Five questions that separate a legal operator from a hopeful one

You are not auditing anyone. You are asking five factual questions and watching whether they come back as facts. That distinction matters, because it is what makes the exercise reasonable to do by email before a deposit.

One: what flag does the yacht fly?

This is the question everything else hangs off, and it has a one-word answer. Thai flag means a domestic regime and no superyacht licence involved. A foreign flag means the licence question is live if the hull is 24 metres or longer. An operator who does not know the flag of a yacht they are selling you does not have a close relationship with that yacht.

Two: what is the licence reference and when does it expire?

Ask for both. The expiry is the more revealing half, because the licence runs for one year and your charter has a date. A licence expiring three weeks before you sail is a problem that is easier to raise now than at the pier.

Three: who is the fiscal representative?

Every licensed foreign-flagged charter runs through a Thai fiscal representative who obtains the licence, declares the yacht's movements and pays the tax. It is a named company. If nobody can name it, the structure it belongs to probably is not there.

Four: who is named in the contract?

A charter agreement that names only the broker leaves you with a claim against an agent rather than against the party that owes you a yacht. A MYBA-form contract names the yacht, the owning company and the charterer. If the offered contract does not, ask why, and read what it does say about cancellation and about who carries the risk if the yacht is unavailable.

Five: how is the VAT shown?

Tax on a licensed charter is 7 percent VAT on the fee plus 5 percent corporate income tax on the revenue. The VAT should appear as its own line against a Thai tax number. This is the question that is hardest to answer smoothly from outside the system, because it asks for a number that only exists if the registration behind it exists.

What a good answer sounds like

Short. Specific. Slightly bored. Compliant operators answer these questions regularly and have the details to hand. What you are listening for is the opposite: a long answer about how established the company is, an assurance that everything is completely normal in Thailand, or a redirection to how quickly the dates are going.

None of this applies to a Thai-flagged day charter out of Chalong, which is a different and entirely legitimate part of the market. Question one sorts that out in a word, which is why it is question one.
