Three vessels were ultimately completed in 1996 and 1997. The first of the class, Stena Explorer, entered service in April 1996, serving the Holyhead - Dún Laoghaire route[1] and As of 2014 remains the only one still in service. Two others had served Stranraer to Belfast and Harwich to Hoek van Holland.[2] On the 200-kilometre Hoek–Harwich route, the Stena HSS had cut the crossing time in half by cruising at 41 knots.[2][3]

Design and construction

Stena Explorer was constructed by Finnyards in Rauma, Finland.[4][5]

The HSS 1500 is a semi-small-waterplane-area twin hull (SWATH) catamaran, and was designed with the aim of providing a comfortable and fast service.[6]

Power is provided by four GE Aviation gas turbines in a twin COGAG configuration.[7] The vessels employ four Kamewa waterjets for propulsion.[1]

The HSS class of ferries were designed to allow quick turnarounds at port, in 30 minutes or less.[2] A specially designed linkspan for the Stena HSS provides ropeless mooring and allows quick loading, unloading and servicing. Vehicles are loaded via two of the four stern doors and park in a "U" configuration. When disembarking, vehicles drive straight off via the other two doors.[1]
