Cayman Islands yacht registration runs through the Cayman Islands Shipping Registry (CISR), operated by the Maritime Authority of the Cayman Islands (MACI), and can be completed within 24 hours once the registry has received the complete documentation. The initial fee is USD 1,750 for a yacht up to 400 GT under the schedule in force since 1 April 2026 (CISN 04/2026), and the yacht becomes a British ship, holding a Certificate of British Registry.
The CISR is a Category 1 member of the Red Ensign Group — alongside the UK, Bermuda, the BVI, Gibraltar and the Isle of Man — and presents itself as a registry for vessels of all sizes and classes. This page covers who qualifies as an owner, the five official steps, the registration types, what “George Town” on the transom means, the 2026 fees and the survey requirements.
Cayman vessel registration: who qualifies as an owner
Cayman vessel registration follows the British system of 64 shares: the vessel must be majority-owned by a qualified person, a non-qualified party holding at most 31 of the 64 shares. Qualified owners are the citizens and companies of more than 70 approved jurisdictions — listed in section 2.2 of Guidance Note CIGN 03/2024, from the UK, its Overseas Territories and Crown Dependencies to the EU/EEA states — plus foreign companies registered in Cayman with a local establishment, and partnerships from qualifying jurisdictions.
Any owner not resident in the Cayman Islands must also appoint a Representative Person, resident in the islands, to receive official documents — a statutory requirement, not to be confused with the Authorised Person, an optional professional agent who manages the application.
The five steps to register with the CISR
The official procedure runs in five steps:
- Vessel qualification and name availability. The proposed name can be reserved for 12 months, renewable, on each of the three Cayman ports of registry.
- Owner qualification and proof of title — Bill of Sale for an existing vessel, Builder’s Certificate for a new build.
- Representation: the owner acts directly or appoints an Authorised Person.
- Forms and fees: forms CISR 854 to 857, supporting documents and fees per the Registration Matrix. Electronic filing is accepted, with certified originals to follow within 7 days.
- Issuance of the Certificate of British Registry and the Carving & Marking Note, to be returned verified within 21 days — it prescribes how name and port of registry are marked on the hull.
Two practical notes. The radio call sign is allocated by the CISR; the MMSI number comes from OfReg, the Cayman telecoms regulator. And a vessel cannot fly two flags at once: on a re-flagging, the deletion certificate of the outgoing registry drives the calendar far more than the CISR does.
Full, interim or term: choosing the registration type
Since the Merchant Shipping Act (2024 Revision), the MACI nomenclature distinguishes five registration types:
- Full registration — the standard regime: a Certificate of British Registry with no expiry date.
- Interim registration — a 21-day bridge during a transfer of ownership. Bill of Sale and Declaration of Ownership must be filed within those 21 days on pain of deletion; registered mortgages remain on the register.
- Term registration — up to 90 days, one-time, no extension, while the Certificate of Survey is pending: the former provisional registration, pre-2024 vocabulary for the same mechanism.
- Registration under construction and demise (bareboat) charter in/out complete the list.
One trap: the 90-day Term registration is not the 3-Year Term Registration of the 2026 schedule — a package for pleasure yachts under 24 m (USD 2,750 with three years of prepaid tonnage fees; renewal USD 1,500). Same word, two different things.
George Town yacht registration: what the name on the transom means
Searches for Georgetown yacht registration — Georgetown in one word is a common spelling; the official one is George Town — point to a simple fact: George Town (Grand Cayman) is the principal of the three Cayman ports of registry, with The Creek (Cayman Brac) and Bloody Bay (Little Cayman). The port of registry appears beneath the yacht’s name on the transom — hence “George Town” across the stern of most Cayman-flagged superyachts.
The designation is administrative and creates no obligation ever to call there. The registry is headquartered in George Town, works through 19 offices in 15 countries and invoices in USD.
Boat flag registration fees — 2026 CISR schedule
Boat flag registration fees under the Cayman flag are set by notice CISN 04/2026 Rev 1.1, in force since 1 April 2026 (replacing notice 03/2022 Rev 3.0). The main amounts, in USD:
| Item | Fee (USD) |
|---|---|
| Initial registration, transfer or deletion — tender | 700 |
| Initial registration — yacht up to 400 GT | 1,750 |
| Initial registration — yacht from 400 GT | 2,250 |
| Registration of a transfer of ownership | 1,500 |
| Vessel under construction | 700 |
| Name reservation (12 months) | 700 |
| Change of vessel type | 800 |
| Transfer between Cayman ports of registry | 850 |
| Mortgage — registration, discharge or transfer | 1,100 |
| Annual tonnage fee — up to 400 GT | from 600 / year |
| Annual tonnage fee — 401 GT and above | from 800 / year |
The annual tonnage fee is due by 31 January each year, neither prorated nor refundable for yachts. A discount applies if the vessel is registered within 90 days of a name reservation (clause 5.2); out-of-hours processing adds USD 365/hour, over-the-counter processing doubles the fee. The schedule can change without notice, and the merchant grid (CISN 01/2026, USD 3,000 full registration), often wrongly quoted for yachts, does not apply here. For the full budget beyond registry fees — owning company, Representative Person, surveys, management — see the real cost of the Cayman flag.
Survey requirements by size and use
The technical requirements depend on size and use:
- Pleasure yacht under 24 m: no conventional survey regime beyond COLREG and MARPOL applicability; registration requires a Cayman Certificate of Survey and a Tonnage Certificate (tonnage survey under 24 m: USD 570).
- Pleasure yacht of 24 m and above, under 400 GT: exempt from conventional surveys and audits; only an Engine IAPP if any engine exceeds 130 kW, and an ISPP if more than 15 persons are on board.
- Pleasure yacht of 400 GT and above: IOPP, ISPP, IAPP and EIAPP certificates, with NOx Technical Files.
- Yachts in trade (charter) of 24 m and above: survey and certification under the REG Yacht Code (successor to the Large Yacht Code, LY3). The CISR performs the Large Yacht Code certificate surveys itself, six approved classification societies taking the rest by delegation; certificates run five years at most, with inspections within ±3 months of the anniversary date on pain of invalidity; above 500 GT, ISM and ISPS audits are conducted by the registry.
The pleasure-versus-commercial decision thus sizes the survey burden long before any charter income — see pleasure vs commercial registration.
Preparing the file: where the weeks are won
The CISR side is fast — 24 hours on a complete file. The calendar is decided upstream: ownership structure and Representative Person, title chain and KYC, Certificate of Survey and, on a re-flagging, the closing–deletion–registration sequence so the yacht is never left without a flag or valid insurance. That preparation is what our flag & insurance service manages end to end, from name reservation to the Certificate of British Registry.
