Yacht crew qualifications follow a clear ladder: a few essential certificates to get your first job, then a structured route through Officer of the Watch (OOW) to Chief Mate and Master. This guide maps the deck (exterior) career from first day to command, in the order you will actually need each ticket.
Key points
- Every deck crew member starts with STCW Basic Safety Training and a valid ENG1 medical.
- An RYA Powerboat Level 2 is the most useful extra for a deckhand, because tender driving is a daily job.
- OOW (Yachts) is the first officer certificate and the biggest single step in the deck career.
- Chief Mate (Yachts) sits on top of OOW with a Yachtmaster Ocean and extra courses; Master (Yachts) adds watchkeeping sea time, five written modules and another oral.
- Exact requirements are set out in MCA guidance (MSN 1858, Amendment 2, May 2026) and change, so always check the current rules.
Yacht crew qualifications: the two you need first
Before most yachts will employ you, two certificates are effectively non-negotiable, whichever department you join:
- STCW Basic Safety Training. The four mandatory safety modules (personal survival techniques, fire prevention and fire fighting, elementary first aid, and personal safety and social responsibilities) plus Security Awareness. The MCA's yacht guidance lists these, with the ENG1, as what you must hold before joining your first vessel on a yacht of 24 metres or over. The course usually runs over about five days, and the survival and fire-fighting modules must be updated every five years.
- ENG1 medical. A fitness-for-sea medical from an MCA-approved doctor. It is a straightforward check of 30 to 45 minutes, the MCA-set fee is £115 (extra tests can cost more), and it is valid for up to two years. Colour vision matters: you are tested for colour blindness because you must be able to identify red and green navigation lights, and a colour vision problem can restrict the roles you can do.
With those two in hand you can start looking for work. For the full beginner route, see our guide on how to become a superyacht deckhand.
The yacht deck ladder at a glance
- Deckhand: STCW basic safety training, Security Awareness and an ENG1 medical.
- OOW (Yachts) <3000GT: 36 months on board including 365 days at sea on yachts of 15m or over, a Yachtmaster, two written exams, ancillary courses and the MCA oral.
- Chief Mate (Yachts) <3000GT: no extra sea time or exams; add Yachtmaster Ocean and the management-level courses (Advanced Fire Fighting, Medical First Aid, HELM Management).
- Master (Yachts): sea service as OOW (12 months for <500GT, 24 months for <3000GT), the Master written modules and the MCA oral.

The deck career ladder at a glance
| Stage | Typical role | What you need (in outline) |
|---|---|---|
| 1 | Deckhand | STCW Basic Safety Training, ENG1, usually RYA Powerboat Level 2 |
| 2 | Officer of the Watch (Yachts <3000GT) | Qualifying sea service, RYA Yachtmaster, written exams, ancillary courses, oral exam |
| 3 | Chief Mate (Yachts) | OOW certificate plus RYA Yachtmaster Ocean and further safety courses (no extra sea time, written modules or oral) |
| 4 | Master (Yachts) | Watchkeeping sea service as an OOW, five written modules and the Master oral |
Stage 1: Deckhand (entry level)
The deckhand is the entry point on the exterior team. You will be washing down, detailing, handling lines, driving tenders and looking after watersports gear. Beyond STCW and ENG1, an RYA Powerboat Level 2 is the most useful add-on. From here the goal is simple: log sea time, learn fast, and start building towards your first certificate of competency.
Stage 2: Officer of the Watch (OOW Yachts <3000GT)
This is the first officer-level ticket and the biggest single step in a deck career. To earn the MCA OOW (Yachts) less than 3000GT certificate of competency you need qualifying sea service, an RYA Yachtmaster qualification, two written exam modules, a set of ancillary safety courses and a final oral exam. The sea service minimum is 36 months of onboard yacht service, including at least 365 days of seagoing service on vessels of 15 metres or over, plus a completed MCA Training Record Book (you are excused the book only if you can show 36 months of actual seagoing service on vessels of 24 metres or over). You must also be at least 19.
The written modules, covering General Ship Knowledge and Navigation and Radar, plus thorough COLREGs and oral preparation, are where most candidates spend their study time. We cover the whole route in how to become an OOW on yachts.
OOW (Yachts) <3000GT: what you are examined on
| Exam | Covers |
|---|---|
| General Ship Knowledge (written) | Construction, stability, anchors and cables, emergencies |
| Navigation & Radar (written) | Chartwork, passage planning, tides, radar and ARPA |
| MCA oral exam | Watchkeeping, COLREGs, lights, shapes and sound signals, emergencies |
COLREGs are not a separate written paper: they are tested hard at the oral, so learn them word for word.

Stage 3: Chief Mate and Master (Yachts)
Chief Mate (Yachts) less than 3000GT is the easiest step on paper: you need your OOW certificate (or to have met all its requirements), an RYA Yachtmaster Ocean with the shorebased course, extra courses (Advanced Fire Fighting, Medical First Aid, HELM at management level) and a valid ENG1. There is no extra sea time, no new written module and no oral, and you can apply for it at the same time as OOW.
Master (Yachts) is where the real work is. Master less than 500GT needs 12 months as a deck officer, including 120 days of watchkeeping, while serving as an OOW; Master less than 3000GT needs 24 months, including 240 days of watchkeeping, with at least 12 months on vessels of 24 metres or over (or six months on 500GT or more). Both need the IAMI written modules in Seamanship and Meteorology, Stability, Business and Law, and Navigation, Radar and ARPA Simulator, plus the MCA Celestial Navigation exam, Medical Care, and a Master oral. Module passes are valid for three years (one year for Celestial Navigation). Yachts of 3000GT and above need an unlimited (unrestricted) certificate, and the May 2026 amendment to MSN 1858 added a yacht-sector route to Chief Mate and Master Unlimited.
These are the tickets that put you in command. The Yacht Fastlane courses let you revise the theory between watches.
How long do yacht crew qualifications take?
There is no fixed timetable. It depends on how quickly you accumulate qualifying sea service and pass your exams. As a rough shape: a few weeks to get job-ready as a deckhand, then at least three years of onboard yacht service (36 months is the MCA minimum) before the OOW oral is realistic, and one to two more years of watchkeeping on top to reach Master 500GT or 3000GT. The crew who move fastest study consistently while they are still on board, rather than waiting for shore-based courses.
Qualification requirements are set out in MCA Merchant Shipping Notice MSN 1858 (Amendment 2, in force from 18 May 2026) and change periodically. Always confirm the current rules with the MCA and your training provider before committing time or money.
Frequently asked questions
What qualifications do I need to work on a superyacht?
At a minimum you need STCW Basic Safety Training and a valid ENG1 medical certificate. An RYA Powerboat Level 2 is strongly recommended for deck roles. Officer positions then require a certificate of competency such as the MCA OOW (Yachts) less than 3000GT.
How long does it take to become a yacht Officer of the Watch?
The MCA minimum is 36 months of onboard yacht service, including 365 days at sea on vessels of 15 metres or over, so three years is the floor. Add the written modules, ancillary courses and a final oral exam, and most crew take three to four years from their first job to the OOW certificate.
What is the highest yacht deck qualification?
Master (Yachts) less than 3000GT is the highest yacht-restricted deck certificate, reached after OOW with additional watchkeeping sea time, written modules and a Master oral. The tonnage limit on your certificate decides how large a yacht you can command; to command a yacht of 3000GT or more you need an unlimited Master certificate.
Do I need sailing experience to start?
No. Many crew join with no maritime background. Practical experience helps, but employers mainly look for a strong work ethic, the right attitude and your STCW and ENG1 in hand.
Do I need STCW and ENG1 before I look for a yacht job?
Yes. The MCA's yacht guidance lists a valid ENG1, the four STCW basic safety modules and Security Awareness as what you must hold before joining your first vessel. It is sensible to pass the ENG1 first, so you know you are medically fit before paying for training.
