If you are planning a sailing and wondering whether you can vape on board, the honest answer is yes, sometimes, but usually only in specific places. This article is for adult vapers, smokers considering switching, and travellers who want to avoid breaking ship rules by mistake. I have to be honest, this is one of those questions where people often assume vaping is treated casually because it is not smoking, but ferry and cruise operators usually take a much stricter approach than that. Across current ferry and cruise policies, the most common rule is that vaping is allowed only in designated smoking areas, usually on open deck, while cabins, balconies, and enclosed public spaces are commonly prohibited.
The Short Answer
Yes, you may be able to vape on ferries and cruise ships, but normally only in designated areas. On ferries, operators such as Brittany Ferries, DFDS, and Irish Ferries say smoking and vaping are restricted to designated outdoor areas, and not allowed in enclosed indoor spaces. On cruises, lines such as P&O Cruises and Cunard say e cigarettes are permitted only in designated smoking areas, with cabins, balconies, and public rooms generally off limits. In my opinion, the safest assumption is simple. Do not expect to vape wherever you like on board, even if you are carrying a legal reusable device.
Why The Rules Are Usually Strict
Ship operators tend to treat vaping as a safety, comfort, and enforcement issue rather than only a smoking issue. Cruise lines often want one clear onboard rule that avoids confusion for staff and passengers, and ferry operators do the same. There is also the practical problem that vapour can trigger smoke detectors in enclosed spaces, which is why indoor use is commonly restricted. For me, this is the part many travellers miss. Even if vaping is less harmful than smoking in wider public health terms, that does not mean a ship operator wants clouds in cabins, corridors, stairwells, or lounges.
What The Ferry Rules Usually Look Like
Ferry policies are often fairly straightforward. Brittany Ferries says all enclosed areas of its ships are non smoking and that electronic cigarettes are also not permitted in those areas, while passengers may smoke on outdoor decks. DFDS says smoking and vaping are prohibited onboard unless you are in a designated area on the outside deck. Irish Ferries says smoking is not permitted in any inside passenger area and that the same rule applies to electronic cigarettes, with outside passenger decks used for dedicated smoking areas. I would say ferries are usually easier to understand than cruises, because the rule is often simply inside no, designated outside area yes.
What The Cruise Rules Usually Look Like
Cruise policies are similar in principle, but often stricter in detail. P&O Cruises says smoking is not permitted in cabins, on cabin balconies, or in public rooms, and that e cigarettes are permitted in designated smoking areas only. Cunard says electronic cigarettes and vaporising devices are only permitted in designated smoking areas, and its onboard information also says smoking, including electronic alternatives, is not permitted in staterooms, on stateroom balconies, or in other non smoking areas. MSC Cruises warns that repeated smoking in non designated areas can ultimately lead to disembarkation, showing that cruise enforcement can be more serious than many people expect.
Can You Vape In Your Cabin
Usually no. This is one of the clearest patterns across cruise lines, and it is also a bad assumption to make on overnight ferries. P&O Cruises says e cigarettes are prohibited in cabins in the same way as cigarettes. Cunard says smoking and vaping are not permitted in staterooms. Royal Caribbean says smoking or vaping is not permitted inside any stateroom, and breaking that rule can trigger a cleaning fee of 250 US dollars and further action. I have to be honest, if you are wondering whether a quick discreet puff in the cabin is fine, the answer is usually no, and the penalties can be expensive.
Can You Vape On Your Balcony
Normally no on cruise ships, and you should not assume yes on ferries just because you have outside access. P&O Cruises says smoking is not permitted on cabin balconies, and Cunard says smoking and vaping are not permitted on stateroom balconies. Royal Caribbean says smoking or vaping is not permitted on stateroom balconies either. For me, balcony rules are among the ones passengers break most often because they assume it is private outdoor space, but operators clearly do not see it that way.
Where You Usually Can Vape
The most common permitted place is a designated smoking area on the open deck or outside deck. P&O Cruises says vaping is allowed in designated smoking areas only, and Cunard says designated smoking areas on the open decks will be clearly signposted. DFDS says there will be signs onboard showing where you can and cannot smoke or vape, and Irish Ferries points passengers to outside decks with dedicated smoking areas. In my opinion, this is the practical rule to remember. If it is not clearly marked as a smoking or vaping area, assume it is not allowed.
Why Designated Areas Matter So Much
Designated areas are not just about etiquette. They help crew manage fire safety, airflow, and passenger comfort, and they make enforcement much easier. Cruise lines such as Cunard and P&O Cruises are explicit that smoking and vaping are confined to these zones, and some operators attach penalties to breaches. Royal Caribbean warns of a cleaning fee for cabin violations, while MSC warns repeated smoking in unauthorised areas can lead to disembarkation. I would say this is the strongest reason not to treat the rules casually. On a ship, staff have very little patience for passengers who decide to invent their own vaping area.
Do All Operators Have The Same Policy
No, and that is where travellers get caught out. The broad pattern is similar, but the exact wording and enforcement differ by operator. Brittany Ferries and DFDS focus clearly on designated outside deck areas. P&O Cruises and Cunard say designated smoking areas only, including for e cigarettes that do not emit visible smoke. Royal Caribbean’s wording is slightly different in style, but still prohibits vaping in cabins and on balconies. For me, the lesson is that the broad answer is useful, but the individual operator’s policy still matters before you travel.
What About Carrying Vapes On Board
In general, bringing a vape on board is usually different from being allowed to use it anywhere. Most operator policies focus on where you may vape, not on a blanket ban on possession. That said, onboard rules can tighten depending on route, local laws, and destination ports. Cunard specifically notes that some countries have strict rules around electronic cigarettes, which matters because cruise itineraries cross multiple jurisdictions. I suggest treating possession and permitted use as two separate questions, because a device that is allowed in your luggage may still only be usable in a very limited area once you are sailing.
Health And Regulation In The UK Travel Context
In the UK, vaping remains a regulated consumer product mainly intended for adult smokers, but ship rules are a separate issue. Ferry and cruise operators can impose tighter onboard restrictions than the general law on land. It is also worth keeping the current market position accurate. Single use vapes are banned from sale and supply in the UK, so current travel questions should really be thought about in relation to legal reusable products rather than newly sold disposables. In my opinion, that distinction matters because travel articles often recycle old advice without reflecting the current UK product landscape.
Common Misconceptions
One common misconception is that because vaping is not smoking, it is usually allowed in cabins. Current ferry and cruise policies do not support that. Another is that if you have a balcony, vaping there must be fine. Again, many cruise lines specifically ban it. There is also a tendency to think a quick puff will not matter, but onboard policies often treat any use outside designated areas as a rule breach whether or not anyone nearby complains. I have to be honest, ships are one of the worst places to rely on assumptions.
A Balanced Final View
Can you vape on ferries and cruise ships. Usually yes, but only in designated areas, most often on outside deck smoking sections. Indoor areas, cabins, and balconies are commonly banned, especially on cruise ships, and operators can impose fees or stronger penalties for breaking the rules. For me, the clearest takeaway is this. You can often bring your vape, but you should expect to use it only where the operator explicitly allows it, not where it feels convenient.
