VICTORIA -- BC Ferries is celebrating Earth Day with the launch of its newest hybrid-power vessel. The ferry fleet’s sixth diesel-electric vessel has entered the water in Romania and will be the last Island Class vessel to join the ferry service next year. The new ship is expected to serve the Nanaimo-Gabriola Island route in early 2022. The yet-unnamed vessel is scheduled for sea trials in August before delivery to Victoria later this year. “We are excited to reach this milestone in our Island Class project,” said BC Ferries vice-president of shipbuilding Jamie Marshall in a statement Thursday. “The launch of the sixth and final vessel in the series propels BC Ferries closer to reaching its goal to be efficient and environmentally responsible throughout the system,” Marshall added.
