A merchant navy cadetship is the main route to becoming a deck officer in the UK, and if you are researching a merchant navy cadetship UK-wide, the process comes down to three things: finding a sponsor, choosing a college route, and completing alternating periods at college and at sea. This guide explains how it works and what to do first.
Key points
- A sponsored officer cadetship is typically a fully funded programme of about three years, alternating between college and sea.
- Routes lead to an academic award (HNC/HND, foundation degree or degree) and an MCA certificate of competency as Officer of the Watch.
- Sponsors, not colleges, offer the cadetship place; Careers at Sea lists two intakes a year, September and January, and some colleges also start in April.
- Typical entry is four GCSEs including maths, English and a science, or UCAS points for the degree routes, plus a pass in the ENG1 medical.
What is a cadetship?
A cadetship is a training programme in which you train as a deck or engineering officer while employed or sponsored by a shipping company or similar sponsor. Careers at Sea describes the officer trainee programme as fully funded and lasting about three years, leading to an academic qualification and an MCA certificate of competency. Sponsors usually cover college fees and travel and pay a monthly bursary towards living costs. This article focuses on the deck route, which leads to the OOW certificate, the first rung on the deck officer ladder.
Routes into the Merchant Navy
- Sponsored officer cadetship: the standard route, covered below.
- Pre-cadetship course: if you lack the right qualifications, a college pre-cadetship course of about a year prepares you to apply.
- Apprenticeship: Careers at Sea lists an OOW apprenticeship route for the OOW 500gt (Near Coastal) certificate.
- Rating then officer: some seafarers start as deck ratings and progress, and yacht crew can follow the OOW yachts route. That path is separate from the cadetship.
Sponsorship: how it works
You do not apply to a college for a cadetship; you apply to a sponsor. Sponsors can be shipping or ship management companies, training management companies that place cadets with their clients, or charities. Careers at Sea names examples such as BP, James Fisher, Stena Line, Trinity House and Anglo Eastern. Once a sponsor offers you a place, they place you with a partner college and arrange your sea phases. Applications can be made up to a year before training starts, so you do not need your exam results first. Officer sponsorship is open to UK citizens and EU citizens who have lived in the UK for over 12 months, according to Careers at Sea, so check the current rule with each sponsor.

Entry requirements
| Route | Typical entry |
|---|---|
| HND / advanced diploma | At least four GCSEs at grade 4 to 9 (or equivalent), including maths, English and a science |
| Foundation degree | 48 UCAS points, including maths and/or physics, plus the GCSEs above |
| Degree | 104 UCAS points |
| All routes | A pass in the ENG1 medical (see our ENG1 medical guide) and sponsor approval |
Sponsors set their own criteria, so check each one. Start your ENG1 early, because a problem with vision or health can end an application.
HND, foundation degree and degree routes
Colleges and universities such as Solent University's Warsash Maritime School, South Shields Marine School, Fleetwood Nautical Campus and City of Glasgow College offer deck cadet programmes. The main academic routes are:
- HND in Nautical Science: a diploma that leads to the OOW certificate, with a top-up route to a degree after the HND at some providers.
- Foundation degree (FdSc): the same OOW certificate with an academic award that gives a direct route onto a BSc top-up.
- Bachelor's degree: a degree route that includes the OOW certificate.
All lead to the same MCA certificate of competency. Choose by entry requirements, sponsor, location and whether you want a degree. A new UK-wide officer cadet syllabus (the MCA's modernised syllabus, MIN 720) took effect from September 2025, and it is also replacing the old written examinations with new assessments, so check which applies to your intake.
Sea phases and college phases
Training alternates between college and sea in five phases, beginning and ending with college. Deck cadets need at least 12 months at sea, with voyages often lasting two to three months. At sea you work under a training officer, complete a Training Record Book, and learn watchkeeping, cargo operations, safety, mooring and bridge work, all while preparing for the written exams. Back at college you take the theory and safety courses, including the STCW basic safety training and GMDSS (see GMDSS GOC vs ROC).
OOW Unlimited and beyond
At the end of the programme, you complete the MCA's assessments (written examinations under the old syllabus, modernised assessments under the new one) and the oral for the Officer of the Watch certificate of competency. A cadetship leads to an unlimited-tonnage OOW certificate, which lets you stand a navigational watch on ships of any size, worldwide. The oral is a serious test: read our OOW oral exam guide, and revise COLREGs and ship stability properly. After that, promotion depends on further sea service and exams for chief mate and master.
Is a cadetship right for you?
A cadetship is a good fit if you want a structured route to officer rank, with your training paid for, and you are comfortable with long periods away from home. Time at sea means being away for weeks or months at a time, living in a small community on board, working shifts and keeping watches at night. Many cadets say that is the part that surprises them most. If you are unsure, talk to serving officers, look at Careers at Sea, and consider a short taster or a pre-cadetship course before you commit.
The reward is a recognised international qualification that can lead to work on cargo ships, tankers, ferries, offshore vessels, cruise ships and, later, yachts, where an unlimited certificate counts for a great deal. Many yacht officers began as merchant navy cadets.
How to apply: a plan
- Check you meet the academic requirements, or look at a pre-cadetship course.
- Book your ENG1 with an MCA approved doctor.
- Research sponsors and their deadlines (September and January intakes).
- Apply, ideally to several sponsors, and prepare for interviews and aptitude tests.
- Once accepted, confirm your college and start date.
