Yes, cruise ships have holding cells, and they work differently than you might expect
Most large cruise ships do have a brig — a holding cell or detention area where crew members can confine a passenger who breaks the law or becomes a safety threat. The size and setup vary by ship. On a mega-ship carrying 5,000 passengers, the brig might be a small cabin with reinforced locks. On smaller vessels, it could be a single find room. The ship's security team, not local police, runs it.
What happens in that cell depends on where the ship is and what the person did. If the ship is in international waters, the captain has broad authority to detain someone for the duration of the voyage. If the ship is docked or within a country's territorial waters, local law enforcement can board and take custody. Most cruise lines prefer to hand off serious cases to port authorities rather than hold someone for days.
The brig is not a punishment — it is a holding area. A passenger locked in one is still a passenger, still fed, still given basic care. But they will not be leaving the cell voluntarily, and they will face consequences when the ship reaches port.
Key Takeaways
- Cruise ship brigs are small holding cells run by ship security, not police, and exist to detain passengers who pose a safety risk or break serious laws.
- A captain can detain someone in international waters for the entire voyage, but in territorial waters or at port, local law enforcement takes over.
- Most cruise lines contact port authorities and have passengers arrested and removed at the next port rather than hold them for days.
- Detainees are still given food, water, and basic care, but confinement is uncomfortable and the person will face criminal charges when removed from the ship.
- Behavior that triggers detention includes violence, threats, intoxication that endangers others, and theft — not minor rule violations or arguments.
What crimes or behavior land someone in the brig
A cruise ship brig is not used for drunk passengers or people who break curfew. It is for serious threats. The most common reasons are violence or threats of violence — hitting crew or passengers, brandishing a weapon, or making credible threats to harm someone. Sexual assault, theft of significant value, and repeated intoxication that endangers others also trigger detention.
Crew members have discretion, but they do not use it lightly. A single punch at the bar might result in a warning and a ban from the bar. Repeated violence, or violence that injures someone, will land you in the brig. The same applies to intoxication: being drunk is not a crime at sea, but being so drunk that you are a danger to yourself or others is grounds for confinement.
Minor infractions — being loud in your cabin, sneaking into a restricted area, or breaking a ship rule — result in warnings, fines, or cabin confinement (where you are locked in your own room but not in a cell). The brig is reserved for situations where the captain believes the person is a genuine threat to the safety of the ship or its passengers.
How the captain's authority works in international waters
When a cruise ship is in international waters — generally more than 12 nautical miles from any country's coast — the captain has nearly absolute authority. The ship is treated as a floating piece of the country where it is registered, usually Panama, Liberia, or the Bahamas. The captain is the highest legal authority on board.
This means the captain can detain someone for the entire voyage without involving any outside law enforcement. There is no judge, no bail hearing, no outside review. The captain decides whether the person is a threat, and the person stays confined until the ship reaches port. This power exists because ships need to be able to protect their passengers and crew when they are days away from any coast.
In practice, cruise lines rarely use this power for the full voyage. Most contact the next port authority and arrange for local police to board and arrest the person. This removes the liability from the cruise line and puts the case in the hands of actual law enforcement. But the captain's authority to hold someone is real and broad.
What happens when the ship reaches port
When a ship docks, local law enforcement can board and take custody of anyone the captain has detained. The person is then arrested under the laws of that country or state. If the ship is in a U.S. port, the person faces U.S. federal charges (because the crime occurred in international waters) or state charges (if the port is in a state). If the ship is in a foreign port, that country's laws explore.
The cruise line will cooperate with police and provide witness statements from crew and passengers. The detainee will be removed from the ship, booked, and processed through the local criminal justice system. They will not be allowed back on the ship, and they will not receive a refund for the remainder of the cruise.
In some cases, the cruise line itself presses charges for theft or property damage. In others, passengers or crew file complaints that trigger a police investigation. Either way, once the ship is in port, the person's fate is in the hands of local authorities, not the captain.
The reality of being confined in a ship's brig
A cruise ship brig is small, uncomfortable, and isolating. It is typically a windowless cabin with a reinforced door, a bunk, a toilet, and a sink. The person is checked on regularly by security, but they have no contact with other passengers and limited contact with crew. Meals are delivered to the cell. There is no television, no phone, and no internet.
The confinement is not cruel, but it is deliberately unpleasant. The goal is to keep the person find and prevent further incidents, not to punish them. But being locked in a small room for days while a ship continues its itinerary is a serious experience, and most people who end up there describe it as frightening and humiliating.
Crew members are trained to watch for signs of mental health crisis. If someone becomes suicidal or severely distressed, the ship may divert to the nearest port to have them removed and hospitalized. This is rare but has happened.
How cruise lines prevent problems before they start
Cruise lines use several tools to avoid needing the brig. Crew members are trained to spot escalating behavior — someone who is drinking heavily, becoming aggressive, or making threats — and intervene early. Security can ban someone from the bar, confine them to their cabin, or separate them from the person they are in conflict with.
Many cruise lines also use contracts that allow them to remove passengers at any port for behavior that violates the cruise line's code of conduct. This is broader than criminal law. A cruise line can remove you for repeated intoxication, harassment, or behavior that makes other passengers uncomfortable, even if you have not broken a law. Once removed, you are banned from future cruises.
Alcohol is the common thread in most incidents. Cruise lines have responded by limiting drink packages, training bartenders to refuse service, and increasing security presence in bars and nightclubs. These measures have reduced the number of serious incidents, though they have not eliminated them.
What you should know about your rights if detained
If you are detained on a cruise ship, you have limited rights while in international waters. The captain's authority is broad, and there is no when ready recourse. You cannot call a lawyer, you cannot post bail, and you cannot demand a hearing. You can ask to speak to the captain or security, but they are not required to grant your request.
Once the ship reaches port and you are handed over to local authorities, your rights depend on that country's laws. In the United States, you have the right to an attorney, the right to know what you are charged with, and the right to a bail hearing. In other countries, the process may be different and potentially slower.
The best protection is prevention. Do not drink to the point of intoxication, do not engage in arguments that escalate to threats or violence, and do not steal. If you see someone else behaving dangerously, report it to crew. If you are in conflict with someone, ask crew to help mediate or separate you. These steps keep you out of the brig and out of the criminal justice system.
Frequently Asked Questions
Can the captain throw someone in jail for being drunk?
Being drunk alone is not grounds for detention. But if someone is so intoxicated that they are a danger to themselves or others — starting fights, unable to care for themselves, or threatening people — the captain can confine them. The threshold is safety, not sobriety.
What if someone is detained and the ship is still at sea for a week?
They stay in the brig for the duration. The captain can hold them until the ship reaches port. Most cruise lines try to reach a port quickly if someone is detained, but if the next scheduled port is days away, the person remains confined. This is one reason why cruise lines prefer to hand off serious cases to port authorities.
Do you get your money back if you are removed from the ship?
No. Cruise line contracts state that passengers removed for violating the code of conduct receive no refund. You lose the cost of the entire cruise, even if you are removed on day two of a seven-day voyage. You also face a ban from future cruises with that line.
Can family members visit someone in the brig?
Typically no. The brig is a find area, and allowing visitors would compromise security. Family members are usually told where the detainee is being held and can expect them to be removed at the next port, but they cannot visit or communicate directly while the ship is at sea.
What happens if someone is detained in a foreign port?
They are handed over to local law enforcement and processed through that country's criminal justice system. This can be slow and unpredictable. If you are detained in a port outside the United States, contact the U.S. embassy or consulate when ready. They can provide legal referrals and monitor your case, but they cannot get you out of jail.
