When purchasing a power boat it is important that you declare it on the appropriate registers which record the details and ownership history of the vessel.
The British Register of Shipping - Private yachts and power boats bought with a marine mortgage are required to be registered by most finance companies.
The Small Ships Register - It is advisable but not mandatory to register a pleasure boat up to 24 metres long with the Small Ships Register. This is important if you plan to take the boat abroad as it proves the boat's nationality.
Safety Identification Scheme - By registering your boat with the UK coastguard your details will be available to Maritime Rescue Co-ordination Centres throughout the UK.
