The 65-foot ferries, Juliette Gordon Low II and Susie King Taylor II, are equipped with MJP UltraJet 305 waterjets and a serial hybrid propulsion system. This system integrates permanent magnet traction motors with BAE HybriGen® Power, supported by Cummins 6.7L Marine Diesel Engines and HDS 200 Integrated Starter Generators. The technology enhances power efficiency, reduces emissions, and minimizes environmental impact.
Designed for continuous operations on short routes, the ferries’ hybrid propulsion systems optimize energy use and provide reduced fuel consumption and emissions. The shallow draft and enhanced maneuverability of waterjets allow the vessels to adapt to varying tidal conditions and frequent docking requirements.
“Chatham Area Transit faced specific operational challenges, including frequent docking and varying currents. Waterjets, with their inherent maneuverability and seamless integration with hybrid-electric systems, provided the perfect answer,” said Kevin Kirby, President and Regional Director of Marine Jet Power Americas.
Derecktor Shipyards, a leader in hybrid vessel construction, leveraged its expertise to build the ferries. With four hybrid vessels launched in 2014, the company continues prioritizing sustainable solutions in marine construction.
“Building these hybrid waterjet ferries allowed us to apply our experience and strengthen our role in advancing sustainable maritime technology,” said Erik Derecktor, New Construction Commercial Manager for Derecktor Shipyards.
The partnership between CAT, MJP, and Derecktor demonstrates the potential of collaborative efforts to address environmental goals while meeting the operational needs of urban transit systems.
Derecktor Shipyards has launched several hybrid vessels in the United States, including:
The ferries are en route to Savannah and will begin passenger service in the coming weeks.
