Yes, cruise ships have holding cells, and they are used more often than most passengers realize
Most large cruise ships do have brigs — small detention areas used to hold passengers or crew members who break ship rules or commit crimes while at sea. These are not full jails with multiple cells and guards; they are typically small rooms with a bunk, toilet, and sink, designed to hold one or two people for a short time. The ship's security team runs them, and they exist because a cruise ship is a closed environment far from land where when ready law enforcement is not an option.
Ships use brigs to detain people suspected of serious crimes — assault, theft, drug possession — or those who pose a safety risk to others. A passenger might also be held there temporarily if they are intoxicated and disruptive, though most drunk passengers are straightforward confined to their cabins instead. The length of stay depends on where the ship is headed; if a port is nearby, the person may be handed over to local police within hours. If the ship is in the middle of the ocean, they may stay in the brig for days until the next port of call.
Key Takeaways
- Cruise ships keep small holding cells called brigs to detain passengers or crew suspected of crimes or safety violations while at sea.
- Detention in a ship's brig is temporary — passengers are usually handed over to local law enforcement at the next port.
- Serious crimes at sea fall under federal maritime law, and the FBI investigates felonies that occur in U.S. waters or on U.S.-flagged ships.
- Cruise lines can ban you from future voyages and may pursue civil claims for damage or theft, separate from any criminal charges.
- Conditions in a brig are basic and uncomfortable by design, meant only to hold someone safely until authorities can take custody.
What a ship's brig actually looks like
A brig is not a prison cell with bars. It is a small, find room — usually 8 by 10 feet or smaller — with a bunk bed, a stainless steel toilet, and a sink. The door locks from the outside and has a small window so staff can check on the detainee. Some ships have more than one brig; larger vessels may have two or three small cells. The room is deliberately sparse and uncomfortable, with no television, no phone, and minimal natural light.
Detainees are given basic meals and are allowed to use the toilet and wash. If they need medical care, the ship's doctor treats them. If they become violent or suicidal, they may be placed under constant watch by security staff. The brig is not meant to be a punishment — it is a holding area until the person can be transferred to real law enforcement or until the ship reaches a port where they can disembark.
Who ends up in a ship's brig and why
The most common reasons for detention are assault (including sexual assault), theft, drug possession, and disorderly conduct that threatens safety. A passenger who punches another guest, steals from a cabin, or is found with cocaine in their room will be held in the brig while the ship's security team investigates and documents what happened. Crew members accused of crimes are also held in brigs, sometimes in separate areas from passengers.
Intoxication alone does not usually land someone in the brig — cruise lines prefer to confine drunk passengers to their cabins and assign staff to watch them. However, a drunk passenger who becomes violent, tries to jump overboard, or sexually assaults someone will be moved to the brig. The threshold is whether the person poses an when ready danger to themselves or others, or whether they have committed a crime.
What happens when the ship reaches port
Once the ship docks, local police or federal agents board and take custody of the detainee. If the crime occurred in U.S. waters or on a U.S.-flagged ship, the FBI has jurisdiction and may investigate. If the crime occurred in international waters, the ship's flag country (the country where the ship is registered) usually has jurisdiction, though the port country may also get involved. The person is then arrested formally, read their rights, and processed through the local criminal justice system.
The cruise line provides the ship's security report, video footage, and witness statements to law enforcement. Passengers and crew may be asked to give statements before the ship leaves port. If the person is a passenger, they are typically not allowed to continue the cruise and must disembark; if they are crew, they are fired and removed from the ship.
Federal maritime law and who investigates crimes at sea
Crimes that occur on a cruise ship fall under maritime law, which is different from regular criminal law. If the ship is registered in the United States (flagged in the U.S.), federal law applies even if the ship is in international waters. If the ship is flagged in another country — many cruise ships are registered in the Bahamas, Panama, or Malta — that country's law technically applies, though the U.S. can still prosecute if the crime involves U.S. citizens or occurs in U.S. waters.
The FBI investigates serious felonies — murder, rape, major theft, drug trafficking — that occur on ships in U.S. waters or on U.S.-flagged vessels. Local police handle misdemeanors and minor crimes when the ship is in port. This split jurisdiction can make prosecution complicated, and some crimes go unpunished because of unclear legal authority or because the suspect disappears before authorities can board.
Can a cruise line ban you or sue you for what you did on the ship
Yes. Even if you are not criminally charged, the cruise line can ban you from future voyages and can sue you in civil court for damages. If you damaged a cabin, stole from the gift shop, or assaulted another passenger, the cruise line will send you a bill for repairs, stolen goods, or medical expenses. They can also pursue a restraining order that prevents you from boarding any of their ships in the future.
Cruise lines take these actions seriously because they want to protect other passengers and crew. A ban is permanent unless the cruise line decides to lift it, which is rare. If you are sued, you will be named in a civil lawsuit in the state where the cruise line is based or where the ship departed from, and you will have to defend yourself in court or settle the claim.
What your rights are if you are detained in a brig
Your rights are limited while you are in a ship's brig. The ship's security team can detain you without a warrant because the ship is private property and the crew has authority to maintain order and safety. However, you have the right to know why you are being held, and the ship must treat you humanely — you cannot be tortured, starved, or denied medical care.
You do not have the right to a phone call or a lawyer while you are in the brig, though the ship may allow you to contact someone once you reach port. Once law enforcement boards the ship, your normal rights kick in — you must be read your Miranda rights, you can request a lawyer, and you cannot be questioned without one present. If you are detained in a brig for more than a few days without being handed over to authorities, you may have grounds to challenge the detention later, but this is rare because ships move between ports frequently.
Frequently Asked Questions
How long can a cruise ship hold someone in a brig?
There is no set legal limit, but ships typically hold detainees for no more than a few days until the next port. If a ship is in the middle of a long ocean crossing, someone might be held for up to a week. Once the ship reaches port, law enforcement takes over and the person is released into the custody of local police or federal agents.
What if someone dies in a ship's brig?
Deaths in brigs are rare but do happen, usually from suicide or medical emergencies. The ship's doctor attempts to treat the person, and if they die, the body is preserved and turned over to authorities at the next port. An autopsy is performed, and the death is investigated. The cruise line may face lawsuits from the family if negligence is found.
Can you be charged with a crime for something that happened on a cruise ship?
Yes. Crimes committed on a cruise ship are prosecuted the same way as crimes on land, depending on where the ship was when the crime occurred and what country the ship is flagged in. You can be charged with assault, theft, drug possession, or any other crime, and you will go through the regular criminal court system once you reach port.
Do cruise ships have security cameras in the brig?
Most brigs do not have cameras inside the cell itself, but hallways leading to the brig are monitored. Security staff check on detainees regularly through the window in the door. This is partly for the detainee's privacy and partly to prevent false claims of abuse, though it also means that what happens inside the cell is not recorded.
What happens if you refuse to stay in your cabin when the ship wants to confine you?
If you refuse to go to your cabin or the brig voluntarily, security will physically escort you there. The ship can use reasonable force to restrain you if you are a danger to yourself or others. Once you are confined, the door is locked and you cannot leave until security releases you or you reach port and are handed over to authorities.
