Q

What is an Emergency wreck marking bouy?

A

Designed to provide high visual and radio aid to navigation recognition. It is placed as close to the wreck as possible, or in a pattern around the wreck, and within any other markers that may be subsequently deployed.
The emergency wreck marking bouy is maintained in position 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 is known
* A permanent form of marking of the wreck has been carried out

Color: Equal number and dimensions of yellow and blue stripes (min 4 max 8)
Shape: Pillar or Spar, size dependent on location
Light: Fitted with an alternating blue and yellow occulting light with a nominal range of 4NM where the blue and yellow 1 second flashes are alternated with an interval of 0.5 seconds. If multiple lights are deployed, then the lights should be synchronized
Topmark (if fitted): Standing Yellow cross
Consideration should be given to the use of racon Morse “D” and/or AIS transponder (AIS, Virtual AIS, Synthetic AIS)

I would stop the vessel, inform the vessel and I would look for any marine information services (navtex, radio or sat-c)

21
Q

What is an ODAS Bouy?

(Special mark)
Ocean Data Acquisition System
May be as much as 12m in diameter and 2-3m in height
