Work & Rest Hours

Every crew member's day is checked against up to eleven rules, depending on the regime: minimum continuous rest in 24 hours (6 hours under STCW), minimum total rest in 24 hours (10 hours), total rest in any 7 days (77 hours), how the rest is divided, the longest stretch between rest periods (14 hours), maximum work in 24 hours, 72 hours and 7 days, consecutive working days and the rest days owed after them on inland waterways, and night work by seafarers under 18.

The check runs as hours are entered. A breach marks the exact half-hour cell on the grid, and the cell's tooltip names each rule it broke. No more end-of-month surprises: violations surface the moment they occur.

Set each vessel's work and rest rules to one of seven regimes: STCW 2010, the ILO Maritime Labour Convention, OCIMF tanker vetting standards, ILO C188 for fishing vessels, two inland waterway regimes and OPA 90. Each regime defines its own limits for minimum rest, maximum work and how rest is divided, and the regimes on offer follow the vessel: C188 for fishing vessels, the inland regimes for inland crewing and OPA 90 for tankers.

When a flag state, charterer or company policy asks for something else, the custom regime lets you set the limits yourself, from minimum rest in 24 hours and 7 days to maximum work hours and the longest stretch between rest periods.

Print on board the table of shipboard working arrangements that MLC 2006 and STCW ask every ship to post where the crew can see it. Navatom builds it from your work templates: each position's schedule at sea, in port and at anchor, its work periods, and its daily totals of work and rest.

The table states the limits that apply on board, the minimum rest in any 24 hours and any 7 days and the longest stretch between rest periods, and carries the name of the master or authorized person, ready to post. Port State Control has its own deficiency code for shipboard working arrangements, so this is a document inspectors check.

View crew work and rest records in three complementary formats: a multi-crew daily view showing all crew members' 48-cell grids for a single day, a single-crew daily view for detailed individual analysis, and a single-crew monthly view providing the full calendar picture required by STCW record-keeping regulations.

The multi-crew daily view is the primary operational tool: the officer responsible for hours-of-rest records sees the entire crew's day at once, spots gaps and catches breaches as the hours go in. The monthly view gathers the month for signing and inspection, and in the single-crew views, public holidays of the vessel's flag state are highlighted.

Create named schedule templates that define standard work and rest patterns for common watch rotations and duty schedules. Templates are defined per ship and can be reused across days, weeks, and crew members — eliminating the need to manually fill 48 cells for every person every day.

Templates are grouped by ship mode, so the sea watch, the port rotation and the anchor watch each have their own. Select the crew on the day's grid, apply a template to all of them in one action, then adjust individual cells as needed for deviations from the standard pattern.

Track special work operations — port calls, emergency responses, cargo operations, bunkering, and other non-routine activities — as distinct operation blocks with their own time boundaries. Operations provide context for why crew members were working outside normal patterns, giving inspectors and auditors the full picture.

Each operation records its type, start and end times, and the crew members involved. Operations integrate with the daily time grid, overlaying special work blocks on the standard schedule.

Operations print with each day on the seafarer's monthly record, so the reason for a long day travels with the hours.

Print a monthly work summary for each vessel: every crew member's rank, hours worked, hours worked in breach of the rules and the breach as a share of the hours, with watchkeepers and the rest of the crew in separate columns and totals for each group.

Print functionality produces formatted reports suitable for office review, flag state submission, and company record-keeping, and shows at a glance where the long hours and the breaches fall.

Designate crew members as watchkeepers on a per-month basis, tracking which personnel stand navigational and engineering watches. STCW sets its hours of rest for the officers and ratings who keep a watch, so it matters to see their hours apart.

The same rest checks run for every crew member, and the monthly work summary reports watchkeepers and the rest of the crew in separate columns: hours worked, hours worked in breach and the breach share, with totals for each group.

Add per-date, per-crew remarks to document the context behind unusual work patterns, schedule deviations, or operational circumstances. Remarks include a description field that captures the officer's narrative explanation — essential for justifying non-standard hours during inspections.

Remarks print with the day on the seafarer's monthly record, alongside the time grid data. During a Port State Control inspection, the inspector can see not only what hours were worked but why.

This contextual layer transforms raw schedule data into a complete, defensible record of crew working time.

Assign distinct colors from a predefined palette to operation templates for instant visual identification on the time grid. An operation's half-hours take its color, with its short name in each cell, so crew and managers can tell a cargo watch from a drill at a glance.

The use-work-color option shows an operation in the normal work color when it needs no color of its own. Operation templates carry Active or Inactive status, keeping your color-coded library organized.

The visual system transforms the daily time grid from a monochrome spreadsheet into an intuitive, scannable schedule.

Where a vessel's flag allows the STCW Manila exception, set it for that vessel and Navatom accepts rest taken in three periods instead of two, counting the two shorter periods only when each lasts at least an hour. It can be allowed under STCW 2010, ILO, OPA 90 and custom rules.

Tankers can run under OPA 90, which adds US limits on work: no more than 15 hours in any 24 hours and 36 hours in any 72 hours. Its non-conformity lines note that the figures include any emergency or drill hours, which OPA 90 leaves out, so the report reads correctly in an inspection.

Work patterns change with the vessel's status, so work templates are kept under three operational modes: Sea, Port and Anchorage. The sea watch, the port rotation and the anchor watch each sit in their own group, ready to apply to the day's crew.

The same three modes structure the printed table of shipboard working arrangements, which shows each position's schedule at sea, in port and at anchor.

A rest-hour violations widget lists each vessel's non-compliant crew days over the last 30 days, how many crew had violations and who was affected most, and on vessels in polar waters, how many deck watch officers hold polar certificates.

The rest hours and non-conformity trend pages show vessels, crew and breach days across the fleet, which vessels and ranks breach most, and whether the breaches are daily, weekly or in how rest is split, with a drill-down to each crew member's days.
