Buyer's guide

Flag and registration: where your yacht is registered

Every yacht that goes to sea internationally is registered with a flag state, and that registry decides which rules she is built and run to, which documents prove her ownership, and how easily she can be financed, chartered or sold. When you buy a yacht you either keep her existing flag or move her to a new one. This guide explains how registration works and how the registries most often seen on larger yachts differ.

Updated September 2026

What registration does

Registration does three things. It gives the yacht a nationality, which determines the law that applies aboard and the protection of that state at sea. It records her ownership and, on the registries that allow it, any mortgage over her, which is how a lender takes security. And it brings the yacht under the flag state's safety, manning and survey rules, which differ between private and commercial use.

In the British system the property in a ship is divided into 64 shares. Owners are registered as holding those shares, and the regulations allow up to five people to be registered jointly as owners of a ship or of any share in her. The same tradition runs through the registries of the Red Ensign Group, the family of British registries that includes those of the Crown Dependencies and several Overseas Territories.

Private or commercial registration

The most important choice is often not the country but the use. A yacht registered as private is for her owner's own use and may not carry paying guests. A yacht that charters must be registered and certified for commercial use, which for larger yachts means meeting a code of construction, equipment and manning standards and being surveyed against it. For the Red Ensign registries that is the REG Yacht Code, whose Part A covers yachts of 24 metres and over in commercial use that carry no cargo and no more than 12 passengers.

Moving a yacht from private to commercial registration is possible, but it is a project rather than a form: a survey against the code, often modifications, and the manning and safety management that commercial operation requires. If charter income matters to you, the yacht's current certification is one of the first things we check.

The registries most often seen on larger yachts

The United Kingdom's register has four parts. Part 1 is the full register for commercial and pleasure vessels, and registration there allows a marine mortgage to be registered and a yacht to spend more than six months outside the UK. Part 3, the Small Ships Register, is a simpler register for boats under 24 metres whose owners live in the UK for at least 185 days a year, and a business cannot use it.

The Cayman Islands register is a Category 1 member of the Red Ensign Group, which means it can register vessels of any size, and a Cayman yacht is a British ship. It is widely used for large yachts owned through companies, it registers mortgages, and it offers interim registration and registration of yachts under construction.

Malta's register is that of an EU member state and is often chosen for yachts that will be based in the Mediterranean. It distinguishes pleasure yachts, for private use only, from commercial yachts, which are certified under Malta's own yacht codes before they may trade. The Marshall Islands register, administered for the Republic by a private company, registers private yachts, private yachts with limited charter, and commercial yachts, and requires ownership through a Marshall Islands entity or a qualified foreign maritime entity.

Changing flag when you buy

If you keep the yacht's current flag, her registration is transferred into your name, or the name of your owning company, on the strength of the Bill of Sale and the registry's own forms. If you move her to a new flag, the old registry first issues a deletion certificate confirming that she has been removed from it and showing whether any mortgage was registered, and the new registry registers her on the Bill of Sale, the deletion certificate and its own survey and tonnage requirements. For a new yacht, the Builder's Certificate takes the place of a previous Bill of Sale. Many registries grant provisional registration first, so that she can sail while the original documents are gathered.

The flag also interacts with VAT and with where you can keep the yacht. Flying an EU flag does not by itself make a yacht VAT paid, and registration outside the EU is one of the conditions of temporary admission for owners established outside the EU. We make sure the flag decision is taken alongside the VAT decision, not after it.

Who chooses, and how we help

The choice of flag depends on your nationality and residence, whether the yacht will be owned personally or through a company, where she will cruise, whether she will charter, and how the purchase is being financed. There is no single right answer, and it is one of the decisions where specialist advice is worth taking early.

We co-ordinate the registration with the closing, so that the documents the new registry needs are specified in the contract and delivered at the handover, and we introduce you to registration agents and maritime lawyers who handle the filing.

Questions buyers ask

Does the flag decide whether VAT has been paid?

No. VAT status depends on whether EU VAT has been accounted for and whether the yacht has stayed in the EU, not on the flag she flies. The flag does matter for temporary admission, which requires registration outside the EU.

What is a deletion certificate?

A document from the yacht's previous registry confirming that she has been removed from it and showing whether any mortgage was registered. A new registry will normally require it before registering her permanently.

Can a yacht registered as private be chartered?

Not as a normal commercial charter. A yacht that charters must be registered and certified for commercial use under her flag's rules, which for larger yachts means a survey against a yacht code and commercial manning.

Can I own the yacht through a company?

Yes, and for larger yachts it is common. Each registry sets out which owners and companies may register; some require a company formed in that jurisdiction. Your lawyer will advise on the structure.
