All American Marine has constructed and launched a 150-passenger hybrid electric vessel for Kitsap Transit.
The aluminium catamaran – Waterman – was designed by Washington-based Glosten and will operate during peak times on Kitsap’s Bremerton-Port Orchard or Bremerton-Annapolis routes.
The 21 m x 8 m USCG-certified passenger ferry features an efficient aluminium catamaran hull, ADA access throughout the main deck and twin BAE Systems HybriDrive propulsion systems driving fixed pitch propellers. The HybriDrive propulsion system includes a generator, propulsion power converter, house load power supply and control system.
“The hybrid system is fully automated, assessing the power loads, both hotel and propulsion loads and manages the entire system,” said All American Marines’ president and chief executive Matt Mullett.
BAE Systems’ HybriGen system requires lower engine operating hours and is more streamlined than a conventional drive, requiring fewer parts, thus resulting in savings in both fuel consumption and maintenance costs. The vessel will also operate nearly silent while under battery power when passengers are loading and unloading.
All American Marine said this will be the first hybrid-electric passenger ferry in Puget Sound and is a clear sign of environmental stewardship. A statement explained that the Glosten team worked closely with Kitsap Transit to create a ferry customised for Sinclair Inlet, but flexible enough to meet future needs.
It added “Passenger comforts were of particular importance to this design and include a variety of passenger spaces with lots of natural light, a unique ADA-accessible bow, and a spacious passenger cabin and sun deck.”
“We are proud to build advanced hybrid-electric vessels, such as Waterman and work with visionary partners, such as Kitsap Transit, Glosten and BAE Systems to develop and construct the boat of the future," Mr Mullett said. "All American is at the forefront of the decarbonisation movement in the maritime industry, and the lithium-ion hybrid electric propulsion system on Waterman is another example of our progress.”
