Form CG-1258 is the primary application used by the United States Coast Guard’s National Vessel Documentation Center for several documentation-related transactions. The form serves as a central document for recording ownership information, vessel details, and other important facts that become part of a vessel’s official record.

The form may be used for:
- Initial vessel documentation applications
- Certain ownership updates
- Recording changes to vessel information
- Changes involving owner details
- Requests related to documented vessel status
- Certain documentation transactions recognized by Coast Guard regulations
Because the application collects substantial information regarding both the vessel and its owners, it often serves as the foundation for many documentation filings.
For vessel owners seeking a convenient filing experience, our online portal allows applicants to complete and submit required documentation forms through a secure digital process rather than relying solely on traditional paper submissions.
Many owners first encounter this form during a transfer of ownership involving a documented vessel. In those situations, accurate information is essential because the Coast Guard record must reflect the vessel’s current ownership status.
