The regulator wants you to run drills monthly. Your insurer wants the same. Your DPA expects them. But meeting the minimum is not the same as having a crew that's actually ready when something goes wrong. The difference between a drill that satisfies the inspector and a drill that saves lives is mostly in how it's run, not whether it's run.
This article collects what we've heard from real captains, chief officers and safety officers running drills on yachts in production. None of it is groundbreaking. Most of it is obvious in hindsight. But assembled in one place, it's the difference between drills that build muscle memory and drills that just tick a box.
Vary the scenario
If every fire drill you run is "fire in the engine room" and every abandon ship drill is "alongside in fair weather", your crew get really good at exactly two things and have no idea how to handle anything else.
Cycle through scenarios. Run a galley fire one month and a cabin fire the next. Run an abandon ship from anchor, then from underway, then from alongside. Run a man overboard at night with restricted visibility. The point isn't to confuse the crew — it's to expose them to enough variation that the muscle memory transfers when reality looks different from the rehearsal.
The Muster App makes this easy because each scenario is just a tap on the iPad. Build five fire scenarios in the admin panel — engine room, galley, cabin, deck, electrical — and rotate between them month to month.
Vary the time of day
Drills at 1000 on a Tuesday with everyone fresh, fed and expecting it tell you almost nothing. Crew at that hour are at peak performance. The real question is what happens at 0300 when half the crew is off-watch and the rest are mid-passage.
Run drills at the awkward times. Just before dinner. After a long charter day. In the middle of the night. The first few times will be ugly — that's the point. Ugliness in a drill is information. Ugliness in a real emergency is bodies.
Vary the location of the controller
Every drill where the captain is on the bridge running Muster Control is a drill that doesn't test what happens if the captain is the casualty. Try drills where the chief officer runs Muster Control. Try drills where the captain is "missing" and the senior officer present has to take command.
This sounds like role-play but it's the most undertaught skill in maritime emergency response — chain of command under stress when the obvious leader isn't available. Your crew need to know what to do without the captain, because in a real fire on the bridge that scenario stops being hypothetical very fast.
Test the unexpected
The drill scenarios in The Muster App configure the standard cases. Real emergencies have ugly edge cases. Build a few drills around the ugly cases:
- One iPad has been smashed — pretend the bridge iPad is destroyed at the start of the drill. Can the crew still muster using just the iPad in the crew mess?
- WiFi is down — turn off the router for 20 minutes and run a drill on the offline-only iPad. Make sure the cached safety documents you need are actually cached.
- The DPA is unreachable — try to use the DPA VoIP button. If it doesn't connect, do you know your secondary contact? Is the secondary number written down somewhere accessible?
- One crew member is "injured" and can't muster — practice the head count when one person is genuinely unaccounted for. Do you actually go looking for them, or do you assume?
- The fire is between you and your muster station — reroute everyone to a secondary muster point. Does anyone know where the secondary muster point is?
None of this is required by SOLAS. All of it makes the difference between a competent crew and a compliant crew.
Use the audio recording for debriefs
The single highest-value habit you can build with Muster Control is the post-drill audio debrief. After the drill ends:
- Get the senior officers in the bridge or wardroom
- Open the session in the admin panel on a laptop
- Play the first ten minutes of the audio
- Stop and discuss what was clear, what was confused, what was missed
The audio doesn't lie. The captain might remember the drill as "smooth and well-controlled" — and the audio reveals that nobody actually heard the first instruction because it was muffled, or that the chief engineer sounded panicked, or that the bridge was too noisy to communicate. That's all data you can act on.
Most yachts find this is the most useful 20 minutes of their entire monthly safety routine.
Debrief with the crew, not at them
Post-drill debriefs that consist of the captain telling the crew everything they did wrong are worse than no debrief at all. They train the crew to dread drills, hide mistakes, and disengage.
Better debriefs ask:
- What was confusing? (Not "what did you do wrong?")
- What information did you wish you had?
- What part of the procedure didn't make sense in the moment?
- What would make this easier next time?
Crew who feel safe surfacing problems will surface real ones. Crew who feel attacked will hide real ones. The first kind of crew can fix things; the second kind can't.
Run a drill every time someone joins
SOLAS only requires a drill within 24 hours if more than 25% of the crew has changed, but the better practice is to run a quick muster anytime any new crew joins the vessel. It doesn't have to be a full fire drill — even a five-minute "walk to your muster station and confirm your duties" exercise gets the new crew member oriented.
This is one of those things The Muster App makes trivially easy. Three minutes on Muster Control with the new crew member walking around the vessel, and they've physically experienced the route they'd take in an actual emergency. That's more training than most yachts give new crew before sailing.
Track patterns in the session log
After a few months of drills, the Muster Sessions page becomes a goldmine for spotting patterns. Look for:
- Crew who are repeatedly slow to muster — they may not know their station, or they may have a physical issue you don't know about
- Stations that are repeatedly under-staffed — your assignments may not match how crew actually move around the vessel
- Time-to-account trends — getting faster month over month means training is working; getting slower means complacency is creeping in
- Re-musters that uncovered different counts — if your first muster says 23 of 25 and your re-muster says 24 of 25, the first count was wrong. That's a process problem, not a counting problem.
None of this requires fancy analytics. Just open the Sessions page once a quarter and read through the last few drills.
Make drills part of the rhythm
The yachts where drills go best are the ones where drills are part of the normal weekly rhythm — not a special event, not a disruption, not something the crew dread. They're scheduled, they're predictable in cadence (even if not in scenario), and they're treated like any other professional activity on a working vessel.
The yachts where drills go badly are the ones where they only happen when the captain remembers, or right before an inspection. Those drills feel like punishment and produce nothing useful.
The Muster App can't make your safety culture good — that's on the master and the leadership team. But it can make it easier for a captain who wants a good safety culture to actually run, record, and review drills without it eating their week. That's the design intent, and that's the bar we hold ourselves to.
