Which is Better: Irish Ferries or Stena Line?

If you are choosing between Irish Ferries and Stena Line, the answer depends first on where you are travelling. Holyhead to Dublin is the clearest head-to-head comparison because both operators sail the route. Elsewhere on the Irish Sea, your departure and destination will often make the decision for you.

For Holyhead–Dublin, Stena Line currently has the stronger independent passenger score and a slightly shorter crossing than Irish Ferries' conventional ferries. Irish Ferries has the speed advantage when its seasonal Dublin Swift fast ferry is operating. Families, pet owners and foot passengers have a few other differences worth knowing before choosing.

Irish Ferries vs Stena Line: The Quick Verdict

Where Can You Actually Choose Between Irish Ferries and Stena Line?

Stena Line operates more Irish Sea routes, but that does not automatically make it the better ferry company for your journey. On several routes there is no direct choice between these two operators at all.

If Belfast is your destination, Stena Line is the relevant choice between these two companies. If you want Pembroke–Rosslare, Irish Ferries has the direct service. For travellers who can use either Holyhead–Dublin service, the differences between the operators become much more useful.

Which Is Faster From Holyhead to Dublin?

Irish Ferries has the fastest individual ferry when Dublin Swift is operating, but Stena is currently slightly quicker than the conventional Irish Ferries services.

Stena Line advertises its Holyhead–Dublin crossing at around 3 hours 15 minutes. Ships used on the route include Stena Estrid and Stena Adventurer.

Irish Ferries' current October schedule shows Ulysses and James Joyce making the crossing in around 3 hours 30 minutes. You can check the current timetable through the Irish Ferries Holyhead–Dublin sailing information.

The difference becomes much larger when Dublin Swift is operating. The seasonal fast ferry takes around 2 hours 15 minutes, which can cut more than an hour from a conventional crossing.

That makes Irish Ferries particularly attractive when speed matters and Dublin Swift is running at a convenient time. It should not, however, be treated as a year-round two-hour service. On the October 2026 sailings we checked, Ulysses and James Joyce were operating instead.

Which Is Cheaper: Irish Ferries or Stena Line?

Neither operator is consistently cheaper. Ferry prices move with the date, departure time, vehicle, passenger numbers, availability and fare conditions.

Published starting prices for 2026 were extremely close when we checked, but they were based on different conditions and therefore did not provide a fair enough comparison to declare a winner.

Rather than repeat the full price analysis here, we have compared fare types, published prices, fees, Tesco Clubcard rules and other costs separately in our Stena Line vs Irish Ferries price comparison.

If you are travelling Holyhead–Dublin, price both operators for the same passengers, vehicle and similar departure time. A cheap headline fare is less useful if it is for a sailing you do not want or a ticket that costs more to amend later.

Which Has the Better Onboard Experience?

Both operators use substantial cruise ferries on Holyhead–Dublin, so the difference is more subtle than a simple checklist of restaurants, shops and seating.

Stena Estrid and Stena Adventurer

Stena Estrid has en-suite cabins, Stena Plus, the quieter Hygge recline lounge, restaurants, shopping, movie lounges, a children's Happy World area and a game zone. Stena Adventurer also provides cabins, Stena Plus and Hygge seating.

One useful difference is the choice between Stena Plus and Hygge. Someone who wants somewhere quieter than the main passenger areas without paying for a private cabin can choose a recliner in the Hygge lounge, while Stena Plus offers the more premium lounge experience.

You can see the current route and ship information through Stena Line's Holyhead–Dublin page.

Ulysses and James Joyce

Irish Ferries' Ulysses has private en-suite cabins, Club Class, restaurants, bars, shopping, children's facilities and two cinema screens. James Joyce also offers cabins, Club Class, restaurants, shopping and family facilities.

Ulysses is particularly useful for travellers wanting a private cabin on a relatively short crossing, while Club Class gives passengers another option if they want a quieter space without booking accommodation.

The latest independent evidence gives Stena a small advantage. In Which?'s 2026 ferry survey, Stena Line Holyhead–Dublin received a 71% customer score, compared with 68% for Irish Ferries. Stena also scored more strongly for facilities and customer service on the route.

The difference is only three percentage points, so we would treat this as a narrow advantage rather than evidence that one operator provides a dramatically better crossing. You can see the Which? ferry survey for the full results.

Which Is Better for Families and Travelling With Children?

There is no strong overall winner for families. Both companies have children's facilities on their main Holyhead–Dublin cruise ferries, and both offer cabins and upgraded lounge options.

The more important difference may be the type of crossing you choose.

A family wanting the shortest possible time at sea may prefer Dublin Swift when its schedule works. A family wanting more space, a private cabin or somewhere for children to move around may prefer one of the larger conventional ships.

Stena Estrid has a dedicated children's Happy World area alongside movie and game facilities. Ulysses has children's facilities, cinemas and private cabins. For a family of four, therefore, we would compare the actual ship as well as the operator.

This matters particularly on Holyhead–Dublin because choosing Irish Ferries does not always mean travelling on the same vessel. A Dublin Swift journey is a different proposition from travelling on Ulysses or James Joyce.

Which Is Better if You Are Taking a Dog?

Both Irish Ferries and Stena Line allow pets, but the facilities depend on the ship and route.

Stena provides pet-friendly cabins on its Holyhead route. On Stena Estrid, pets using these cabins can access a dedicated outside area for fresh air and toilet breaks. On Stena Adventurer, pets booked into a pet-friendly cabin must remain in the cabin during the crossing.

You can check the current arrangements through Stena Line's pet-cabin information.

Irish Ferries' Ulysses has a Pet Den, including access to an outside area, as well as other pet-travel arrangements depending on the booking and vessel. You can see the current facilities through the Irish Ferries Ulysses information.

For pet owners, we would therefore avoid choosing purely by brand. Check which ship operates the sailing and what pet accommodation is available on it. A pet-friendly cabin may be worth more than a small fare saving if you would otherwise have to use a kennel or different pet arrangement.

What About Foot Passengers?

Both operators accept foot passengers on Holyhead–Dublin, but travelling without a car makes some practical details more important.

Stena says foot passengers at Holyhead and Dublin are transferred between the passenger terminal and ferry by shuttle bus. Irish Ferries also has luggage-handling facilities specifically for foot passengers on the Holyhead–Dublin route.

Irish Ferries currently allows up to two checked suitcases per foot passenger, each weighing no more than 22kg. Larger bags are placed into the luggage system at check-in and cannot be accessed during the crossing, so anything needed onboard should stay in your hand luggage.

For either operator, we would look beyond the ferry fare and check how the sailing connects with the rest of the journey. A departure that works neatly with a train to Holyhead or onward transport from Dublin Port may be more useful than saving a few pounds on a less convenient sailing.

Which Has More Flexible Tickets?

Both companies separate their cheapest tickets from fares offering more flexibility.

Irish Ferries currently charges £20 per car journey to change the date, route or sailing on an Economy ticket, plus any increase in fare. Stena also charges for certain Economy amendments.

If your dates may move, compare Flexi with Flexi rather than simply choosing whichever company shows the lowest Economy price. Paying slightly more upfront can sometimes cost less than changing a restrictive ticket later.

Irish Ferries Club or Stena Extra: Which Gives Better Value?

The two loyalty schemes start surprisingly close together.

For an occasional customer, there is little between them on the basic reward rate. Spend £200 on eligible travel and the starting-level earning is roughly equivalent to £10 towards future travel with either scheme.

The difference becomes more relevant for frequent travellers. Irish Ferries Club increases its earning rate considerably at Silver and Gold level, while Stena Extra Gold combines its higher points rate with benefits that can include lounge or cabin savings.

If you only make one ferry trip a year, loyalty probably should not determine which operator you choose. If you cross regularly, it deserves a place in the calculation.

Do You Need a Passport for Irish Ferries and Stena Line in 2026?

Yes, on the affected Britain–Republic of Ireland services. This is an important change since the original version of this comparison was published.

From 28 September 2026, passengers travelling between Britain and the Republic of Ireland on these routes must present a valid passport or Irish passport card before boarding.

Irish Ferries states that this applies to passengers on its Republic of Ireland–Britain services, including British and Irish citizens and children. Its current Holyhead–Dublin sailing information also gives a latest check-in time of 30 minutes before departure.

Stena Line carries the same passport warning for its Holyhead, Dublin, Fishguard and Rosslare services.

If you have travelled this route before using another form of identification, do not assume the old rules still apply.

So, Which Is Better: Irish Ferries or Stena Line?

For a conventional Holyhead–Dublin crossing in October 2026, we would give Stena Line a narrow overall advantage. Its advertised crossing is around 15 minutes shorter than the current Irish Ferries cruise-ferry schedule, and it scored slightly better in the latest Which? passenger research.

There are several situations where we would choose differently:

• Choose Irish Ferries when Dublin Swift is operating at a useful time if getting across as quickly as possible is the priority.
• Consider Stena if you value the choice between Stena Plus, Hygge seating and private cabins on the conventional crossing.
• Check the actual ship if travelling with a dog. Pet-friendly cabins, Pet Den facilities and outside access vary by vessel.
• Families should compare the ship rather than just the brand. Dublin Swift offers speed, while the larger conventional ferries provide more space and facilities for a longer crossing.
• Foot passengers should consider the complete journey. Ferry time, train connections, terminal transfers and onward travel from Dublin can matter more than a small difference in ticket price.
• If price is the deciding factor, check both operators. Neither has demonstrated a permanent price advantage.

Outside Holyhead–Dublin, the route often matters more than the operator. Stena's wider Irish Sea network makes it the obvious choice between these two companies for Belfast, while Irish Ferries operates the direct Pembroke–Rosslare crossing.

Check Current Irish Ferries and Stena Line Offers

If you have decided which operator and sailing suits the journey, it is worth checking whether there is a current promotion before paying. Our Irish Ferries voucher codes and offers and Stena Line voucher codes and offers pages contain the latest savings we have available.

A voucher should not determine which ferry you use if the route, sailing time or fare conditions are wrong for the trip. Compare the actual booking first, then see whether an applicable offer reduces the cost.

When an eligible purchase made through My Favourite Voucher Codes earns us a commission, that income contributes to our overall profits. We donate 20% of our monthly profits to charity, at no extra cost to the traveller.
