Workboat Code 3: What Qualification Do You Actually Need for Your Area Category?

Why This Matters

Appendix 5 of Workboat Code Edition 3 is where the Code answers a very practical question: what qualification actually lets you be Master of a specific workboat, in a specific Area Category? Vessels complying with the Code are exempt from the standard STCW Watchkeeping Regulations 2022 and the Safe Manning Regulations 1997 — but only if manning follows the tables in this Appendix instead. Get this wrong and the vessel isn't legally manned, regardless of how experienced the crew actually is.

The Deck Manning Table — Area Category Sets the Ceiling

Table A5.1 works on a sliding scale: the further offshore and more demanding the Area Category (6 being the most sheltered, 0 the most exposed/unlimited), the higher the qualification required to hold Master. A few real anchor points from the actual table:

• STCW Master (Workboat <500GT, unlimited area) and STCW Master (Code Vessels <200GT, unlimited area) — valid across every Area Category, 6 through 0.
• RYA/MCA Yachtmaster Ocean — also valid across every category, provided it carries a commercial endorsement (which itself requires a valid Medical Fitness Certificate, a Sea Survival or Personal Survival Techniques course, and the RYA Professional Practices and Responsibilities course).
• MCA Boatmasters' Licence — valid for Categories 6 through 3 only, limited to the area of the licence and its endorsements (MSN 1853(M)).
• RYA/MCA Yachtmaster Coastal — also 6 through 3.
• RYA/MCA Powerboat Level 2 Certificate — Category 6 only, and only on open boats, RIBs, inflatables or buoyant-collar boats under 3GT.
• Day Skipper Theory & Practical — daylight operation only, Categories 6 and 5.

On top of the Master's own qualification, several categories require a second, separately-qualified person aboard — the requirement scales from ‘someone the owner/operator considers experienced and competent’ at the lower categories, up to a named RYA/MCA Yachtmaster Coastal or higher at the top end.

Engineering Manning — Power Threshold Drives the Requirement

Table A5.2 is built around registered propulsion power rather than Area Category alone. A Marine Engine Operators Licence (MEOL) or equivalent covers a ‘Power Vessel W’ (a vessel doing towing, lifting, or carrying cargo over 1000kg) up to a certain threshold; above 1500kW you move to a Senior MEOL or STCW III/2-equivalent qualification, and above 3000kW/9000kW into STCW III/2 Small Vessel Chief Engineer territory. One rule applies regardless of category: at least one crew member must always be sufficiently familiar with the vessel's machinery and maintenance to ensure a safe passage.

Mandatory Training — Not Just the Master's Ticket

Table A5.3 sets out training requirements that apply on top of the manning tables, and several of these catch crew out because they're easy to assume are someone else’s requirement:

• Sea survival: STCW-route operators need MCA-approved Personal Survival Techniques; everyone else needs RYA Basic Sea Survival at minimum.
• First aid: the requirement scales with Area Category and MLC status — from a full Proficiency in Medical Care certificate at Category 0/1 on non-MLC vessels, down to an Elementary First Aid or equivalent at Categories 2–6.
• Firefighting: vessels under 15m need one crew member trained; vessels 15m and over need every crew member trained.
• Radar, stability, and ECDIS training are all separately mandatory wherever the vessel actually carries that equipment — carrying an electronic chart plotter you're not trained on isn't a grey area, it's a Code requirement you're not meeting.

New: Battery Propulsion Training

Appendix 5 was updated to require that any vessel using lithium-ion or lead-acid batteries as a source of propulsion power must have training requirements documented in the vessel's operating manual, covering at minimum: normal operation, maintenance, and how to rectify common faults and issues. If your vessel runs battery-hybrid or battery-electric propulsion, this isn't optional paperwork — it's a distinct, named training obligation alongside everything else in this Appendix.

Check Your Vessel

• Skipper/Owner: Does the Master's actual certificate match a row in Table A5.1 for the vessel's certified Area Category — not just the category it usually operates in?
• All crew: If the vessel carries a chart plotter, radar, or runs battery-hybrid propulsion, can you point to the specific training record covering it?
• Owner/Operator: Is there a documented second-person competency requirement being met, where the table calls for one?
