How do you join the merchant navy in the United Kingdom?

In the UK, most people enter the merchant navy through a sponsored officer cadetship that alternates college study with sea phases, leading to MCA certification.

Expert Answer

In the United Kingdom the standard route into the merchant navy as an officer is a sponsored cadetship, where a shipping company, often working through the government backed Support for Maritime Training, or SMarT, funding scheme that subsidizes officer cadet training costs, funds and arranges the training in exchange for the cadet committing to the program and often to the sponsoring company afterward. A prospective cadet applies to a sponsoring shipping company or directly to a maritime training provider, and once accepted follows a structured program, typically lasting around three years, that alternates phases of academic study at a nautical college, such as those at Warsash, South Tyneside or Fleetwood among others, with sea phases spent aboard the sponsor's ships gaining approved sea service.

Cadets choose a department at the outset: the deck route leads toward Officer of the Watch and ultimately Master, the engineering route leads toward a watchkeeping and eventually chief engineer qualification, and an electro technical officer route is also available for those focused on electrical, electronic and control systems, reflecting how much modern ships depend on those systems. The academic component is usually studied toward a foundation degree, a higher national diploma or a similar recognized qualification, combined throughout with the mandatory STCW short courses, including basic safety training, and a structured training record book completed and signed off during the sea phases.

On successfully completing the academic work, the required sea service and the training record book, the cadet is examined, including an oral examination, and certificated by the Maritime and Coastguard Agency, the UK's maritime administration, gaining the Officer of the Watch Certificate of Competency that qualifies them to serve as a junior watchkeeping officer, deck or engineering depending on the route chosen. Because most cadetships are sponsored, cadets are typically paid a training allowance or bursary throughout and do not personally cover the course fees, which makes it a genuinely earn while you learn path compared with many other professional training routes, though the terms, allowance level and any tie in commitment vary by sponsoring company and are worth comparing before accepting an offer.

Before starting, and again periodically throughout the career, applicants must pass the ENG1 seafarer medical examination, a UK specific fitness standard covering general health, hearing and eyesight including colour vision, since certain colour vision deficiencies can restrict which roles, particularly navigation, a candidate can be certified for. Ratings, rather than officers, can also enter through separate NVQ based training routes, and experienced ratings can subsequently progress into officer training, so the cadetship is the standard officer route but not the only door into a UK merchant navy career.
