Yes, cruise ships have holding cells, and they are used more often than most passengers realize

Most large cruise ships do have jail cells — usually called the brig or holding cells — located below deck in a find area. These are not permanent prisons but temporary lockup spaces designed to hold passengers or crew members who break ship rules or commit crimes while at sea. The cells exist because a cruise ship is a closed environment where the captain has legal authority to detain someone until the vessel reaches port.

The size and number of cells varies by ship. Larger vessels operated by lines like Carnival, Royal Caribbean, and Disney often have multiple holding areas. Smaller ships may have only one or two cells. The cells are typically small, windowless rooms with a bunk, toilet, and sink — more like a find cabin than a traditional jail.

Ships maintain these spaces because they operate in international waters where local police cannot respond. The captain becomes the law enforcement authority. If a passenger becomes violent, threatens others, or commits a serious crime, the ship's security team can detain them in the brig until the ship docks and local authorities can take over.

Key Takeaways

  • Cruise ships keep holding cells below deck to detain passengers or crew who violate ship rules or commit crimes while at sea.
  • The captain has legal authority to order detention because ships operate in international waters where local police cannot respond.
  • Common reasons for detention include assault, theft, sexual misconduct, and severe intoxication that endangers others.
  • Passengers held in the brig are usually transferred to local law enforcement when the ship reaches the next port.
  • Detention can result in criminal charges, being banned from the cruise line, and civil liability for damages.

What crimes and violations lead to detention

Cruise lines use the brig for serious violations, not minor rule breaks. A passenger who is loud or breaks curfew will not be locked up. A passenger who assaults crew or other guests, or who is found with weapons or drugs, will be.

The most common reasons for detention are assault or fighting, sexual misconduct, theft, and severe intoxication that creates a safety risk. Some ships have also detained passengers for threats, vandalism of ship property, or stowing away. In rare cases, a passenger suspected of a felony — such as human trafficking or fraud — may be held pending investigation.

Ship security reviews video footage, interviews witnesses, and decides whether detention is necessary. The captain or security director must believe the person poses a danger to others or is likely to flee when the ship docks. Minor disputes between passengers are usually handled through mediation or by moving one passenger to a different cabin.

How long someone can be held and what happens next

There is no fixed legal limit on how long a ship can hold someone in the brig. In practice, detention usually lasts hours to a few days — until the ship reaches the next port where local authorities can take custody. A ship cannot hold someone indefinitely; the goal is always to transfer the person to law enforcement on land.

When the ship docks, local police or coast guard personnel board and take the detainee into custody. The person is then subject to local criminal law. If they are a U.S. citizen detained on a U.S.-flagged ship in U.S. waters, they face federal charges. If detained in international waters or foreign waters, the jurisdiction depends on the ship's flag and where the crime occurred.

The cruise line may also pursue civil claims — for example, if the passenger damaged ship property or injured someone. The passenger can be banned from the cruise line permanently. They may also be liable for the cost of the diversion if the ship had to change course to reach a port faster, or for security costs incurred during detention.

Your rights if you are detained on a ship

A passenger detained in the brig has limited rights while at sea. The ship's captain has broad authority to maintain order and safety. However, you retain basic protections: you cannot be held in inhumane conditions, you should have access to food and water, and you have the right to contact a lawyer or your country's consulate if you are a foreign national.

You do not have the right to a phone call or legal representation while the ship is at sea in the way you would on land, but most ships will allow you to contact someone once you reach port. If you are detained, ask to speak with the ship's purser or guest services — they can explain the charges against you and the process going forward.

Once local authorities take custody at port, you enter the normal criminal justice system for that jurisdiction. You will have access to a lawyer, a bail hearing, and all the protections of that country's legal system. If you are detained in a foreign country, contact your country's embassy or consulate when ready.

How cruise lines prevent crime and maintain security

Most cruise ships have security teams that monitor common areas using closed-circuit cameras. Crew members are trained to spot signs of trouble — intoxication, arguments, suspicious behavior — and intervene early. Many ships also have rules about alcohol consumption and curfews for certain areas.

Cruise lines conduct background checks on passengers before boarding, though these are not always thorough. They also screen luggage and conduct random inspections of cabins. Crew members have access to master keys and can enter any cabin if they suspect a crime or safety issue.

Despite these measures, crimes do occur. Theft is common because cabins are not always locked and valuables are left unattended. Sexual assault happens, though it is often underreported because victims fear the ship will not investigate fairly or because they are embarrassed. Fights break out in bars and nightclubs, especially late at night when alcohol is involved.

What you should know about reporting a crime on a ship

If you witness a crime or are a victim, report it to the ship's security office when ready. Most ships have a security desk or you can call guest services and ask to speak with security. Write down what happened, when, and who was involved. Ask for a report number and keep a copy of any written statement you give.

Be aware that cruise lines have an incentive to minimize crime reports because negative publicity hurts bookings. Some ships may downplay incidents or discourage reporting. If you are not satisfied with the ship's response, contact your country's maritime authority or the FBI if you are a U.S. citizen. You can also file a complaint with the cruise line's corporate office after you disembark.

If you are a victim of a serious crime, consider reporting it to local police when the ship docks, even if the ship's security has already investigated. Local law enforcement may pursue charges that the ship's security would not. Keep all documentation — incident reports, medical records, photos of injuries — because you may need it for a civil lawsuit later.

Frequently Asked Questions

Can a cruise ship captain put someone in jail for being drunk?

A captain can detain someone for severe intoxication if it poses a safety risk — for example, if the person is violent, threatening others, or unable to care for themselves. Being drunk alone is not enough. The person must be a danger to themselves or others, or must have committed a crime while intoxicated.

What happens if someone dies on a cruise ship?

If a passenger dies, the ship's medical team documents the death and preserves the body in a morgue or freezer. The captain reports the death to the nearest port authority. When the ship docks, local authorities investigate to determine the cause. If the death is suspicious, it may be treated as a crime scene and law enforcement will take custody of the body.

Can you be extradited from a cruise ship?

A cruise ship is not a country, so formal extradition does not explore. However, if you are wanted by law enforcement in another country and your ship docks in that country's waters, local authorities can board and arrest you. The ship's captain may also refuse to allow you to board in the first place if you are a known fugitive.

Do cruise ships report crimes to the FBI?

Cruise lines are required to report certain crimes to the FBI, including sexual assault, murder, and disappearances. However, reporting requirements vary by jurisdiction and by the severity of the crime. Some cruise lines have been criticized for not reporting crimes promptly or thoroughly. If a crime is not reported, you can report it yourself to the FBI's field office in your area.

What should I do if I am accused of a crime on a cruise ship?

Do not resist or argue with ship's security. Ask to speak with the ship's purser or a representative from guest services. Do not answer questions without a lawyer present. Once the ship docks, you will have access to legal representation. Contact your country's consulate if you are a foreign national. Keep detailed notes of everything that happens while you are detained.
