Glosten completes design of hybrid passenger-only ferry

JUNE 26, 2017 — Seattle-based naval architecture and marine engineering consultancy Glosten has completed the design of a 70 ft, 150-passenger-only hybrid ferry for Kitsap Transit, a public transportation agency based in Bremerton, WA.

"Glosten has designed a modern and efficient passenger vessel that will meet the demands of our riders," said Kitsap Transit Executive Director John Clauson. "As a public agency, at the end of the day, it's all about the people. We are confident that this new addition to our fleet will serve the people of the Puget Sound region for many years to come."

The Glosten team worked closely with Kitsap Transit to create a ferry customized for Sinclair Inlet, but flexible enough to meet future needs.

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.

The vessel features an efficient aluminum catamaran hull, ADA access throughout the main deck, and two BAE Systems HybriDrive propulsion systems driving fixed-pitch propellers.

"Outfitted with a battery-diesel hybrid propulsion system, the vessel will operate like a Prius – no more diesel exhaust and noise while passengers load and unload," said Glosten Project Manager and Design Lead William Moon, PE.

The new hybrid electric passenger ferry is the first in Puget Sound. It will be constructed by shipbuilder All American Marine at its Bellingham, WA, shipyard.

It is expected to carry over 350,000 passengers annually.
