California Code, Vehicle Code - VEH § 9917

Whenever application is made to the department for a transfer of ownership of a vessel to a new owner or legal owner and the applicant is unable to present the certificate of ownership issued for the vessel by reason of the same being lost or otherwise not available, the department may receive the application and examine into the circumstances of the case and may require the filing of affidavits or other information, and when the department is satisfied that the applicant is entitled to a transfer of ownership, the department may transfer the ownership of the vessel, and issue a new certificate of ownership, and certificate of number to the person or persons found to be entitled thereto.
