In 1972, Stena Line was one of the first ferry operators in Europe to introduce a computer-based reservation system for the travel business area.

[citation needed] In 1996, Stena Line introduced its 20,000 tonne HSS (High-speed Sea Service) vessels, which operated: Belfast–Stranraer; Holyhead–Dún Laoghaire and Hook of Holland–Harwich.

[citation needed] In November 2006, Stena ordered a pair of "super ferries" with a gross tonnage of 62,000 from Aker Yards, Germany for delivery in 2010, with an option for two more ships of the same design.

They are due to begin service in Autumn 2025, giving an 80% boost in capacity to the current ships at 147 metres (482 ft) long with 2,800 lane meters.
