Ready before the alarm.

Crew see their muster station and duties on their own phone. Rest hours are checked against MLC 2006 in the same app.

A drill running on the iPad: twenty-one of thirty-one accounted for and ten still missing, the crew grouped by department, and each one marked present or missing as they arrive.

Station, role and equipment, the same for every drill.

Station, role and equipment per crew member, per emergency type. Change it in the admin and the next drill uses it, without reprinting anything.

Each crew member sees their own station and duties on their phone, with the alarm signal for each emergency. Nobody has to find the board in the passageway.

The drill starts from the crew board, not last month’s crew list, and ends with a PDF report of who was accounted for and how long it took.

Master, Chief Officer, Chief Engineer, the ship’s doctor and the Coast Guard, with numbers and radio channels. Fire, DPA and Medical are one press from the muster header, dialled over the vessel’s internet.

Core

Hours of rest, checked against MLC 2006.

Crew log rest on their own phones and every day is checked automatically. Every logged day comes back rested, borderline or non-conformity.

Plus
The admin hours of rest grid for July, a row per crew member with a coloured square per day showing rested, borderline and non-conformity states.
Admin · hours of rest, a month of crew at a glance

10 hours in any 24

Checked against every 24-hour window the day’s work opens or completes, not just the midnight-to-midnight day.

77 hours in any 7 days

A rolling week, looking back from each day’s work. Every rest period counts toward this one.

The two-period rule

Rest may be taken in more than two periods. Only the two longest count toward the 10 hours, so a third rest is not a breach in itself.

Cross an MLC limit and the rule is named on the spot, then the crew member, their HoD and the Captain settle it in one thread.

The rules themselves are set out in the rest-hours guides, and you can check a day on the rest hours calculator.

Coming from desktop rest-hours software? How it compares. Or from WorkRest.

Muster Mate needs no connection.

Rest hours are computed on the phone itself, so a crew member logs the day and sees the verdict with no connection at all. A non-compliant day cannot be saved until a comment explains it.
