20 Ultimate No-Nos of Cruise Packing—Learn What’s Banned

When packing for a cruise, you might be tempted to bring all the comforts of home—from your favorite snack foods to your trusty hair iron. However, cruise ships have strict rules about what passengers can bring aboard, designed to ensure all travelers’ safety, security, and comfort.

I stress to all of my cruise clients that they should be sure to read and re-read the prohibited packing list. It would be a shame to ruin their vacation over a packing mistake.

To help you avoid any boarding day mishaps, it’s important to familiarize yourself with these prohibited items. Many travelers have faced delays and other complications for packing items that, while seemingly harmless, violate cruise line policies.

Below is a detailed rundown of common but surprising items you should leave out of your suitcase. You’ll notice that most of the items are related to fire danger, as fire is the #1 worst disaster that can happen at sea.

1. Firearms and Ammunition

Due to safety concerns, firearms of any type, including replicas, are strictly prohibited on cruise ships. Violation of this rule can lead to arrest and disembarkation. For instance, passengers have been detained and faced legal action after security screenings discovered firearms in their luggage.

2. Sharp Objects

Knives with blades over 4 inches are generally banned, except for those used for personal grooming. Cruise lines implement this policy to prevent potential harm. Past incidents include a passenger not being allowed to board after security found a large hunting knife in their checked bag.

This includes knives you purchase at ports as souvenirs, although in that case, you can give them to security, and they will keep them until you disembark on the final day.

3. Illegal Drugs and Substances

Carrying drugs, including marijuana and CBD products, is forbidden regardless of their legal status in some places. This aligns with international maritime law. Passengers caught with these substances can face severe penalties, such as immediate removal from the ship and legal charges in the next port.

4. Alcohol

Alcohol like beer and spirits is typically prohibited to avoid undercutting onboard bar sales. Wine may be allowed with limitations. In some instances, passengers have had their spirits confiscated until the end of their voyage as a consequence.

5. Household Appliances

Items such as toasters and coffee makers are banned due to fire risks. Fire incidents on ships have been traced back to such appliances, leading to strict enforcement of this policy.

Fans for your cabins are also not allowed, but in some cases, you can ask your room steward for one if you want to have a fan while sleeping.

6. Candles and Incense

Open flames from candles and incense can create fire hazards. In past cases, items like these were confiscated to prevent the risk of fire aboard the ship, where such an event could be catastrophic.

7. Hoverboards and Segways

These are banned for safety reasons, as their use can lead to accidents on crowded decks. Reports of injuries associated with hoverboards have prompted these bans.

Heely shoes are also not allowed on board; you must remove the wheels if you bring them.

8. Drones and Kites

Due to safety and privacy concerns, these items are usually not allowed on ships, though they may be kept for use onshore. Improper use can lead to accidents or invasions of privacy, leading to their confiscation.

Be sure and check the laws where you are going, but also each individual cruise line, as some are banning drones even if you don’t use them on board.

9. Irons and Steamers

These are prohibited because they pose fire hazards. Passengers needing these services are typically directed to onboard laundry services. Ignoring this rule can lead to fines and confiscation of the items.
