Hours of rest and annual leave at sea: what MLC 2006 guarantees

Fatigue is one of the biggest safety risks at sea, so the Maritime Labour Convention sets hard limits on working time and rest. Whether you work on a ship or a commercially operated yacht, these are the numbers you should know.

Key takeaways

  • ✓Minimum rest: 10 hours in any 24-hour period and 77 hours in any 7-day period.
  • ✓Or, as the alternative limit: maximum 14 hours of work in any 24 hours and 72 hours in any 7 days.
  • ✓Rest may be split into no more than two periods, one of them at least 6 hours long.
  • ✓Minimum paid annual leave: 2.5 calendar days for each month of employment.

The two ways a flag state can set the limit

Standard A2.3 of the MLC lets each flag state choose either a maximum number of working hours or a minimum number of rest hours. Either way, the limits below are the floor that cannot be undercut.

MLC 2006, Standard A2.3. The ILO notes that the two regimes are not exactly equal over a week: 72 hours of work leaves 96 hours of rest, more than the 77-hour minimum.

How rest can be split

Drills (muster, fire-fighting, lifeboat) should be held in a way that disturbs rest as little as possible. If you are on call and get called out during rest, you should get compensatory rest.

  • •No more than two rest periods in 24 hours
  • •One of them must be at least 6 hours long
  • •No more than 14 hours between two consecutive rest periods

Records you are entitled to

The vessel must keep records of your daily hours of rest, and you are entitled to a copy endorsed by the master or a person authorised by the master. Keep your copies — they matter in any dispute about fatigue or overtime.

Annual leave

Under Standard A2.4, paid annual leave is at least 2.5 calendar days for each month of employment. Agreements to give up the minimum annual leave in exchange for money are generally not allowed, except in cases set by the competent authority.

Your Seafarer Employment Agreement (SEA) should state your leave entitlement and how it is calculated.

If the rules are broken

  • •Write down your actual hours and keep copies of the official records
  • •Raise it with the master or head of department first
  • •Use the on-board complaint procedure that the MLC requires
  • •Contact the flag state, a port state inspector or your union if it is not resolved

On Maritime Delivery, assignments come with a written agreement and an assignment hub where both sides can see the plan and the voyage log — a clear record helps everyone keep to safe working hours.

Rules change and differ between flag states. Use this guide as a starting point and always confirm current requirements with the issuing body or flag administration before you book a course or accept a job.
