This only pertains to Federal documentation through the United States Coast Guard. In regards to State registration in Montana, refer to state rules and the appropriate governing body.


Documentation must be renewed every year. Through our site, vessel owners with a “Recreational” endorsement will have the option to renew their documentation for up to five years in advance.


Renewing less than 60 days before the expiration date is recommended. Renewing more than 60 days prior to expiration will issue renewal with a new expiration and issuance date, thus shortening the documentation’s period of validity.


Vessel owners can renew their documentation up to 30 days after the expiration date.


After that period, vessel owners cannot “renew” their documentation. However, they can reinstate it. Vessel owners can use this link to reinstate their Certificate of Documentation.
