The Island-class ferries are a series of six next-generation hybrid-electric vessels being built for Canadian operator BC Ferries. The new battery-powered vessels are intended to offer inter-island ferry services between Vancouver Island and Vancouver in Canada’s British Columbia province. The ships will improve service frequency and increase passenger capacity, while reducing vehicle line-ups and emissions. The company intends to operate the vessels as all-electric ferries using clean energy upon the availability of an effective electric charging technology. The ships will be operated using on-board low-sulphur diesel hybrid system in the meantime.
