What the Yacht Rating certificate is

The Yacht Rating certificate sits between green deckhand and the officer track on the deck career ladder. It is the point where properly recorded sea service starts paying off: it certifies you as a trained rating able to form part of a navigational watch on commercial yachts. Unlike the officer Certificates of Competency, which are issued under STCW Regulations II/1 and II/2, the Yacht Rating certificate is applied for on form MSF 4340 under the MCA's own guidance.

Exact requirements

  1. Sea service: at least 6 months onboard yacht service, which must include at least 2 months of actual seagoing service. Qualifying vessels must be at least 15 metres in load line length.
  2. STCW basic training: the four STCW basic courses (A-VI/1-1 to A-VI/1-4), delivered together as STCW Basic Safety Training.
  3. Medical: a valid ENG1 seafarer medical or accepted equivalent.
  4. Training record book: completed tasks as set out in Annex B of MSN 1862.
  5. Service evidence: seagoing service is evidenced using the Yacht Rating and Deck Hand seagoing service testimonial at Annex A of MSN 1858 (M+F) Amendment 2.
  6. Application: apply on form MSF 4340. For fees and processing times, check the current guidance on gov.uk.
