Answer:

After a vessel is registered, any changes that would affect the ‘Certificate of British Registry’ must be notified to the VISR. If registered owners have changed address, they must notify the Registry of the change by written correspondence. As the production of the Certificates is fully computerized any change in the primary details includes the issue of a new certificate. That way no manual alteration appear on the face of the certificate. Therefore in such cases, the current certificate of registry must be returned for cancellation.
