Buying a U.S.-Flagged Yacht in Mexico: How to Keep U.S. Coast Guard Registration

One of the most common — and misunderstood — scenarios in international yacht sales is this:

The boat is physically located in Mexico, but it is U.S.-flagged, U.S. Coast Guard documented, and the buyer wants to keep it that way.

The good news?
This is very common, completely legal, and very manageable — if it’s handled correctly.

Here’s how it works, and what buyers should know.


1. Location Does NOT Determine Registration

A yacht’s flag and registration are based on ownership and documentation — not where the boat is parked.

A yacht can be:

  • Sitting in Ensenada, La Paz, Cabo, or Puerto Vallarta
  • And still be 100% U.S.-flagged and USCG documented

As long as:

  • The vessel is owned by a U.S. citizen or qualifying U.S. entity
  • And it remains properly documented with the U.S. Coast Guard

Its U.S. status stays intact.

Mexico does not require U.S.-flagged yachts to re-register locally.


2. The Vessel Does NOT Need to “Leave Mexico” to Transfer Ownership

A major misconception is that the boat must return to the U.S. to complete a sale.

That is false.

The sale can be completed while the yacht remains in:

  • Ensenada
  • La Paz
  • Cabo
  • Or anywhere in Mexican waters

The Coast Guard documentation is transferred by:

  • A U.S. Bill of Sale
  • A new USCG application
  • And a closing process handled by a documentation agent

The boat never has to move.


3. The Buyer Applies for New USCG Documentation

After closing, the buyer files:

  • Application for Documentation
  • Proof of U.S. citizenship or qualifying entity
  • The notarized Bill of Sale

The Coast Guard then:

  • Cancels the seller’s documentation
  • Issues new documentation in the buyer’s name

The vessel never loses its U.S. flag.


4. Mexican Temporary Import Permit (TIP)

Because the yacht is physically in Mexico, it must have a Temporary Import Permit (TIP).

Important facts:

  • The TIP belongs to the owner, not the boat
  • When the boat is sold, the old TIP must be canceled
  • The new owner must apply for a new TIP

This is handled by:

  • A Mexican customs agent (or online via Banjercito)
  • Often coordinated during closing

This has no impact on U.S. registration.


5. No Mexican VAT or Import Tax Is Triggered

When you buy a U.S.-flagged yacht in Mexico and keep it foreign-flagged:

  • You do not pay Mexican import tax
  • You do not pay Mexican VAT
  • You do not register it in Mexico

As long as it stays under a TIP, it remains a foreign yacht temporarily cruising Mexico.


6. Why Buyers Prefer to Keep U.S. Documentation

Keeping a yacht U.S.-flagged provides major advantages:

✔ Easier financing
✔ Easier resale in the U.S. market
✔ Better insurance options
✔ No foreign registry compliance
✔ No VAT exposure
✔ Simpler exit back to the U.S.

This is why most U.S. buyers choose to keep their yachts U.S. documented even when cruising Mexico for years.


7. How a Proper Closing Is Structured

A clean Mexico-based U.S. yacht closing typically includes:

  • U.S. Coast Guard documentation transfer
  • U.S. Bill of Sale
  • Escrow handling of funds
  • Cancellation & re-issuance of TIP
  • Insurance binder before ownership transfer
  • Closing coordinated by broker + documentation agent

From the buyer’s perspective, it feels exactly like buying a boat in San Diego — even though the boat is in Mexico.


Final Thoughts

A yacht being physically in Mexico does not change its nationality.

If the boat is:

  • U.S. Coast Guard documented
  • And owned by a U.S. buyer

It remains a U.S. vessel — no matter where it is cruising.

Handled correctly, buying a U.S.-flagged yacht in Mexico is smooth, tax-efficient, and one of the smartest ways to acquire a cruising yacht for Baja, Cabo, and beyond.
