This service can be used to register a boat into your name / family name and address. You will be asked to declare that your are the current registered keeper of the boat in order to obtain a measurement certificate in your name. This is not to say that the measurement certificate is a proof of legal ownership of any boat.
You can update other details such as Boat name and Home Sailing Club, but not any measurement details. If measurement information has changed for your boat, please contact technical@rya.org.uk
On completion of the process you will receive an email with your certificate attached. This can take up to 30 minutes to come through.
