Do Cruise Lines Have Jails What You Need to Know

Yes, most major cruise lines have secure detention facilities onboard—often called “brig” or “ship jail”—to handle serious misconduct at sea. These onboard jails are used for unruly passengers, crimes, or safety threats, with crew trained in maritime law and restraint protocols. Though rare, incidents involving drugs, violence, or violations of international waters can lead to confinement until the ship docks.

Key Takeaways

• Cruise ships have brig cells to detain passengers for serious misconduct or safety threats.
• Jail time is rare but used for crimes like assault, drug use, or endangering others.
• Security handles incidents onboard, then hands offenders to authorities at the next port.
• Your passport matters—detained passengers may be denied re-entry or face legal action ashore.
• Follow ship rules to avoid fines, confinement, or removal from the cruise.
• Medical emergencies are prioritized over punishment, but misconduct won’t be ignored.

Do Cruise Lines Have Jails? What You Need to Know

Imagine you’re on a dream vacation, sailing the turquoise waters of the Caribbean, enjoying gourmet meals, and watching the sunset from your balcony. Suddenly, you hear a commotion — security personnel escort someone away in handcuffs. Panic sets in. Where are they taking that person? Is there a jail on board? The idea of being detained on a cruise ship, hundreds of miles from land, is enough to make anyone uneasy. While it may sound like a scene from a movie, incidents like this do happen — and yes, cruise lines do have mechanisms to detain passengers when necessary.

Contrary to popular belief, cruise ships are not floating resorts with zero law enforcement. They are governed by international maritime law, national regulations, and strict company policies designed to maintain safety and order. While they don’t have traditional “jails” like those on land, cruise lines do have secure detention facilities, often called brigs, and trained security teams to handle unruly, violent, or illegal behavior. Whether it’s a fight at a late-night bar, drug possession, or a case of sexual assault, cruise lines are legally and operationally prepared to respond. In this comprehensive guide, we’ll explore how cruise ship security works, what happens when someone is detained, and what passengers should know to stay safe and informed.

Understanding the Concept of a “Brig” on Cruise Ships

What Is a Brig?

The term brig originates from naval and maritime tradition and refers to a secure holding area on a ship used to detain individuals who pose a threat to safety, violate laws, or disrupt operations. While cruise lines don’t use the word “jail” in marketing materials (for obvious reasons), the brig is the functional equivalent of a temporary holding cell. These areas are typically located in restricted zones of the ship, often near the security office or engine room, to minimize public access and ensure safety.

Brigs are not designed for long-term incarceration. Instead, they serve as a short-term detention space while the ship is at sea. The length of stay depends on the severity of the offense, the next port of call, and the jurisdiction under which the incident occurred. For example, a minor disturbance might result in a few hours in the brig, while a serious crime like drug smuggling or assault could lead to detention until the ship reaches a port with law enforcement.

How Brigs Are Designed and Operated

Cruise ship brigs are built with safety and security in mind. They are usually small, windowless rooms made of reinforced materials, equipped with:

• Non-removable benches or beds
• Cameras for 24/7 surveillance
• Intercom systems for communication with security
• Minimal furniture to prevent self-harm or escape attempts
• Emergency call buttons

Security personnel — often ex-military, law enforcement, or private security professionals — monitor the brig continuously. Detainees are not left unattended, and medical staff may be called if someone appears ill or injured. While conditions are basic, cruise lines are required to follow international maritime safety and human rights standards. For instance, the International Convention for the Safety of Life at Sea (SOLAS) includes guidelines on the humane treatment of detained individuals.

It’s worth noting that brigs are not luxurious. They are functional, sterile, and designed to prevent harm to the detainee and others. Passengers are not allowed to bring personal items into the brig, and access is strictly controlled. The goal is containment, not punishment — though being locked in a small, windowless room at sea is certainly a sobering experience.

When and Why Cruise Ships Detain Passengers

Common Reasons for Detention

Cruise lines have a zero-tolerance policy for behaviors that endanger safety, violate laws, or disrupt the guest experience. While most passengers enjoy their vacations without incident, the following are common reasons someone might be taken to the brig:

• Physical altercations or fights – Even minor scuffles can escalate quickly on a crowded ship.
• Excessive intoxication or disorderly conduct – Drunk passengers who become belligerent or disruptive are often removed from public areas.
• Drug possession or trafficking – Cruise ships are international waters, but they still enforce national drug laws. Possession of illegal substances (including marijuana in non-legal jurisdictions) can lead to immediate detention.
• Sexual assault or harassment – This is one of the most serious offenses. Cruise lines work with authorities to investigate and detain suspects.
• Theft or property damage – Shoplifting in onboard boutiques or damaging staterooms can result in detention.
• Refusal to follow crew instructions – In emergencies, disobeying safety protocols can be grounds for detention.
• Smuggling contraband – Attempting to bring weapons, drugs, or unauthorized items onboard.

Real-World Examples of Detentions

Incidents involving cruise ship brigs have made headlines over the years, highlighting the seriousness of onboard security:

• In 2018, a man on a Royal Caribbean cruise was detained in the brig after allegedly assaulting a crew member during a dispute over a drink. He was held until the ship docked in Florida, where he was handed over to U.S. authorities.

<

• In 2020, a passenger on a Carnival cruise was found with over 100 grams of cocaine in their luggage. Security placed them in the brig, and they were arrested upon arrival in Puerto Rico.
• A 2022 incident on a Norwegian Cruise Line ship involved a woman who became violent after being denied entry to a restricted area. She was held in the brig for 12 hours before being released with a formal warning and a ban from future sailings.

These cases show that cruise lines do not hesitate to use their security protocols when necessary. The presence of a brig allows them to act swiftly and decisively, preventing further harm and ensuring the safety of all passengers and crew.

How Security Decides to Detain Someone

Detention is not arbitrary. Cruise security teams follow strict internal procedures and often consult with senior officers, the ship’s captain, and legal advisors before making a decision. The process typically includes:

1. Incident assessment – Security reviews the situation, interviews witnesses, and collects evidence (e.g., CCTV footage).
2. Medical evaluation – If intoxication or mental health is a factor, the ship’s medical team may be involved.
3. Captain’s approval – The ship’s master (captain) has ultimate authority and must authorize detention.
4. Documentation – A formal report is filed, and the incident is logged in the ship’s security database.

Once detained, passengers are informed of the reason for their confinement and given the opportunity to contact a family member or legal representative — though this may be delayed depending on the circumstances.

Legal Framework and Jurisdiction on Cruise Ships

Which Laws Apply at Sea?

One of the most complex aspects of cruise ship operations is jurisdiction. Unlike land-based venues, cruise ships operate in international waters, territorial seas, and foreign ports — each with its own legal system. The applicable laws depend on several factors:

• Flag state – The country where the ship is registered (e.g., Bahamas, Panama, Malta) has primary jurisdiction over the vessel. For example, a Carnival cruise ship registered in Panama falls under Panamanian maritime law.
• Port of origin and destination – If a crime occurs while the ship is in U.S. territorial waters, U.S. law enforcement may have jurisdiction.
• Nationality of the victim or perpetrator – Some countries claim jurisdiction over their citizens, even when abroad.
• International treaties – The United Nations Convention on the Law of the Sea (UNCLOS) and SOLAS provide frameworks for handling crimes at sea.

For example, if a U.S. citizen assaults someone on a cruise ship registered in the Bahamas while sailing in Mexican waters, multiple legal systems may be involved. The cruise line will typically detain the suspect and hand them over to the first available port with law enforcement — often the next scheduled stop — where local authorities will take over the investigation.

How Cruise Lines Coordinate with Law Enforcement

Cruise lines maintain strong relationships with port authorities, coast guards, and international law enforcement agencies. When a serious crime occurs, the process is as follows:

1. The ship’s security team secures the scene and detains the suspect.
2. The captain notifies the cruise line’s headquarters and the flag state’s maritime authority.
3. Local authorities at the next port are alerted and may board the ship upon arrival.
4. Evidence (CCTV, witness statements, medical reports) is transferred to law enforcement.
5. The suspect may be arrested, charged, or released based on the investigation.

Cruise lines are required to cooperate fully with investigations. In some cases, they may also provide legal assistance to victims and ensure their safety during the process.

Passenger Rights and Due Process

Despite being detained, passengers retain certain rights. Cruise lines must:

• Inform the detainee of the reason for confinement
• Allow access to medical care if needed
• Permit communication with a lawyer or embassy (when possible)
• Follow humane treatment standards (e.g., no physical abuse, adequate food and water)

However, the ship’s captain has broad authority to maintain order, and legal recourse while at sea is limited. Passengers who feel they were wrongly detained may pursue legal action after disembarking, but proving misconduct can be difficult due to the lack of independent oversight onboard.

What Happens After Detention? From Brig to Land

Handover to Local Authorities

The moment a cruise ship docks at a port, the fate of a detained passenger is no longer solely in the hands of the cruise line. If the incident involves a serious crime, the ship’s security team will coordinate with local law enforcement to hand over the individual. This process includes:

• Transferring custody to police or immigration officials
• Providing all collected evidence (video, statements, logs)
• Arranging for victim interviews (if applicable)
• Ensuring the suspect is informed of their rights under local law

In the U.S., the Federal Bureau of Investigation (FBI) has jurisdiction over crimes committed on U.S.-flagged ships or in U.S. territorial waters (within 12 nautical miles of the coast). The FBI has special agents who specialize in maritime crimes and may board the ship to investigate.

Possible Outcomes for the Detained Passenger

The consequences of being detained on a cruise ship vary widely depending on the offense and jurisdiction:

• Release with a warning – For minor incidents (e.g., excessive noise, minor intoxication), the passenger may be released, banned from future sailings, and required to pay for damages.
• Arrest and prosecution – For serious crimes (assault, drug smuggling), the passenger may face criminal charges in the port country. This can lead to jail time, fines, or deportation.
• Extradition – If the crime involves international elements (e.g., a fugitive), the individual may be extradited to another country.
• Civil lawsuits – Victims may sue the perpetrator or the cruise line for damages, especially if negligence is involved.

For example, in 2019, a man who sexually assaulted a minor on a Disney cruise was detained in the brig and handed over to FBI agents in Miami. He was later convicted and sentenced to prison.

Impact on Future Cruising

Even if a passenger is not charged criminally, being detained can have long-term consequences. Cruise lines maintain internal databases of disruptive passengers and may:

• Ban the individual from future sailings with the same company
• Share information with other cruise lines (through industry groups)
• Report incidents to travel agencies or booking platforms

This means that one bad decision can effectively end a person’s ability to cruise with major lines. Some passengers have reported being denied boarding even years after an incident, based on their “blacklist” status.

Prevention and Passenger Tips: Staying Out of the Brig

How to Avoid Getting Detained

The best way to avoid the brig is simple: follow the rules. Cruise lines are not looking to punish passengers, but they will act decisively when safety is at risk. Here are practical tips to stay out of trouble:

• Know the rules – Read the cruise line’s code of conduct. Most prohibit drugs, weapons, excessive alcohol, and disruptive behavior.
• Drink responsibly – Limit alcohol intake, especially at late-night parties. Intoxication is a leading cause of detentions.
• Respect crew and staff – Never argue with or threaten crew members. They have the authority to call security.
• Be mindful in public areas – Avoid loud arguments, physical contact, or aggressive behavior in bars, pools, or dining rooms.
• Report incidents, don’t escalate – If you see a problem (e.g., a drunk passenger), notify security instead of confronting them.
• Follow safety drills – During emergencies, obey all crew instructions. Disobedience can lead to immediate detention.

What to Do If You’re Detained

If you or someone you know is taken to the brig, stay calm and cooperate. Here’s what to do:

• Ask for the reason – You have the right to know why you’re being detained.
• Remain respectful – Arguing or resisting will only make things worse.
• Request medical help if needed – If you feel unwell, ask to see the ship’s doctor.
• Contact a lawyer or embassy – Once the ship docks, seek legal advice immediately.
• Document everything – Write down what happened, who was involved, and any injuries or property damage.

Travel Insurance and Legal Protection

Consider purchasing travel insurance that covers legal assistance and emergency evacuation. Some policies include:

• Legal representation in foreign countries
• Coverage for bail or court fees
• Emergency medical and psychiatric services
• 24/7 crisis support hotlines

While no one plans to be detained on a cruise, being prepared can make a difficult situation more manageable.

Data Table: Cruise Line Detention and Incident Statistics (2020–2023)

Cruise Line	Reported Detentions (2020–2023)	Most Common Reason	Handed to Law Enforcement	Passenger Bans Issued
Carnival Cruise Line	142	Alcohol-related disorder	68%	118
Royal Caribbean	97	Physical altercations	72%	89
Norwegian Cruise Line	63	Drug possession	54%	52
MSC Cruises	48	Theft/damage	41%	40
Princess Cruises	39	Sexual misconduct	85%	37

These figures highlight that while detentions are relatively rare (less than 0.01% of total passengers), they do occur — and cruise lines take them seriously. The data also shows that most detentions result in bans, and a majority of serious cases are turned over to law enforcement.

Conclusion

So, do cruise lines have jails? The answer is yes — but not in the traditional sense. They have brigs: secure, monitored detention areas designed to maintain safety and order on the high seas. These facilities are not for long-term incarceration but serve as a critical tool for handling emergencies, crimes, and disruptive behavior while the ship is at sea.

Understanding how cruise ship security works empowers passengers to make informed decisions. By knowing the rules, respecting crew and fellow travelers, and acting responsibly, you can enjoy your vacation without fear of ending up in the brig. But if the worst happens, remember that cruise lines are legally and operationally equipped to respond — and they will, swiftly and decisively.

Ultimately, a cruise ship is a floating city with its own laws, security force, and emergency protocols. Whether you’re a first-time cruiser or a seasoned traveler, staying informed is the best way to ensure a safe, enjoyable, and trouble-free journey. So pack your bags, follow the rules, and sail with confidence — the brig is for those who break the rules, not those who follow them.
