Because ownership is recorded with the U.S. Coast Guard rather than a state registration agency, when you sell a documented vessel, every transfer must follow established federal procedures.

Whether you are transferring ownership to another individual or a business, completing the required forms correctly helps prevent unnecessary delays and protects the chain of ownership.
What Paperwork Is Legally Required to Sell a Documented Vessel?
A documented vessel transfer requires specific forms that establish the legal transfer of ownership. Federal regulations govern these transactions, making accuracy essential throughout the process. Information about ownership transfers and filing requirements can be found in the applicable regulations.
The primary document used during the transfer is the U.S. Coast Guard Bill of Sale (Form CG-1340). This form records the details of the transaction and identifies both the buyer and seller, along with the vessel information and purchase details.
The seller’s signature generally must be notarized so the transfer becomes part of a valid chain of title. Missing signatures, incomplete information, or inconsistencies between forms can delay processing and require corrections before the transfer can move forward.
Before submitting paperwork, it is helpful to verify that the information is complete, including:
- Vessel name
- Official Coast Guard number
- Hull Identification Number (HIN)
- Names of every owner shown on the Certificate of Documentation
- Complete purchaser information
- Purchase date
- Notarized signatures where required
Our online portal makes it easier to prepare and submit USCG documentation applications electronically, providing a convenient way to complete required filings while reducing common paperwork errors.
When ownership is changing, additional forms may also be necessary depending on the circumstances of the sale. Every transaction is unique, so ensuring the documents match the vessel’s ownership history helps support a smoother filing process.
Ownership Records Before a Transfer
Before ownership changes hands, reviewing the vessel’s existing records can help both parties understand the documentation already on file. Sellers often benefit from confirming that ownership information matches the current Certificate of Documentation before beginning the transfer process.
Some owners also obtain an abstract of title before completing the transaction. This record provides historical information regarding ownership and recorded instruments affecting the vessel. Reviewing these records beforehand may help identify issues that should be addressed before transfer paperwork is submitted.
Items commonly reviewed include:
- Current documented owner information
- Previously recorded ownership transfers
- Recorded mortgages
- Releases of prior liens
- Vessel identification information
Taking time to confirm these records before submitting transfer documents may reduce avoidable processing issues later.
What Information Should Sellers Confirm Before Completing the Sale?
Preparing documentation before submitting forms can help the transfer move through processing more efficiently. Since federal documentation records rely on consistency across every filing, even small discrepancies may require corrections.
Sellers should review information such as:
- Exact spelling of owner names
- Official vessel number
- Hull Identification Number
- Mailing addresses
- Dates shown on supporting forms
- Signatures on every required document
If ownership includes multiple individuals or a business entity, each required signature should appear exactly as required by the applicable documentation forms.

Steps to Sell a Documented Vessel With Greater Confidence
When you need to sell a documented vessel, taking time to prepare complete documentation from the beginning can make the overall filing process more straightforward.
Preparing carefully before submitting paperwork can reduce unnecessary delays during the ownership transfer process. While every transaction differs, following a consistent approach often helps maintain complete documentation.
Helpful preparation may include:
- Gathering all ownership documents before beginning
- Reviewing the Certificate of Documentation
- Completing the Bill of Sale carefully
- Confirming that signatures have been properly notarized
- Verifying vessel identification information
- Ensuring supporting documents are included when required

Why Must You Clear a Preferred Ship Mortgage Before Completing the Transfer?
A preferred ship mortgage represents a recorded legal interest in the vessel. Because it becomes part of the Coast Guard’s documentation records, ownership cannot always be transferred freely while an active mortgage remains outstanding.
If financing has been secured using the documented vessel as collateral, the lender’s interest generally remains attached until it has been properly released. That release typically occurs through filing a Satisfaction of Mortgage (Form CG-4593), allowing documentation records to reflect that the lender’s interest has been discharged.
An unresolved mortgage may create complications during a transfer because the documentation records continue to show an existing lien against the vessel.
Common situations that should be addressed before filing transfer paperwork include:
- Outstanding preferred ship mortgages
- Previously recorded liens awaiting release
- Incomplete satisfaction filings
- Ownership records that do not match current documentation
Making sure these matters have been resolved before submitting ownership transfer paperwork can help avoid interruptions during processing.
How Mortgage Documentation Affects the Transfer Timeline
Mortgage-related paperwork often influences how quickly ownership records can be updated. Before filing transfer documents, it is beneficial to confirm that every required mortgage document has been properly completed and submitted.
If a lender’s recorded interest remains active, processing may be delayed until the appropriate release has been recorded. Reviewing documentation beforehand can help identify whether additional paperwork is necessary before ownership changes hands.
Some documents commonly associated with mortgage-related transfers include:
- Recorded mortgage instruments
- Satisfaction of Mortgage (Form CG-4593)
- Ownership transfer forms
- Supporting documentation requested for the filing
Although each transaction differs, ensuring that mortgage records accurately reflect the vessel’s current status can help minimize unnecessary interruptions during processing.

Keeping Your Coast Guard Records Current After the Transfer
After ownership has officially changed, maintaining accurate federal records remains important. Once the transfer has been processed, future filing requirements may arise depending on the vessel owner’s circumstances.
For example, documentation renewal is necessary to maintain an active Certificate of Documentation for eligible vessels. Keeping records current helps ensure that ownership information remains accurate within federal documentation records.
Owners should also remember to update documentation whenever information affecting the Certificate of Documentation changes. Maintaining current records helps support accurate ownership information throughout the vessel’s documented life.

Additional Records That May Support Future Transactions
Accurate documentation today can simplify future ownership transfers, financing transactions, or other filings involving the vessel. Maintaining organized records allows owners to locate important information more easily whenever additional documentation becomes necessary.
Some owners also perform a vessel documentation search before future transactions to verify the current federal documentation status reflected in public records.
Depending on the circumstances, owners may wish to retain copies of:
- Bills of Sale
- Mortgage release documents
- Certificates of Documentation
- Notarized transfer forms
- Correspondence related to completed filings
