Several patents were registered to Stena Line in the development of the HSS, along with Stena Explorer three other HSS vessels were completed. Stena Voyager and Stena Discovery were built to operate around the British Isles with Stena Carisma built for Scandinavian use. The newest of the craft was re-named HSS Discovery after being sold to a ferry company in Venezuela during 2009.
