A muster drill is a mandatory safety briefing held before or shortly after a cruise ship departs, showing passengers their muster station and lifeboat procedures. Yes, it is 100% required by international maritime law — you cannot skip it, and the ship will track whether you've completed it.

You just boarded your cruise ship, your cabin is gorgeous, the pool deck is calling, and then an announcement tells you to report to a safety drill. Yes, it's mandatory. No, you can't skip it to grab a drink first. Here's everything you need to know about muster drills — including how cruise lines have made them far less painful in recent years.
What Is a Muster Drill and Is It Actually Mandatory?
A muster drill (also called a safety drill or lifeboat drill) is a required safety briefing that every passenger must complete before or shortly after a cruise ship leaves port. It covers where your assigned muster station is, how to put on a life jacket, and what to do in an emergency.
Yes, it is 100% mandatory. Under SOLAS (Safety of Life at Sea) international maritime law, cruise lines are legally required to conduct a muster drill within 24 hours of departure — and passengers are required to attend. The ship tracks compliance. If you haven't checked in at your muster station, crew members will come find you in your cabin, the bar, or wherever you're hiding.
Refusing to participate can result in being denied boarding on future sailings and, in some cases, being removed from the ship at the next port.
| Drill Format | Time Required | When It Happens | Lines Using It |
|---|---|---|---|
| Traditional All-Hands Drill | 30–45 minutes | Before departure (everyone at once) | Older sailings, some smaller lines |
| Digital/eMuster (app-based) | 15–20 minutes | Before departure (at your own pace) | Royal Caribbean, Celebrity, MSC, Norwegian |
| Hybrid (video + station check-in) | 20–30 minutes | Before or shortly after departure | Carnival, Princess, Holland America |
| In-Cabin Video + Muster Check-in | 15–20 minutes | Within 24 hrs of sailing | Disney, Virgin Voyages |

What Factors Affect How the Drill Works?
The cruise line matters a lot. Since 2020–2021, most major cruise lines overhauled their muster drill process after the pandemic forced them to find non-crowded alternatives. What you experience today depends heavily on which line you're sailing.
- Royal Caribbean's eMuster: Watch a safety video on the Royal Caribbean app or stateroom TV, then check in at your assigned muster station. The whole thing takes about 15 minutes and can be done before the ship even leaves port.
- Carnival's Carnival HUB App Drill: Similar hybrid approach — watch the video on your phone or TV, then physically check in at your muster station with a crew member scanning your SeaFun card.
- Norwegian's Digital Muster: Watch the safety briefing on the NCL app or stateroom TV, then check in at your station. Must be completed before the ship departs.
- Traditional drill: On some smaller or expedition lines, you'll still assemble everyone in one spot, life jackets on, for the full group briefing. Expect 30–45 minutes.
Your muster station assignment is fixed. You don't get to choose it. It's printed on your key card and in your cabin documents. This is the specific assembly point you'd report to in an actual emergency, usually a deck area near a set of lifeboats.
Life jackets at your station or in your cabin. Depending on the ship, life jackets are either stored in your cabin (you bring them to the drill) or located at the muster station itself. Your drill briefing will clarify this — pay attention.

Practical Tips to Get Through Muster Drill Without It Ruining Your Embarkation Day
1. Do it as early as possible. On lines with digital muster (Royal Caribbean, Norwegian, Celebrity), you can complete the video portion before the ship even leaves the dock. Knock it out while you're still finding your sea legs — don't let it hang over you.
2. Download the cruise line's app before you board. Most modern muster drills now run through the official app. Having it ready means you complete the video portion in your cabin or wherever you are, not in a crowded hallway.
3. Read your cabin card on embarkation day. Your muster station is printed right on your room key. Find it on the ship map so you're not scrambling when the announcement comes.
4. Don't try to skip the physical check-in. Watching the video is only half the requirement on hybrid systems. You still have to physically show up at your assigned muster station for a crew member to scan your card or check you off. This is the part people try to skip — and get caught.
5. Bring kids' attention to the drill. If you're sailing with children, make sure they understand the basics too. On Disney Cruise Line especially, they make the drill fairly engaging for families — but kids still need to be present and accounted for.
6. Don't drink heavily before the drill. You need to actually absorb this information. Life jacket procedures, muster station location, what the emergency signals mean — this isn't theater. Real emergencies happen on cruise ships.
What to Expect by Cruise Line in 2025–2026
| Cruise Line | Drill Format | Approx. Time | App Required? | Notes |
|---|---|---|---|---|
| Royal Caribbean | eMuster (digital) | ~15 min | Yes (RC App) | Most streamlined in the industry |
| Celebrity Cruises | eMuster (digital) | ~15 min | Yes (Celebrity App) | Same system as Royal Caribbean |
| Carnival | Hybrid (video + check-in) | ~20–25 min | Carnival HUB app recommended | Can also watch on stateroom TV |
| Norwegian | Digital muster | ~15–20 min | NCL app | Must complete before departure |
| Princess | OceanReady digital | ~20 min | MedallionClass app | Very smooth process |
| Disney | In-cabin video + station | ~20–25 min | DCL Navigator app | Family-friendly presentation |
| MSC | Hybrid | ~25–30 min | MSC for Me app | Station check-in required |
| Holland America | Traditional/hybrid | ~30–35 min | Optional | More traditional experience |
| Virgin Voyages | In-cabin video | ~15 min | Sailor app | Most laid-back presentation |
| Expedition/Small Ships | Traditional | 35–45 min | No | Full group assembly, life jackets on |
The bottom line: muster drill is non-negotiable, but in 2025 it's a far cry from the sweaty 45-minute group sessions of the past. On most major lines, you can knock it out in 15–20 minutes on your phone before the ship even leaves port. Just don't be the person who tries to skip the station check-in — the crew will hunt you down, and that's genuinely embarrassing.
