Rolls-Royce has been chosen by Catalina Express of San Pedro, California, to supply propulsion systems for its new high-capacity ferry. The 500-passenger vessel, which will become the largest in the company’s fleet, will be powered by four mtu 12V4000 M65L engines, delivering over 7,463 kW (10,000 bhp).
The ferry is part of the Port of Los Angeles’ $31 million LA MER project, funded in partnership with the California Air Resources Board (CARB). Catalina Express received a $15 million state grant and matched it with its own $15 million investment. The initiative supports testing of technologies that reduce emissions as the Port works toward its zero-emission target.
Measuring 42 meters in length and capable of reaching 37 knots, the new vessel will replace three older ferries while maintaining passenger capacity and improving efficiency. It will also set new benchmarks for environmental performance within the Catalina Express fleet.
The EPA Tier 4-certified mtu Series 4000 M65L engines are known for fuel efficiency, quiet operation, and advanced emissions control. They will be paired with a selective catalytic reduction (SCR) system and, once certified by CARB, a diesel particulate filter (DPF) to meet California harbor craft regulations, alongside U.S. Coast Guard safety standards.
Catalina Express President and CEO Greg Bombard said the project continues the company’s 43-year commitment to sustainability. “We are proud to once again partner with Rolls-Royce to install newly designed Tier 4 mtu engines in our new vessel, further advancing our mission for cleaner marine transportation.”
The ferry is being designed by Incat Crowther of Lafayette, Louisiana, and built by Marine Group Boat Works of Chula Vista, California. Hamilton waterjets will be integrated with mtu’s monitoring and control systems, while MSHS Pacific Power Group of Washington will oversee installation, sea trials, and long-term service support. Engine deliveries are scheduled for late 2025, with the vessel expected to enter service in 2026.
Since its founding in 1981, Catalina Express has grown into a leading operator of marine transportation between mainland California and Santa Catalina Island, carrying over 33 million passengers across its multi-vessel fleet. Most of its ships are already powered by mtu engines. The LA MER project is part of California Climate Investments, a statewide program funded through Cap-and-Trade to cut greenhouse gas emissions, boost economic growth, and improve air quality—especially in underserved communities.
