Finnish marine and energy equipment manufacturer Wärtsilä will supply the electric propulsion system for three electric, high-speed ferries that will operate in the San Francisco Bay area.

Shipyard All American Marine (AAM) placed the order on behalf of San Francisco Bay Ferry, California’s largest public ferry operator.

The three vessels will be the first delivered as a part of San Francisco Bay Ferry’s Rapid Electric Emission Free (REEF) Ferry Program. They will operate on new routes connecting two of San Francisco’s fastest-growing neighborhoods, Treasure Island and Mission Bay, to SF Bay Ferry’s Downtown SF ferry hub. Wärtsilä will work within the REEF project team to finalize the vessel and charging system concepts.

Wärtsilä will supply the full electric propulsion system. This includes the energy and power management system (EPMS), the integrated automation system (IAS), batteries, DC Hub, transformers, electric motors and the shore power supply. The Wärtsilä equipment is scheduled for delivery commencing in 2026 and the first vessel is expected to join the ferry fleet in early 2027.

“These 150-passenger ferries represent a step forward in sustainable and innovative marine transportation. As we look to the future of this project, we are relying upon Wärtsilä’s advanced technologies and extensive expertise to continue driving its success,” said Ron Wille, President, All American Marine.
