A yachting certificate is not earned in the exam room alone. For the UK Maritime and Coastguard Agency (MCA), whose certificates remain the industry benchmark, it is earned first in days: days at sea, days on stand-by, days in the yard, each counted against a precise definition. The document that proves them is the sea service testimonial. When a certificate application fails, it rarely fails on the exam. It fails on this piece of paper.
The organisations that verify testimonials see the same pattern every season: missing dates, overlapping periods, a signature that is absent or not acceptable. Each error sends the file back to the seafarer, sometimes months later, when the signatory has left the yacht and no longer answers.
What the testimonial has to prove
The MCA does not count “time spent on a yacht”. It separates four categories, which must not overlap:
- Actual sea service: days underway, including time at anchor and river or canal transits that form part of a passage. A day counts when the yacht has been underway for at least four hours in twenty-four, main propulsion in use.
- Stand-by service: time in port, fully operational, between voyages. It counts in blocks of no more than 14 consecutive days, and never for longer than the preceding voyage.
- Yard service: build, refit or repair, in or out of the water.
- Yacht service: the total time signed on the yacht, as set out in the employment agreement.
The categories do not carry equal weight. For the Officer of the Watch (OOW) yacht certificate below 3,000 GT, you need 365 days in total, of which at least 250 days of actual sea service. The balance may come from stand-by and yard time, the latter capped at 90 days. The yacht must also measure at least 15 metres load line length. A winter in refit does not replace a season at sea, and the testimonial has to let the verifier check that line by line.
Who signs, who verifies
The testimonial is signed by the master. Depending on the case, the chief officer, chief engineer, owner or manager may also sign. One rule has no exceptions: nobody signs their own testimonial. A master’s sea service must be confirmed by the owner or by the yacht’s management company.
For a Notice of Eligibility or a certificate revalidation, the testimonial then has to be verified by a recognised body, in practice the Professional Yachting Association (PYA) or the Nautilus union. The process is now fully digital: the seafarer completes the online form and sends it to the signatory, who confirms with a digital signature. The file is then reviewed and either approved or returned with questions. Allow up to 25 working days. An application sent to the MCA without this verification is delayed by months.
The mistakes that get a file rejected
Most rejections come down to form, and can be fixed upstream:
- Incomplete dates. A testimonial always carries a start date and an end date, including for crew still on board or on a year-round contract. That period is the reference for the calculation.
- Overlapping periods, between two testimonials or with service already on record.
- A total exceeding the employment period. The service claimed cannot be longer than the contract.
- A rotation cut into pieces. Rotational crew produce one testimonial for their whole time on the vessel, stating how often they were on and off.
- Misapplied definitions. Deck and engine each have their own MCA definitions. Check them before sending the form to your signatory.
- A scattered document. All pages of one testimonial belong in a single, readable PDF.
The most useful rule fits in one sentence: get your sea time verified before you leave the yacht. Captains move on, email addresses change, so do management companies. A testimonial that nobody can sign any more is a lost season.
The manager’s part
For the owner and their ship manager, the testimonial is not paperwork to clear at the end of a contract. It commits the yacht’s signature, and it has to match the other records: the official log, the crew list, employment agreements, hours of rest records. A testimonial claiming 200 sea days when the log shows 150 exposes the signatory as much as the seafarer.
The management company also signs for the master. It therefore needs complete, archived records that do not depend on the memory of whoever has left the vessel. This is part of our crew management and MLC compliance work, alongside the seafarer’s rights under the convention that we set out in MLC 2006: your rights on board.
On the seafarer’s side, keep a copy of every verified testimonial, your contracts and your records. That is what a manager will ask for at your next application, and what you can keep current in the Cursorio crew area rather than rebuilding it before every new engagement.
