The MCA-approved shore-based programme that qualifies post-cadetship deck officers for the Chief Mate (Unlimited) Certificate of Competency under STCW regulation II/2 — the essential step from OOW to senior command.
The Chief Mate (Unlimited) Post Cadetship — Examination Route is a shore-based academic and exam preparation programme that leads to the MCA Chief Mate (Unlimited) Certificate of Competency (CoC) under STCW Convention regulation II/2. The course is approved by the Maritime and Coastguard Agency (MCA) under the modernised seafarer training framework (MIN 720(M)), with the academic component accredited by the Scottish Qualifications Authority (SQA). The underlying international competence standards are set by the International Maritime Organization (IMO) in Table A-II/2 of the STCW Code, and the relevant UK statutory instrument is MSN 1856 (M+F) Amendment 1.
The programme covers passage planning and voyage management at management level, advanced ship stability and structure, bridge resource management, cargo operations, shipboard management, maritime law, marine meteorology, ECDIS at management level, and command and leadership competencies. It also incorporates or bundles the mandatory NAEST(M) (Navigation and Watchkeeping Simulator, Management Level) and HELM(M) (Human Element Leadership and Management, Management Level) short courses. The pathway concludes with SQA written examinations in Navigation and in Stability and Structure, followed by an MCA Oral Examination B, after which the MCA issues the CoC.
Any UK deck officer who has completed a cadetship, holds an OOW (Unlimited) II/1 CoC, and has accumulated at least 12 months of approved watchkeeping sea service must complete this programme in order to serve as Chief Mate on commercial vessels of 500 GT or more in unrestricted trading areas. It applies across all vessel types — cargo ships, tankers, passenger vessels, RoPax, bulk carriers, and large commercial yachts above applicable gross tonnage thresholds. No officer may lawfully serve as Chief Mate on an unlimited vessel without this certificate.
Holding the Chief Mate (Unlimited) CoC authorises service as Chief Mate on any merchant vessel of unlimited gross tonnage anywhere in the world. The concurrent award of Master (<3,000 GT) at the same examination opens the door to command appointments on smaller commercial ships — including large commercial yachts, offshore support vessels, and coastal cargo ships — while accumulating the sea time required for the full Master Unlimited certificate. Officers in possession of the Chief Mate (Unlimited) CoC are sought after across all deep-sea shipping sectors and form the direct management-level pipeline for bridge command.
