Do Cruise Ships Have Jails? Understanding the Security Measures at Sea

As a cruise specialist and frequent cruiser, I often receive questions that might seem surprising to those who haven’t spent much time at sea. One such question is, “Do cruise ships have jails?”

The answer is yes; cruise ships do have jails, often referred to as “brigs.” While it’s a topic that doesn’t come up often, it’s an important aspect of onboard security that every cruiser should understand.

Why Do Cruise Ships Have Jails?

With millions of passengers enjoying cruises each year, cruise lines must be prepared to handle a variety of situations, including those involving disruptive or unlawful behavior. While cruises are generally safe and enjoyable experiences, having a secure space to detain individuals who may pose a threat to others is a necessary precaution.

The brig on a cruise ship is a small, secure room designed to temporarily hold passengers or crew members who are involved in serious incidents, such as assault, theft, or other criminal activities. These jails are typically used very sparingly, as most issues can be resolved without needing to detain anyone.

Where is the Brig Located?

The brig is usually located on one of the lower decks of the ship, away from passenger areas, similar to the location of the morgue. This ensures that any security incidents are handled discreetly without disturbing the experience of other guests. The brig is equipped with basic amenities to ensure the safety and comfort of the detainee until the ship reaches the next port.

What Happens If Someone is Detained on a Cruise?

If someone on a cruise ship is involved in an incident that requires detention, the ship’s security team will first investigate the situation. This team is typically made up of trained professionals, often with backgrounds in law enforcement or the military, who are responsible for maintaining safety and order on board.

Once the decision is made to detain someone, they are placed in the brig under the supervision of the ship’s security personnel. The individual will remain there until the ship can dock at the next port, where local authorities will take over the situation. Depending on the severity of the incident, the detainee may face legal action, be disembarked, or be released with a warning.

Security and Safety on Cruise Ships


Cruise lines take the safety and security of their passengers and crew very seriously. The presence of a brig is just one part of a comprehensive security system that includes surveillance cameras, security personnel, and strict protocols for handling any issues that arise. Most passengers will never even be aware of these security measures, as they are designed to ensure a smooth and enjoyable cruising experience.

As someone who has spent years in the cruise industry, I can confidently say that incidents requiring the use of a brig are extremely rare. However, it’s reassuring to know that cruise lines are prepared for any situation, ensuring that the safety and well-being of all guests is their top priority.

What You Should Know Before You Cruise

While the idea of a jail on a cruise ship might sound unsettling, it’s important to remember that these facilities are in place to protect passengers and maintain order. For the vast majority of cruisers, the closest they’ll come to the brig is reading about it in posts like this one.

If you’re planning a cruise, focus on enjoying the incredible experiences that await you—whether it’s exploring exotic ports of call, relaxing on deck, or indulging in world-class dining. Knowing that your cruise line has robust security measures in place, including the presence of a brig, allows you to enjoy your vacation with peace of mind.

Cruises are among the safest and most secure forms of travel, with dedicated professionals ensuring that every journey is as enjoyable and worry-free as possible.
