How to join the safety identification scheme (CG66)
The voluntary safety identification scheme (CG66) is run by the Maritime and Coastguard Agency (MCA). It provides the coastguard with vital information about your boat in an emergency.
If you register your boat through the CG66 scheme and you get into trouble, you just need to provide the basic information about your boat and situation in a Mayday call.
The coastguard can get more information about your boat, like what it looks like and the safety equipment you are carrying, from the CG66 database. This information helps the coastguard respond to your call.
You can join the scheme at the following link:
The CG66 database is accessible to Maritime Rescue Co-ordination Centres (MRCCs) throughout the UK.
You need to update your boat's details every two years.
