A surveyor reviewing crew welfare facilities on a 280GT yacht notes the crew mess is smaller than a literal reading of MLC 2006's recreational facility guidance might suggest. Explain how this is assessed under the Code's equivalence framework, and what is NOT an acceptable justification for a shortfall.

A. CREW MESS/RECREATION FACILITIES — EQUIVALENCE ASSESSMENT: Under the sliding-scale equivalence framework applied to yachts under 500GT (the same mechanism covering cabin dimensions also extends to other accommodation/welfare provisions), a smaller crew mess/recreation space than a literal merchant-ship-oriented MLC figure may still be compliant if it meets the specific equivalence percentage applicable to that vessel's GT band, as assessed and accepted by the flag state/class at build or refit. WHAT IS NOT AN ACCEPTABLE JUSTIFICATION: (1) "The owner wanted the space for something else" is not, on its own, a basis for a welfare facility shortfall — any reduction must be within the documented, flag-state-accepted equivalence framework, not an ad-hoc trade-off made informally during build/refit; (2) A shortfall that was never actually assessed/accepted under the equivalence framework (i.e. just informally accepted as "good enough") is a genuine compliance gap, not a legitimate equivalence outcome, even if it superficially resembles one; (3) Crew welfare facility provision should not be treated as the most flexible/negotiable line item in a build or refit budget purely because it doesn't affect saleable guest space — that reasoning has no basis in the actual regulatory framework. KEY DISTINCTION FOR THE SURVEYOR/MASTER: smaller-than-merchant-ship facilities can be legitimate (if within the accepted equivalence framework) or a genuine gap (if not) — telling the two apart requires checking the vessel's actual approved documentation, not assuming either outcome by default.

B. Any crew mess size is acceptable on a yacht regardless of GT band, since MLC welfare facility standards do not apply to yachts at all under the Code.

C. A smaller crew mess is always non-compliant regardless of GT band, since the equivalence framework applies only to cabin dimensions and not to other welfare facilities.

D. Reduced crew welfare facility space is acceptable whenever the owner has prioritised guest space instead, regardless of whether this was formally assessed under the equivalence framework.

A. MLC 2006 "SUBSTANTIAL EQUIVALENCE" FOR YACHT ACCOMMODATION — WHY IT EXISTS: When MLC 2006 came into force, its accommodation standards (cabin floor area, headroom, sanitary space etc.) were developed primarily with conventional merchant ship layouts in mind. Applying those standards literally to a yacht's hull form and internal layout — which prioritises guest space differently and has a fundamentally different design envelope, especially below 500GT — would have been impractical or impossible for many existing and planned yacht designs. INDUSTRY RESPONSE: the MCA worked with industry bodies (MYBA, Nautilus International, the Superyacht Builders Association, and flag states) to develop standards of SUBSTANTIAL EQUIVALENCE to MLC 2006's crew accommodation Code, introduced into LY3 from when it came into force (20 August 2013) and carried forward into the REG Yacht Code. SLIDING SCALE: this equivalence is applied on a sliding scale by tonnage — a documented industry approach moves from around 70% compliance with MLC dimensional standards at the 200GT threshold, rising to around 90% just under 500GT, with FULL (100%) MLC compliance required at and above 500GT. WHY THIS MATTERS TO THE CREW MEMBER: a cabin that looks smaller than a literal MLC figure is not automatically non-compliant — it may be correctly built to the vessel's applicable equivalence percentage for its GT band, which is a real, documented, and legitimate regulatory pathway, not an excuse for skipping the standard.

B. MLC 2006 does not apply to yachts at all, so any crew accommodation standard the owner chooses is acceptable regardless of vessel tonnage.

C. The sliding-scale equivalence approach applies equally to all yachts regardless of tonnage, so a 200GT yacht and a 600GT yacht have identical crew accommodation compliance requirements.

D. Equivalence standards are an unofficial industry custom with no basis in the Code itself, and crew accommodation on yachts is entirely unregulated.

A. SEAFARER EMPLOYMENT AGREEMENT — WHY A VERBAL ARRANGEMENT IS NOT SUFFICIENT: MLC 2006 (as applied to coded yachts via the same equivalence framework that governs crew accommodation) requires every seafarer to have a written Seafarer Employment Agreement (SEA) before, or at the point of, joining the vessel, signed by both the seafarer and the shipowner/their representative, setting out terms including pay, leave, repatriation rights, notice periods and duties. A VERBAL ARRANGEMENT IS A COMPLIANCE GAP BECAUSE: (1) The crew member has no enforceable documented record of their agreed terms if a dispute arises (pay, hours, repatriation); (2) Port State Control inspections specifically check for valid, signed SEAs as a routine MLC compliance item — a missing or informally-handled SEA is a detainable deficiency; (3) The vessel's "evidence of financial security" obligations (for repatriation, abandonment, unpaid wages) are tied to the SEA framework — without a proper SEA the underlying financial security protections may not clearly apply to that crew member; (4) The Master/managing company bears responsibility for ensuring SEAs are in place for every crew member on board, not just senior officers — this affects ratings and junior crew exactly as much as licensed officers. ACTION REQUIRED: ensure no crew member works beyond a short administrative grace period without a properly signed SEA, and escalate to vessel management immediately if the issue is more than a one-off oversight.

B. A verbal agreement on pay and role is sufficient under MLC 2006 as long as the crew member is satisfied with the arrangement and raises no objection.

C. SEAs are only required for officers holding a Certificate of Competency; ratings and junior crew may be employed without a written agreement.

D. SEA requirements apply only to crew on vessels over 500GT; smaller coded yachts are exempt from the SEA requirement entirely.
