How a Yacht Owner Combined São Tomé and PríncipeFlag with Second Citizenship for His Vessel

São Tomé and Príncipe not only has a citizenship program but also an open international ship registry—under its flag, vessels and yachts are registered. For a yacht owner, this creates a convenient package: a flag for the vessel and a second passport for himself in one jurisdiction. Our client came precisely for this. We explain how we combined the flag and citizenship.

Client story

Client's Story

Where they started

The client—a yacht owner—was seeking a convenient flag for vessel registration and was also considering second citizenship for himself. Learning that São Tomé and Príncipe offered both, he wanted to combine them within one jurisdiction.

Why the standard route did not work

The context here is real: São Tomé and Príncipe operates an open international ship registry, under whose flag vessels and yachts are registered in accordance with the applicable Maritime Code. It is an "open" registry—meaning a foreign owner can also register a vessel provided they meet the registry standards. For a yacht owner, such a flag can be advantageous in terms of registration and operational conditions.

What BRIDGES had to solve

Combining with citizenship completes the picture: the client obtains a second São Tomé and Príncipe passport for himself and registers his yacht under the flag of the same jurisdiction—the flag for the vessel and citizenship for the owner are thus coordinated within one country. It is important to understand that these are two separate procedures: citizenship is obtained through an investment program (fund contribution), and yacht registration follows ship registry rules; a passport does not replace registration and vice versa. However, together they provide a convenient, coordinated structure.

Why a standard answer would not do

At BRIDGES, the client came for this package: to obtain São Tomé and Príncipe citizenship for himself and coordinate yacht registration under the São Tomé and Príncipe flag, obtaining both flag and passport in one jurisdiction.

I was looking for a convenient flag for my yacht and was also thinking about a second passport. It turned out that São Tomé and Príncipe has both an open ship registry for yachts and a citizenship program. Igor brought it all together: I obtained a São Tomé and Príncipe passport for myself and registered my yacht under its flag. He honestly explained that these are two separate procedures—citizenship through the program, registration under maritime rules—but together they created a coordinated structure. Flag and passport in one jurisdiction—exactly what I wanted.

Key Considerations

Key Considerations

There was no threat—only the task of coordinating flag and citizenship. The risk lay solely in confusing two separate procedures: citizenship through the investment program and yacht registration under maritime rules. The key was to properly execute both, understanding that a passport does not replace vessel registration, and registration does not replace a passport.

That São Tomé and Príncipe has an open international ship registry (yachts);

  1. 01That a foreign owner can register a vessel provided they meet standards;
  2. 02That citizenship and registration are two separate procedures;
  3. 03That a passport does not replace yacht registration and vice versa;
  4. 04That together they provide a coordinated structure in one jurisdiction.

The logic of the solution

How the matter progressed: from checks to result

The chart is built from the facts of this matter and shows the logic of the work without decorative or unverified data.

  1. 01
    Stage 1

    We identified a cohesive package. First, we understood the request: the client needed both a convenient flag for the yacht and a second passport, preferably coordinated. São Tomé allowed us to assemble this in one jurisdiction.

  2. 02
    Stage 2

    We confirmed the reality of the ship register. We relied on the fact that São Tomé has an open international ship register under whose flag yachts are registered in accordance with the Maritime Code, including for foreign owners.

  3. 03
    Stage 3

    We separated the two procedures. We clearly explained: citizenship is granted under the investment program, while yacht registration follows the ship register rules. These are different processes and should not be confused.

  4. 04
    Stage 4

    We obtained citizenship for the owner. We made a contribution to the National Transformation Fund and obtained a second São Tomé passport for the client—citizenship for the owner themselves.

  5. 05
    Stage 5

    We coordinated yacht registration under the flag. We coordinated the registration of the vessel under the São Tomé flag in accordance with register rules, so that the yacht's flag and the owner's citizenship would be in one jurisdiction.

Takeaway. Conclusion: São Tomé has both investment citizenship and an open international ship register for yachts. These are two separate procedures, but in one jurisdiction they provide a convenient package of flag and passport.

Expert comment

The "yacht flag plus second passport" package is an uncommon but elegant request, and São Tomé is suitable for it because the country has not only a citizenship program but also an open international ship register. Under the São Tomé flag, vessels and yachts are registered in accordance with the Maritime Code, and the register is open—meaning it is accessible to foreign owners subject to compliance with standards. For a yacht owner, this is convenient: a flag for the vessel and citizenship for themselves in one jurisdiction. However, I always clearly distinguish: these are two separate procedures. Citizenship is granted under the investment program through a fund contribution, while yacht registration follows separate maritime rules in the ship register. A passport does not replace registration, and registration does not replace a passport—they should not be confused. But together they form a coordinated, cohesive structure. For this client, we obtained both a second São Tomé passport and coordinated a flag for their yacht—the flag and citizenship are in one country, exactly as they wished.
