46 CFR 67.163 - Renewal of endorsement.
(a) Requirement for renewal of endorsement. Endorsements on Certificates of Documentation are valid for one year. Prior to the expiration of that year, the owner of a vessel which is not exempt from the requirement for documentation under paragraph (c) of § 67.9 must apply for renewal of the endorsement(s) by complying with paragraph (b) of this section. The owner of a vessel exempt from the requirement for documentation under paragraph (c) of § 67.9 must either:
(2) Place the Certificate of Documentation on deposit in accordance with § 67.165.
(b) Renewal application. The owner of a vessel must apply for renewal of each endorsement by executing an original Notice of Expiration (CG-1280) or Final Notice After Expiration (CG-1280-B) certifying that the information contained in the Certificate of Documentation and any endorsement(s) thereon remains accurate, and that the Certificate has not been lost, mutilated, or wrongfully withheld. The completed CG-1280 or CG-1280-B must be forwarded to the Director, National Vessel Documentation Center.
(c) Requirement to affix decal. The owner must affix the renewal decal to the Certificate of Documentation. The presence of a current renewal decal is evidence that the endorsement has been renewed.
