Glossary Term

MLC

MLC stands for Maritime Labour Convention, a global agreement developed by the International Labour Organization (ILO). It’s often described as the "seafarers' bill of rights." Its purpose is to ensure fair and safe working conditions for people working at sea including those on commercial yachts.

Before MLC, maritime labour rules were scattered across dozens of conventions. The MLC, first adopted in 2006, brings everything together under one unified standard.

It helps ensure that:

  • Seafarers work in safe conditions

  • Their wages are paid fairly and on time

  • Living quarters, food, and medical care meet minimum standards

  • They have access to rest, repatriation, and legal support


Does the MLC Apply to Yachts?

Yes, but primarily to commercial yachts:

  • Private yachts not engaged in trade are generally exempt

  • Commercial yachts, including charter vessels and support craft, must comply if flagged under a country that has ratified the MLC

  • Crew employment contracts (SEAs), insurance, and accommodation are all inspected under MLC guidelines

If a yacht is operating commercially under a flag like Cayman Islands, Malta, or Marshall Islands, MLC compliance is almost always required.


What Does the MLC Cover?

Some of the core areas regulated by MLC include:

  • Employment agreements (written, signed contracts for all crew)

  • Work and rest hours (limits on working time, required rest)

  • Medical care (onboard and ashore access)

  • Crew accommodation standards (lighting, ventilation, privacy)

  • Food and catering quality

  • Crew complaint procedures

It also requires vessels to carry:

  • A Declaration of Maritime Labour Compliance (DMLC)

  • A Maritime Labour Certificate (after successful inspection)


Why the MLC Matters for Owners and Managers

  • Avoids port state control detentions or fines during inspections

  • Builds a reputation for responsible yacht management

  • Enhances crew retention, morale, and performance

  • Reduces legal risk in case of disputes or accidents

  • Aligns with ISM Code and safety culture on board


The Maritime Labour Convention (MLC) is not just a legal requirement it’s a foundation for fair treatment and professional standards at sea. For commercial yachts, compliance isn’t optional. But even private vessels can benefit by voluntarily adopting MLC principles to protect crew wellbeing and operational integrity.

MLC covers practical areas like Seafarer Employment Agreements (SEA), hours of work/rest requirements set by the flag, onboard living conditions, catering standards, and access to medical care and repatriation.

Does MLC apply to yachts?

MLC applies mainly to commercially operated yachts under flags that enforce the convention. Many purely private yachts may be exempt, but some owners adopt MLC standards voluntarily to meet insurer/management expectations.

What is MLC compliance on a yacht?

MLC compliance means you can demonstrate, with evidence and records, that crew welfare requirements are met—especially contracts, accommodation standards, medical/repatriation arrangements, and a working complaints process.

What is a Maritime Labour Certificate?

It’s an official document issued after inspection showing the yacht meets MLC requirements (typically required for certain commercial profiles depending on flag and vessel size).

What is a DMLC (Declaration of Maritime Labour Compliance)?

A DMLC is the document that lists how the yacht complies with MLC and what onboard measures/records are used to prove it during inspections.

How often are MLC inspections carried out?

Inspection timing depends on the flag and certificate regime, but it’s typically a cycle with an intermediate check and additional inspections if deficiencies or complaints arise.

What happens if a yacht fails an MLC inspection?

You may face deficiencies, operational delays, reputational damage, and in serious cases detention by Port State Control, especially for commercial yachts.

Who created the MLC?

The International Labour Organization (ILO) a United Nations agency created the MLC to unify and modernize maritime labour standards worldwide.

Does the MLC apply to private yachts?

Not usually. The MLC mainly applies to commercial yachts, especially those flagged under countries that have ratified the convention. However, some private owners choose to follow MLC standards voluntarily to ensure better crew welfare and professionalism.

What does the MLC require from yacht owners?

If your yacht is MLC-compliant, you must provide:

  • Signed employment agreements for all crew

  • Proper work and rest hour logs

  • Adequate medical care, repatriation rights, and insurance

  • Clean, safe accommodation and catering standards

  • Access to a complaints procedure without fear of retaliation

What documents are required for MLC compliance?

  • Seafarer Employment Agreements (SEAs)

  • A Declaration of Maritime Labour Compliance (DMLC)

  • A Maritime Labour Certificate, issued after inspection

These documents prove that your vessel meets the MLC’s minimum standards.

How often are MLC inspections carried out?

Typically:

  • Every five years, with an interim check at 2.5 years

  • Additional inspections may occur if port authorities receive complaints or notice deficiencies during a visit

What happens if a yacht fails an MLC inspection?

Consequences can include:

  • Detention by port state control

  • Fines or loss of commercial status

  • Reputational damage in the charter or crew recruitment market

It’s essential to maintain compliance throughout the year, not just before surveys.

Why is the MLC important for crew?

It guarantees:

  • Fair pay and prompt wage payments

  • Safe working conditions

  • Reasonable hours and adequate rest

  • Medical care and support in emergencies

  • Legal protection in case of conflict or mistreatment

Can MLC compliance help with crew retention?

Yes. Yachts that follow MLC principles, even voluntarily tend to attract and retain higher-quality crew. Professionalism, welfare, and respect go a long way in keeping crew motivated and loyal.
