A Preferred Ship Mortgage gives your lender priority lien status on your documented vessel, which is often required by banks and finance companies for boat loans. Filing it correctly with the National Vessel Documentation Center protects the lender’s interest and is recorded in the official vessel documentation records.
You no longer need a third-party service — the entire filing is handled electronically through the NVDC eStorefront.
This post explains the requirements, step-by-step process, and includes a powerful AI prompt to guide you through every detail.
What Is a Preferred Ship Mortgage?
It is a recorded security interest in the “whole” of the vessel. To qualify as “preferred,” it must meet specific USCG rules (46 CFR Part 67), including proper identification of the vessel, a definite amount of indebtedness, and notary acknowledgment.
There is no official government mortgage form, but you should use the optional CG-5542 (Application for Filing) attached to your actual mortgage document.
Key Requirements
- The vessel must have a valid Certificate of Documentation (or pending initial application).
- The mortgage must be signed by the owner(s) and acknowledged by a notary.
- Include: vessel name, official number (or hull number), addresses of mortgagor and mortgagee, definite sum of indebtedness.
- Filing fee: $4.00 per page (double-sided pages count as two). The CG-5542 itself is not charged per page.

Your Ready-to-Use AI Prompt:
“I need to file a Preferred Ship Mortgage (or related instrument) on my USCG documented vessel through the NVDC eStorefront. Guide me step-by-step: required documents, how to properly complete and use the CG-5542 form, exact wording and elements the mortgage must include (vessel description, indebtedness, signatures), upload requirements, fees, and common mistakes to avoid. Ask for my vessel name, official number, and mortgage details, then create a customized filing checklist.”
Additional Tips: Always file the mortgage after the vessel is documented (or simultaneously with initial documentation). If you later pay off the loan, you’ll need to file a Satisfaction/Release of Mortgage.
Conclusion: Recording a Preferred Ship Mortgage properly gives your lender the legal protection they need while keeping the process simple and low-cost through eStorefront. Use the AI prompt above to make sure your filing is perfect on the first try.
