Overview of Stena Superfast X

STENA SUPERFAST X is Stena Line’s latest permanent addition to the Irish Sea fleet, and was built as a sister ship to STENA SUPERFAST VII and VIII.  She has been in service on the Holyhead to Dublin route since March 2015, however in February 2016 she was temporarily deployed to Belfast in order to cover the refit/dry-docking period of the regular Belfast to Cairnryan vessels. As the first of the series to leave Superfast Ferries, STENA SUPERFAST X has had a very different career to the other Stena Superfast vessels, having now operated for no less than 7 different operators in the Baltic, North Sea, Mediterranean, English Channel, and finally the Irish Sea.

Early Years

SUPERFAST X was the final of 4 identical ships delivered to Superfast Ferries in 2001 and 2002 by the same German yard (the other of the 4 ships in the Superfast VII class was launched as SUPERFAST IX and is currently Marine Atlantic’s ATLANTIC VISION, operating in Canadian waters). STENA SUPERFAST X is unique among the four Superfast VII class ships in having no tips on her funnel wings.  This is due to a clause in the sale agreement between Superfast and Veolia/SNCM when she was sold from the Superfast Ferries fleet in 2007, as Superfast were fiercely protective of their brand at the time – the funnel wings where a key part of the Superfast branding. Having purchased SUPERFAST X for €112m as part of an unsuccessful attempt to win the contract to run the concession between Marseille and Corsica, SNCM renamed her JEAN NICOLI. They soon chartered her out to Tunisian operator COTUNAV for around three months before another short-term charter was agreed, the time with Greek operator ANEK Lines. It was no secret that SNCM wanted to sell rather than charter out the vessel, however.


At the end of December 2007, JEAN NICOLI was sold to French operator SeaFrance for future service between Dover and Calais at a price of €105m. SeaFrance intended for her to replace both SEAFRANCE MONET and SEAFRANCE MANET after conversion to a “day” ferry. The company had originally wanted to order a third newbuild based on the design of SEAFRANCE RODIN and SEAFRANCE BERLIOZ instead, but a lack of shipyard capacity and a projected cost of €150-200m (not to mention any newbuild would be unlikely to be delivered before 2011) forced them to look for an existing vessel which could be made suitable.

Conversion to a “day” ferry

Now renamed SEAFRANCE MOLIERE, the former JEAN NICOLI arrived at ARNO Dunkerque on April 8th 2008 for an extensive refit at a projected cost of €15m. This quickly rose to around €20m. MacGregor was brought in to convert the loading arrangements of the vessel to make them compatible with the ports at Dover and Calais, including the modification and reinforcement of the bow doors and total replacement of the stern doors with an offset sliding arrangement and removal of her stern ramp. An additional bow thrust unit was installed to improve manoeuvrability, taking her compliment to three as well as a single stern thruster. The biggest transformation came inside, however, and involved the replacement of cabins with public spaces and the refurbishment of existing areas.

SEAFRANCE MOLIERE eventually entered passenger service around 2 months later than planned during October 2008, with the delay attributed to technical problems. As soon as February 2009 she was sent to Brest for a further technical overhaul which would last almost a month.

Following the failure of a recapitalisation plan by parent SNCF which was blocked by the EU, it was announced that SeaFrance would be liquidated on 16th November 2011 with all vessels laid up at Calais. In February 2012, SEAFRANCE MOLIERE was moved to Dunkerque for further layup. In July she was sold to Scapino Shipping who renamed her MOLIERE and moved her to Tilbury. On October 24th 2012 DFDS Seaways announced that they had agreed to charter MOLIERE for their own Dover to Calais service as a replacement for DEAL SEAWAYS which had proven unsuitable for the Dover Strait service. After a short refit at ARNO Dunkerque and now renamed DIEPPE SEAWAYS, she replaced DEAL SEAWAYS on the 6th of November wearing a basic DFDS livery with a white hull instead of the blue worn by the rest of the DFDS fleet.

Sold again

At a longer refit in Gdansk lasting two and a half weeks during February 2014, DIEPPE SEAWAYS received the full DFDS livery at last. In May 2014 however, it was reported that she had been sold to Stena RoRo. With DFDS’s two year charter due to end that November there was speculation that Stena intended to deploy DIEPPE SEAWAYS within their own Stena Line network. In late August, MacGregor announced that they had been awarded a contract to convert DIEPPE SEAWAYS for Stena Line’s Holyhead to Dublin route, with DFDS confirming to the French press the following week that the vessel would be returned to her owners in November. It was not until December the 8th however until Stena Line confirmed in a press release that the vessel would be coming to Holyhead.

Stena Line and the return of the ‘superfast’ name

Stena had actually purchased the then DIEPPE SEAWAYS in January 2014 according to their financial summary, but the transaction wasn’t widely reported until May.  On expiry of the DFDS charter, DIEPPE SEAWAYS was sent to the Nauta ship repair yard in Gdynia, Poland for conversion to make her more suitable for replacing both STENA NORDICA and HSS STENA EXPLORER on the Holyhead to Dublin/Dun Laoghaire routes (the Dun Laoghaire route closed during 2014). This included extensive work to her interior accommodation, alterations to both the bow and stern loading arrangements (which had been adapted for the English Channel service by SeaFrance), new more efficient propeller blades, and a technical overhaul to bring the ship up to “Stena standards”." alt="STENA SUPERFAST X in dock at Gdynia, Poland, before departing for Holyhead Port to begin operations on the Holyhead-Dublin route.

Cargotec subsidiary MacGregor carried out the necessary work to the bow and stern loading arrangements again, undoing much of the work they had done just a few years earlier for SeaFrance. Birkenhead based MPE Interiors won the contract for refurbishing the passenger accommodation – a contract which involved more than 30 staff working over a four week period in both Gdynia and Holyhead. The resulting interior layout is somewhat different from that of STENA SUPERFAST VII and VIII, reflecting the longer voyage by the provision of a number of cabins on deck 8. Unlike as-built sisters STENA SUPERFAST VII and VIII, there was no requirement for increased free-height for high-sided freight vehicles on the Holyhead route, and so the deckheads of the vehicle decks of STENA SUPERFAST X were left intact, unlike the North Channel twins which needed major structural modifications on the upper vehicle deck.

STENA SUPERFAST X had a somewhat troublesome introduction to service at Holyhead, with teething issues leading to some delays and cancellations. There were also reports of some of the refurbishment still being completed in the early weeks of her service, with rumours she had been rushed into service due to a charter having already been agreed with DFDS for one of the vessels she replaced, STENA NORDICA, which would, in turn, replace the former DIEPPE SEAWAYS at Dover. Freight drivers, in particular, were initially very critical of the vessel due to a perceived lack of cabin berths on busier sailings. However, in time STENA SUPERFAST X has proven to be a reliable vessel, and in 2018 even sailed at times when STENA ADVENTURER and Irish Ferries’ ULYSSES had been cancelled. Some minor changes have also been made to her accommodation in response to passenger feedback since her introduction, such as the redesignation of one of her cinemas on Deck 8 as a commercial drivers lounge.

North Channel service

In February 2016, STENA SUPERFAST X acted as the refit relief vessel for STENA SUPERFAST VII and STENA SUPERFAST VIII with mixed success. Her smaller restaurant and truckers restaurant which together occupy a space solely dedicated to the ‘Taste’ restaurant on the regular vessels seemed to be a particular source of complaints. For 2017 STENA NORDICA, which had by then returned to Stena Line, provided refit cover instead with more success despite her lower passenger capacity.

It is expected that STENA SUPERFAST X will be replaced in early 2020 by the first of Stena’s new E-Flexer ships STENA ESTRID, currently under construction in China.  At present it is unknown whether STENA SUPERFAST X will stay in the Stena Line fleet afterwards, or be offered for sale/charter by sister company Stena RoRo.
