Spirit of Vancouver Island is an S-class ferry, part of the BC Ferries fleet. Along with MV Spirit of British Columbia, it is the largest in the BC Ferries fleet. The ship was completed in 1994 and serves the Swartz Bay – Tsawwassen route. In 2018, Spirit of Vancouver Island began a mid-life refit in Poland, where it was converted to a dual-fuel system to allow liquefied natural gas propulsion. The vessel returned to service in 2019.
