1. Start with the vessel, not the paperwork
The register treats a pleasure yacht, a smaller boat and a merchant ship differently, and the difference is set by use and size rather than by what the owner calls the vessel. Working out which of the three the vessel actually is decides which survey track, which certificates and which timeline apply.
2. Pleasure or commercial changes everything downstream
Independently of vessel type, a craft used only by its owner is registered for pleasure use; one operated for reward — charter, cargo, passengers — is registered commercially and carries the certification that goes with it. The two regimes are not interchangeable without converting the registration.
3. Size and tonnage set the certification track
A small privately used craft carries a proportionate survey and document file. Once a vessel is large enough to require tonnage measurement, or is operated commercially, the full set of statutory surveys and certificates applies. This is assessed vessel by vessel, not by a fixed length rule alone.
4. Ownership sits above all three
Whatever the vessel type, most international owners register through a Maltese owning company rather than in their own name, for the same reasons across yacht, boat and ship: an eligible Maltese owner, separated liability, and a share transfer instead of a vessel transfer if it is later sold.
5. Two-stage registration applies across the board
Provisional registration, typically within 24–48 hours, then permanent registration once survey and measurement are complete — the same sequence for a tender, a superyacht and a merchant ship, only the survey scope changes.
6. Already flagged somewhere else?
Reflagging works the same way regardless of vessel type: the outgoing registry deletes the vessel, Malta registers it, and the two are sequenced to minimise time without a flag.
7. What follows registration differs by class
A privately used boat's ongoing obligations are lighter than a commercial yacht's, which are lighter than a merchant ship's ISM, ISPS and MLC 2006 cycles. The renewal calendar is set at permanent registration, scaled to the vessel's class.
