Question 1

What practical crew welfare matters does MLC 2006 govern aboard a large commercial yacht, beyond simply "decent conditions" in the abstract?

Accepted Answer

Minimum rest hours, food and catering standards, accommodation standards, access to onboard/shore medical care, repatriation rights, and a proper complaint procedure crew can use without fear of reprisal MLC 2006 is sometimes called the "seafarers' bill of rights" for exactly this reason — it codifies the practical, day-to-day conditions (rest, food, accommodation, medical access, repatriation, and a safe complaint channel) that determine whether a crew member's working life aboard is genuinely decent, not just whether the vessel looks compliant on paper.

Question 2

At what tonnage threshold does the full ISM Code (not just the lighter safety management provisions within the REG Yacht Code itself) become mandatory for a commercial yacht?

Accepted Answer

500GT — above this threshold a commercially registered yacht on international voyages must comply with the full ISM Code, requiring a Document of Compliance (DOC) for the management company and a Safety Management Certificate (SMC) for the vessel This is a hard regulatory line, not a judgement call — a 499GT yacht and a 501GT yacht sit in genuinely different compliance regimes. Below 500GT (and 24m+), the yacht-specific REG Yacht Code safety management provisions apply; at and above 500GT, the vessel steps up into the full SOLAS-derived ISM Code framework with its DOC/SMC audit and certification structure.

Question 3

What is the practical difference for a Master/Chief Officer between operating under the REG Yacht Code's own safety management provisions versus operating under a full ISM DOC/SMC once a yacht crosses 500GT?

Accepted Answer

Full ISM brings external audit cycles (internal audits, external Flag State/RO audits, non-conformity tracking and close-out), a formally documented Safety Management System with defined procedures across all departments, and a shore-based Designated Person Ashore (DPA) the Master must have direct access to at any time Full ISM is a meaningfully heavier compliance regime — formal audit cycles, documented procedures across every department (not just bridge/deck), and a mandatory DPA relationship are all new obligations a yacht crossing 500GT takes on, distinct from the more streamlined safety management approach below that threshold.
