The most common crime on cruise ships is sexual assault. In the first quarter of 2025 alone, sexual offenses accounted for 33 of the 48 alleged crimes that cruise lines were required to report to U.S. federal authorities, and across the full year of 2025, 131 sexual offenses were reported on ships departing from or arriving in the United States, up from 120 the year before.1USA TODAY. Reports of Sexual Assault on Cruise Ships Rose Last Year Congress recognized this pattern when it passed the Cruise Vessel Security and Safety Act, noting that sexual assault and physical assault had been the leading crimes investigated by the FBI on cruise vessels for the five years before the law was enacted.2Congress.gov. Public Law 111-207 – Cruise Vessel Security and Safety Act of 2010 The ranking has not changed since.
Why Sexual Offenses Lead the Numbers
The Q1 2025 breakdown is stark. The Department of Transportation recorded 23 allegations of rape and 10 additional sexual assaults, compared with 7 aggravated assaults and 7 thefts over $10,000.3U.S. Department of Transportation. Cruise Vessel Security and Safety Act Statistical Compilation January 1, 2025 – March 30, 2025 Sexual offenses outnumber every other category combined.
Several features of cruise life push the numbers in that direction. Alcohol flows freely in a vacation atmosphere, which lowers inhibitions and impairs judgment. Thousands of strangers share tight quarters around the clock, and the social dynamic encourages quick familiarity. Corridors are often empty late at night. Victims can feel isolated because they’re far from their normal support network and local police. None of this excuses the conduct, but it helps explain why the pattern holds year after year.
One caveat matters for reading these numbers. They capture only the crimes cruise lines must report by federal law. Petty theft, minor fights, and low-level fraud are handled internally by ship security and rarely show up in any public data set. Sexual assault tops the official statistics in part because it is among the most serious offenses that trigger mandatory reporting in the first place.
Other Crimes Reported at Sea
Aggravated assault is the second most common category. The seven incidents in Q1 2025 ranged in type: these can be alcohol-fueled passenger fights or attacks by crew members.3U.S. Department of Transportation. Cruise Vessel Security and Safety Act Statistical Compilation January 1, 2025 – March 30, 2025 Ship security responds first and can detain individuals, but the FBI handles the formal investigation when U.S. nationals are involved.
Theft over $10,000 tied with aggravated assault at seven reports that quarter. The $10,000 figure is a statutory cutoff: only thefts exceeding that amount must be reported to the FBI and Coast Guard. Smaller thefts of electronics, jewelry, or cash from unlocked cabins are far more common but are resolved internally. The size of modern vessels, some carrying over 5,000 passengers, makes surveillance coverage imperfect despite extensive camera systems.
Missing-person cases are rare but draw the most public attention. One U.S. national was reported missing from a cruise ship during Q1 2025. These cases trigger a multi-agency response and can involve anything from an accidental fall overboard to suspected foul play.
What Federal Law Requires Cruise Lines to Report
The Cruise Vessel Security and Safety Act, signed in 2010, created the mandatory crime-reporting obligations the industry now operates under. It applies to any passenger vessel authorized to carry 250 or more passengers with overnight accommodations that embarks or disembarks passengers in the United States.4Justia Law. 46 USC 3507 – Passenger Vessel Security and Safety Requirements That covers essentially every major cruise ship sailing from a U.S. port.
Under the law, cruise lines must report the following alleged crimes to the FBI and the U.S. Coast Guard:
- Homicide
- Suspicious death
- Missing U.S. national
- Kidnapping
- Assault with serious bodily injury
- Sexual offenses, covering rape, aggravated sexual contact, and related federal crimes
- Firing or tampering with the vessel
- Theft of money or property exceeding $10,000
The statute also requires cruise lines to log theft complaints over $1,000 and other crime complaints in a separate internal record. A cruise line that fails to comply faces civil penalties of up to $25,000 per day the violation continues, capped at $50,000 for an ongoing violation.4Justia Law. 46 USC 3507 – Passenger Vessel Security and Safety Requirements The Department of Transportation publishes the reported data in quarterly statistical reports available to the public.
Your Rights If You’re the Victim of a Crime on Board
The CVSSA gives victims of sexual assault specific rights that the cruise line cannot deny. The ship must maintain anti-retroviral medications and sexual assault examination supplies on board, along with credentialed medical staff who can perform a forensic examination.5GovInfo. Cruise Vessel Security and Safety Act of 2010 The results of that examination must be documented in writing and signed by the patient.
The cruise line must also give the victim free and immediate access to a private telephone line and an internet-connected computer to confidentially contact law enforcement, an attorney, or the National Sexual Assault Hotline.4Justia Law. 46 USC 3507 – Passenger Vessel Security and Safety Requirements This matters because ship-to-shore communication normally costs money, and a victim who doesn’t know about this right might hesitate to reach out. The ship must also provide contact information for the FBI, Coast Guard, the nearest U.S. consulate or embassy, and third-party victim advocacy services.
Every passenger is also entitled to a written security guide before the voyage that describes the medical and security staff available 24 hours a day, explains the jurisdictional rules that apply to crimes at sea, and lists contact information for relevant law enforcement authorities.4Justia Law. 46 USC 3507 – Passenger Vessel Security and Safety Requirements Few passengers read it. If you sail regularly or travel with family, it’s worth reviewing before you leave port.
What to Do If a Crime Happens on Your Cruise
Report to ship security immediately. Even if you’re unsure whether what happened rises to a crime, creating an official record matters. Ship security will document the incident, preserve evidence like surveillance footage, and initiate the required notifications to the FBI and Coast Guard.6U.S. Coast Guard. Guidance for Completion of Cruise Line Report of Alleged Serious Violations of US Law If you wait days to report, physical evidence and camera footage may be lost.
For sexual assault victims, request the medical examination the cruise line is legally required to provide at no cost. Ask for the private phone and internet access you’re entitled to under federal law, and use it to contact the FBI, the Coast Guard, or the National Sexual Assault Hotline (1-800-656-4673). You are not required to use ship security as your only channel to law enforcement. For passengers on voyages embarking or disembarking in the United States, you have the right to contact the FBI or Coast Guard independently.4Justia Law. 46 USC 3507 – Passenger Vessel Security and Safety Requirements
Photograph any injuries. Write down what happened while your memory is fresh, including names of witnesses, the time, and the location on the ship. If you went to the ship’s medical center, keep copies of all paperwork. This documentation becomes critical later when the FBI investigates and when an attorney evaluates whether you have a civil claim.
Which Country’s Laws Apply
Jurisdiction over crimes at sea is genuinely complicated, and the answer often disappoints victims. The default authority belongs to the “flag state,” meaning the country where the ship is registered, which has exclusive jurisdiction over vessels flying its flag under international law.7National Oceanic and Atmospheric Administration. Jurisdiction Over Vessels Most major cruise lines register their ships in countries like the Bahamas, Panama, or Bermuda for tax and regulatory reasons.
That default shifts in two situations. First, every coastal nation’s sovereignty extends 12 nautical miles from its shoreline under the UN Convention on the Law of the Sea, so a crime committed while a ship is docked in Miami or sailing within 12 miles of the U.S. coast falls under American jurisdiction regardless of the ship’s flag.8United Nations. United Nations Convention on the Law of the Sea – Part II Second, under 18 U.S.C. § 7, the special maritime and territorial jurisdiction of the United States extends to any foreign vessel on a voyage scheduled to depart from or arrive in a U.S. port, as long as the offense was committed by or against a U.S. national.9Office of the Law Revision Counsel. 18 USC 7 – Special Maritime and Territorial Jurisdiction of the United States That provision is what allows the FBI to investigate crimes on foreign-flagged ships; agents typically try to board the vessel before it docks or shortly after arriving at a U.S. port to secure the scene and interview witnesses.10FBI. Crimes Against Americans on Cruise Ships
One important limit: the United States generally cannot board a foreign-flagged vessel on the high seas to enforce U.S. criminal law without consent from the flag state.10FBI. Crimes Against Americans on Cruise Ships If a crime happens mid-ocean on a Bahamas-registered ship, the FBI may have to wait until the vessel reaches a cooperating port. Evidence degrades in that gap, and this is where overlapping authorities create real problems for victims rather than theoretical legal puzzles.
