Rest-Hour Compliance for Passenger Vessel Operators

This guide shows how ferry, tour boat, and passenger vessel operators can keep rosters, work/rest logs, and corrective actions aligned with STCW Section A-VIII/1, MLC 2006 Standard A2.3, and the Norwegian Ship Safety and Security Act section 24. The key limits are 10h/24h, 77h/168h, and split rest using the 6h/14h structure.

Why passenger vessel rosters quietly break rest-hour records

Passenger operations look predictable: a published timetable, fixed routes, regular crew. In practice, the timetable is fixed but the roster is not. Crew cover for sick colleagues, extra departures are added in high season, and people move between vessels in the same operation.

Most findings on passenger vessels do not start with anyone deciding to ignore the rules. They start with a split shift that quietly exceeds the 14-hour interval, or a crew member whose actual hours no longer match the published roster. If records are compared to the timetable instead of to actual work, deficits stay invisible until an inspection.

Which rules apply to passenger vessels

Passenger vessels and fishing vessels follow different frameworks. Mixing them up is a common documentation mistake, because the rest numbers are similar but the legal references are not.

The core rest limits to build into the roster

The numbers are simple. The hard part is checking them against actual hours while the vessel is running, not days later in the office.

Minimum 10 hours rest in any 24-hour period

This is a rolling-window control, not a midnight-to-midnight box-tick. Any 24-hour window, counted forward from when a crew member starts work or backward from when they finish, must contain at least 10 hours of rest. Checking only by calendar day misses real deficits.

Minimum 77 hours rest in any 168-hour period

The weekly rolling requirement catches cumulative strain. A vessel can look compliant day to day while drifting into weekly risk through repeated small shortfalls. Crew working seven days straight effectively need 11 hours of rest per day to stay compliant.

Split-rest structure: 6h/14h

The daily rest may be split into no more than two periods if one period is at least 6 continuous hours and the interval between consecutive rest periods does not exceed 14 hours. Morning-and-evening split shifts around peak departures are exactly where this interval rule gets tested.

Maximum 14 hours work in any 24-hour period

This follows directly from the 10-hour daily rest minimum. Long turnaround days with an early first departure and a late last arrival need active checking, not assumptions.

Required documentation: daily rest records

STCW A-VIII/1 is explicit about the paperwork. Records of each seafarer's daily hours of rest must be kept in a standardized format, in the working language of the ship and in English, so that compliance can be monitored and verified.

Endorsement

The records must be endorsed by the master, or by a person authorized by the master, and by the seafarer. A logbook nobody has signed is weak evidence.

Personal copies

Each seafarer is entitled to a copy of the records pertaining to them. Digital systems make this trivial; paper systems make it a monthly chore that is often forgotten.

Plans vs. actuals

The roster shows intended work. The rest records show what actually happened. Inspectors compare the two, so when the day changes, the records should show how and why.

A practical routine for passenger vessel operators

A simple routine done consistently beats a large cleanup before inspection.

Step 1: Plan the season, not just the week

Identify the periods where rest risk concentrates: summer peak departures, event traffic, extra evening sailings, and crew vacation cover. Write these into the roster assumptions before the season starts.

Step 2: Check the roster against the limits before publishing

Every planned roster should be verified against 10h/24h, 77h/168h, and the 14-hour interval rule before it goes out. A roster that is non-compliant on paper will be non-compliant on board.

Step 3: Record actual hours the same day

Require same-day entries wherever possible. Late reconstruction introduces memory errors and weakens the file. Short variance notes when the day diverged from plan are worth more than perfect-looking records.

Step 4: Handle exceptions with a decision, not a note

When limits are at risk, document the actual response: who covered, what changed, and when it was decided. A one-line remark after a breach is not a corrective action.

Step 5: Review weekly across vessels

Crew moving between vessels carry their rest history with them. Review rolling 24h and 168h status per person, not per vessel, at least weekly during the season.

Step 6: Test the file like an inspector

Periodically pick one crew member and follow their plan, actuals, deviations, and sign-offs for a month. Use the maritime rest-hour inspection guide as the checklist.

Common failure patterns in passenger operations

"The timetable is compliant, so we are compliant"

The timetable never calls in sick. Crew covering for colleagues changes actual hours, and the records must reflect reality, not the poster at the dock.

Split shifts that drift past 14 hours

A morning block and an evening block can look harmless while the interval between rest periods quietly exceeds 14 hours. This is the single most common hidden breach in scheduled passenger service.

One crew member, two vessels

When a crew member works on two vessels in the same operation, each vessel's log can look fine while the person's combined day breaks the rules. Rest tracking must follow the person.

High-season drift

Extra departures added in July erode weekly rest gradually. The 77h/168h rolling check exists precisely for this drift, and it only works if actual hours are recorded.

Unsigned records

Records that were never endorsed by master and crew carry little weight in an inspection interview. Build sign-off into the monthly routine.

When spreadsheets and paper start to fail

Many passenger operators start with a spreadsheet per vessel. That works until crew move between vessels, split shifts need interval checks, or an inspector asks for six months of endorsed records. A useful digital workflow should:

• Check rolling 10h/24h and 77h/168h limits automatically from actual logged work.
• Flag split-rest interval risk before the shift starts.
• Follow the crew member across vessels and shift swaps.
• Produce signed PDF reports for crew, master, and inspector without manual rebuilding.

The hours of rest calculator is a good way to test scenarios before changing a roster.

Final takeaway

Passenger vessel rest-hour compliance comes down to simple habits done consistently: rosters checked before publication, actual hours recorded the same day, short notes when the day changed, and weekly review per crew member across vessels.

The frameworks are STCW A-VIII/1, MLC 2006, and the Ship Safety and Security Act section 24. Fishing vessels have their own rules under STCW-F and ILO C188 — and their own STCW-F compliance guide.
