A new wreck can be very hazardous for mariners, not only when it's exact position is unknown and is still unmarked, but even when the position is known and the wreck is properly marked.
With safety in mind, it is important to demarcate the area with a Wreck Buoy which can easily be identified with it's colour.
All designed specifications are with reference to the latest IALA recommendation O-133 on Emergency Wreck Marking Buoy (Dec 2005).
