No proof of ownership is needed by the USCG if you don't own the vessel. All you need is signatures from the captain or the vessels owner.
No. If you are not the owner of the vessel, someone with knowledge of your service must attest to its accuracy and validity in the proper location on the form by signing it and completing the associated required information.
In other words, those who do not own a vessel must obtain letters or other evidence from the captain or the owners of the vessels listed.

If you are signing as the owner of a corporation that owns the vessel, you must include a copy of proof of ownership of the company, such as a copy of the articles of incorporation.
If you are the owner of a vessel on which you are claiming service, you must also submit proof of ownership for that vessel. Acceptable proof of ownership may include:
1. Title
2. Registration (state registered vessels) 3. Certificate of Documentation (U.S. Coast Guard registered vessels) 4. Proof of insurance (which clearly identifies the vessel)
5. Bill(s) of sale.
