Documented boats

Learn about special registration requirements for boats documented with the U.S. Coast Guard.

What is a documented boat?

A documented boat is a ship with a valid marine document issued by the United States Coast Guard. The federal government uses this document to register ships of 5 net tons or more for use in times of war. Documenting your ship gives you:

  • Firm evidence of nationality for international travel
  • The right to engage in open trade between the states
  • Access to a preferred mortgage for financing the boat

How to register your documented boat

1. Gather the required documents and forms

  • A current copy of the U.S. Coast Guard Certificate of Documentation
  • A completed Vessel Title Application
  • A check or money order payable to the Department of Licensing to pay the fees

Note: We don't issue titles for documented boats. The federal government provides the ownership documents.

Calculate your boat registration fees.

2. Submit the required documents

Submit all the required documents in person at a vehicle and boat licensing office or by mail.

3. Properly display your decals and registration

When you've registered your boat, you'll get your registration and a set of decals with the assigned registration number (WN#). You'll also get Vessel Registration Number Instructions showing how to properly display the registration number and decals on your boat.

If you register by mail, you'll get them in the mail. If you register at an office, the licensing agent will give them to you before you leave.

How to remove a boat from documentation

Follow these steps to remove a boat from documentation with the US Coast Guard.

Ask the Coast Guard for a "Letter of Deletion."

1. Gather the required documents and forms

Visit a vehicle/boat licensing office and bring all of the following:

  • A copy of the Letter of Deletion from the U.S. Coast Guard
  • Cash, check, or a money order for the $38.75 fee (most offices also accept some credit and debit cards)

If ownership has changed

If the boat has changed ownership, you will also need to complete an Affidavit of Loss/Release of Interest form. All registered owners who are reflected in Coast Guard records must sign this form in the presence of a notary public.

2. Submit the required materials

Submit all the required documents in person at a vehicle and boat licensing office or by mail.
