreck is well known and has been promulgated in nautical publications;
• The wreck has been fully surveyed and exact details such as position and least depth
above the wreck are known;
• A permanent form of marking of the wreck has been carried out.
