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. Her regular route is from Holyhead in Wales to Dublin, 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.
SUPERFAST X was the final of 4 identical ships delivered to Superfast in 2001 and 2002 by the same 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 because they had to be removed as part of the sale arrangement between Superfast and Veolia/SNCM, as Superfast were fiercely protective of their brand at the time – the funnel wings where a key part of the Superfast branding.
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. Although Stena purchased the then DIEPPE SEAWAYS in January 2014, she had an existing charter with DFDS which didn’t expire until November that year. On expiry of the DFDS charter DIEPPE SEAWAYS went to the Nauta ship repair yard at Gdynia, Poland for conversion to make her more suitable for replacing both STENA NORDICA and HSS STENA EXPLORER on the Holyhead to Dublin/Dun Laoghiare 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 propeller blades, and a technical overhaul to bring the ship up to Stena standards. The resulting interior layout is somewhat different to that of STENA SUPERFAST VII and VIII, reflecting the longer voyage by the provision of a number of cabins on deck 8.
It is expected that STENA SUPERFAST X will be replaced in early 2020 by the first of Stena’s new E-Flexer ships, 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.
