Are Cruise Ships Safe? An Honest Answer on Illness, Crime and Accidents

Updated 25 October 2026 · 5 min read · Cruise Questions Canada editorial team

Yes, cruise ships are safe by most measures, and the dramatic incidents that make the news are rare. The risks worth planning for are much more ordinary: a stomach bug, a slip on a wet deck, too much sun or alcohol, and a medical bill that Canadians often aren't insured for.

How safe are cruise ships, really?

Ships are built and operated under SOLAS, the International Convention for the Safety of Life at Sea. It covers fire protection, lifeboat and life-raft capacity for everyone aboard, crew training and the muster drill every passenger must attend (see what happens at the muster drill).

On top of the ship's flag state, port authorities inspect too. The US Coast Guard examines foreign-flagged ships carrying passengers from US ports, and Transport Canada inspects foreign ships in Canadian ports. Ships built since 2010 also follow "safe return to port" rules, designed so a ship can still sail to safety under its own power if a fire or flood knocks out one section.

What the crew is trained for

Crews run regular emergency drills, and announcements use codes so they can respond without alarming passengers. What the emergency announcements mean decodes the common ones.

The risks worth planning for

Seasickness belongs on the list for some people, though it is rarely serious; how bad seasickness really is covers remedies.

Norovirus: why you hear about it so much

Ships calling at US ports must report gastrointestinal illness, and the US Centers for Disease Control and Prevention has long published outbreak reports when a set share of passengers or crew fall ill. That transparency is one reason cruise outbreaks make headlines while ones in hotels, schools and care homes often don't.

Norovirus spreads mostly by hands and surfaces. Soap and water beats the hand sanitizer stations, so use the washroom sinks before eating, and report symptoms to the medical centre rather than hiding them.

Going overboard and crime at sea

The US Cruise Vessel Security and Safety Act applies to ships embarking or disembarking passengers at US ports. It requires railings at least 42 inches (about 107 cm) high, peepholes and security latches on cabin doors, and reporting of serious crimes to US authorities. Overboard incidents are rare and almost always involve someone climbing, sitting on or leaning over a railing, often after drinking.

Crime does happen, as it does in any small town. Sensible habits help: don't leave drinks unattended, meet new acquaintances in public areas and use the cabin safe.

Medical care at sea

Every large ship has a medical centre with a doctor and nurses who can stabilize most emergencies. Care is billed in US dollars to your account, and serious cases may need evacuation by helicopter or a hospital stay in port. The costs are set out in cruise ship medical care.

Your personal safety routine

1. Attend the muster and walk the route from your cabin to your station once.
2. Wash your hands with soap before every meal.
3. Buy travel medical insurance before you leave Canada.
4. Wear shoes with grip on deck and use handrails when the ship is moving.
5. Pace your drinking, and never sit on or lean over a railing.
6. Lock passports and valuables in the cabin safe.
7. Know the all-aboard time in every port and get back early.

Weather and the bigger picture

Ships reroute around storms, which is why itineraries sometimes change; what happens when a hurricane threatens explains how lines handle it. For most first-timers, the honest answer is that a cruise is a safe holiday, and the precautions that matter are the same everyday ones you would take anywhere.
