This is a national form of boat registration. United States Coast Guard Documentation provides for unhindered commerce between states, admits vessels to restricted trades (such as the fisheries and coastwise trade), and provides conclusive evidence of nationality.


Vessels that are documented do not have titles. Instead, they maintain Certificates of Documentation. Depending on the laws in your state, your vessel may need to be registered with the state as well.


Vessel financing has been enhanced through the availability of preferred mortgages on documented vessels since 1920.


U.S. Coast Guard documentation has to be renewed every year. However, this can be renewed for 1-5 years from the date of issuance. Vessel owners can use this link to renew vessel documentation.
