Fill out an online form to register your boat’s details with the UK coastguard. This is a free service for owners and skippers of all types of leisure vessels and small craft.
Register your boat with the UK coastguard using the Maritime and Coastguard Agency’s voluntary safety scheme (CG66)
Your details will be available to Maritime Rescue Co-ordination Centres (MRCCs) throughout the UK. This will give them the information they need to mount a search and rescue operation if you get into difficulty.
You need to update your details every 2 years.
