'''S-class ferries''' (also known as the '''Spirit class''' or '''Super ferries''') are [[roll-on/roll-off]] (RORO) [[ferries]] operated by [[BC Ferries]] in [[British Columbia]], Canada. They are the largest ferries in the BC Ferries fleet. The class comprises two ships, {{MV|Spirit of British Columbia||2}} and {{MV|Spirit of Vancouver Island||2}}, which were completed in 1993 and 1994 respectively. They serve the ferry route between [[Tsawwassen Ferry Terminal|Tsawwassen]] and [[Swartz Bay Ferry Terminal|Swartz Bay]]. In 2017, the class underwent conversion to a dual-fuel propulsion system that would allow them to use either [[Marine diesel oil|marine diesel]] fuel or [[liquefied natural gas]].
