Under the Cayman flag, “pleasure” is a mode of use, not a vessel type: the Certificate of British Registry recognises only two designations for a yacht — Pleasure Yacht or Commercial Vessel — and it is the use at the relevant moment that determines the applicable regime (CIGN 04/2023 Rev 01, §3.1-3.2). The practical consequence is immediate: the moment a yacht is engaged in trade, even for a single charter, the full set of commercial requirements applies — the Cayman Islands operate no reduced-requirement charter regime. Here is the complete trade-off under the notices in force in 2026, YET programme included.
Two registry designations, one strict legal definition
The definition of a pleasure vessel sits in section 2 of the Merchant Shipping Act (2021 Revision), reproduced in Annex 1 of CIGN 04/2023: a vessel used only for the sport or pleasure of the owner, their immediate family or friends, on a private basis — carrying no goods or passengers for reward, and not offered to the public. Single tolerance: guests may contribute to the direct costs of the voyage.
The practical reading: the boundary is not the form of the contract but the money — any payment beyond the direct costs of the voyage amounts to engagement in trade.
What switching to commercial actually triggers
Going commercial is not a line item on a certificate. Four blocks of obligations activate:
- Technical code — a yacht of 24 m and above (load line length) engaged in trade must meet the Large Commercial Yacht Code, which covers REG Yacht Code Part A (July 2024 edition, in force since 1 July 2024), under Regulation 4(3) of the Merchant Shipping (Vessels in Commercial Use for Sport or Pleasure) Regulations 2002. Below 24 m: the small commercial vessel codes (CIGN 04/2023, §2.6-2.7 and 4.3-4.4).
- MLC 2006 — mandatory whatever the size: no Certificate of Compliance to engage in trade is issued without confirmation of MLC arrangements (§5.1-5.2).
- Manning — Minimum Safe Manning must be met at all times, with Cayman endorsement of all eligible STCW certificates (§6.2-6.3).
- Certification — Large Commercial Yacht Certificates are valid for a maximum of 5 years, with annual inspections within a ±3-month window; above 500 GT, add SMC (ISM), ISSC, Continuous Synopsis Record and Minimum Safe Manning Document — covered in our ISM and ISPS requirements under the Cayman flag.
The registry backs this framework with criminal sanctions: non-compliant chartering is an offence by the owner and the master, punishable by a CI$50,000 fine on summary conviction, or 2 years’ imprisonment plus CI$50,000 on indictment (CIGN 04/2023, §4.7).
The 12-passenger rule and the Passenger Yacht Code
In commercial use the ceiling is structural: a Large Yacht certified to REG Yacht Code Part A carries up to 12 passengers; from 13 to 36 passengers the yacht falls under Part B — the former Passenger Yacht Code — with no cargo carriage (CIGN 06/2025 §1.3 ; REG Yacht Code Part B). The threshold echoes the SOLAS Convention (regulation I/2), which defines a passenger ship as one carrying more than 12 passengers.
For events at berth or at anchor, a temporary exemption regime has existed since September 2025 under section 159(1) of the Merchant Shipping Act (2024): at berth, no exemption is required (Letter of No Objection on request); at anchor within port limits, a CISR exemption plus port authority agreement; outside port limits, coastal State agreement on top. Life-saving appliances must follow — liferafts for 100% or 125% of persons, lifejackets for 110% — and insurer agreement features among the expected risk-control measures.
Pleasure vs commercial: the comparison table
| Pleasure Yacht | Commercial Vessel | |
|---|---|---|
| Use | Private: owner, family, non-paying guests | Charter and any engagement in trade |
| Technical code | No commercial code required | REG Yacht Code Part A (≥24 m) or small commercial codes (<24 m) |
| Surveys | No statutory survey/audit below 400 GT | 5-year certificates, annual inspections ±3 months |
| MARPOL | IOPP/IAPP above 400 GT, Oil Record Book from 400 GT | Full certification by tonnage |
| MLC 2006 | Out of scope (no commercial activity) | Mandatory whatever the size |
| Manning | Minimum Safe Manning not required at all times | Permanent Minimum Safe Manning, Cayman-endorsed certificates |
| ISM / ISPS | Not required | SMC, ISSC, CSR above 500 GT |
| Passengers | Private guests | 12 max (Part A), 36 max (Part B) |
One clarification on the pleasure column: MARPOL applies to all, but only the IOPP/IAPP certification is reserved for yachts above 400 GT — with the Oil Record Book mandatory from 400 GT, including for strictly private yachts (MACI survey FAQ, consulted August 2026). The full budget differential between the two statuses is quantified in Cayman flag costs.
Can you charter and stay “pleasure”? The YET programme
There is no Cayman equivalent of a Private Yacht Limited Charter Scheme — no regime, as under the Marshall Islands flag, allowing a few weeks of charter against reduced requirements: CIGN 04/2023 (§1.2 and 8.1) rules it out expressly.
What does exist is the YET (Yacht Engaged in Trade) programme, governed since May 2026 by CIGN 06/2026 Rev 1.0 — which replaces Shipping Notice 03/2017, still cited by many outdated sources. The principle: a pleasure yacht of 24 m and above, fully compliant with the REG Yacht Code, may charter up to 84 days per calendar year. During each charter, a temporary YET Certificate of British Registry suspends the “Pleasure Yacht” certificate; the yacht also holds a YET Certificate of Compliance, backed by annual surveys.
The YET is therefore not a derogation: the flag’s role is limited to verifying that the yacht is certified to the same requirements as a permanently registered Commercial Vessel (§2.5), and under Port State Control the yacht should expect to be treated as a commercial yacht under the Paris MoU (§8.1). The initial scope covers French and Monegasque waters, with facilitated extension to jurisdictions adopting the same framework (§2.4 and 4.5). It also ended the former practice of flipping registration between “Commercial” and “Pleasure” around European charters (§2.1-2.2).
On tax, CIGN 06/2026 sets markers: yacht VAT paid or under Temporary Admission (18 months in EU waters, reserved for non-EU beneficial owners and companies), TA clock paused during each YET charter period, private use by the owner prohibited while the temporary certificate is valid, and no VAT exemption on fuel or provisioning. These matters belong to tax counsel and the customs broker, not to the flag State — the registry says so itself.
How to decide
Three questions usually frame the call:
- How many charter days per year? Zero: pure pleasure, the lightest regime below 400 GT. Up to 84 days, mostly in France and Monaco: the YET, provided you accept full commercial certification. Beyond that: Commercial registration is the answer.
- Which cruising area? The YET remains centred on the France–Monaco seaboard; a Balearics, Greece or Caribbean charter programme calls for a different architecture.
- How much administrative appetite? REG Yacht Code, MLC, manning, annual surveys: commercial compliance is a permanent operating commitment, not a formality.
