If you’re financing a federally documented vessel, understanding a preferred ship mortgage is essential. A preferred ship mortgage is the most secure way for lenders to protect their interest in a vessel, and it plays a critical role in vessel financing.
In this complete guide, we’ll explain everything you need to know about a preferred ship mortgage, how it works, how to file it with the U.S. Coast Guard, and how you can complete the process yourself without paying expensive third-party services.
What Is a Preferred Ship Mortgage?
A preferred ship mortgage is a type of lien recorded against a federally documented vessel through the U.S. Coast Guard National Vessel Documentation Center (NVDC).
When a lender records a preferred ship mortgage, it becomes a legally recognized claim against the vessel under federal law. This gives the lender priority over most other claims.
A properly recorded preferred ship mortgage is essential for securing financing on documented vessels.
Why a Preferred Ship Mortgage Is Important
A preferred ship mortgage provides several key benefits:
- Protects the lender’s financial interest
- Establishes lien priority
- Enables vessel financing
- Provides legal enforcement rights
Without a valid preferred ship mortgage, lenders may not have full protection in the event of default.
When Do You Need a Preferred Ship Mortgage?
You typically need a preferred ship mortgage anytime a vessel is financed.
Common scenarios include:
- Purchasing a vessel with a loan
- Refinancing an existing vessel loan
- Using a vessel as collateral
In all of these cases, a preferred ship mortgage ensures the lender’s interest is properly recorded.
Requirements for a Preferred Ship Mortgage
To qualify as a preferred ship mortgage, several requirements must be met:
- The vessel must be federally documented
- The mortgage must be in writing
- The mortgage must include vessel details (name and official number)
- The mortgage must identify the lender and borrower
- The mortgage must be signed and notarized
Meeting these requirements ensures your preferred ship mortgage is valid under federal law.
