MV Wolfe Islander IV is a hybrid[1] ferry serving between Kingston, Ontario and Wolfe Island in the Great Lakes. It replaces the ferry MV Wolfe Islander III and brings 50% more capacity.[2][3] Wolfe Islander IV was constructed alongside another ferry, Amherst Islander II, using the same hybrid technology.[3][1]
Wolfe Islander IV is a Damen 9819 E3[4] built at the Damen Galați shipyard in Romania.[1][2] After being handed over to the Ontario Ministry of Transportation in August 2021,[5] it was originally anticipated to be brought into full-time service in mid 2022, but faced several delays due in part to crew shortages and incomplete docking infrastructure.[6] The ferry eventually began full-time service on August 17, 2024,[7] however, as of September 2025 it has faced two major incidents that have taken it out of service for multiple months to do repairs.[8][9]
