Vessel Profile: It Takes a Village to Build a Hybrid-Electric Ferry

Seattle’s Elliott Bay Design Group shapes a new hybrid-electric, double-ended ferry for Casco Bay Lines of Maine. A 164-foot, double-ended hybrid-electric ferry from Seattle-based Elliott Bay Design Group (EBDG) was chosen by Casco Bay Lines (CBL) of Portland, Maine, to enter the construction phase at Senesco Marine of North Kingston, R.I., this fall. The new ferry is expected to enter service in 2024 to replace the existing Machigonne II diesel-powered ferry that operates between Portland and Peaks Island, Maine.

Shoebox Be Gone! Truckable Towboats Incoming

A new truckable tugboat collaboration between Tacoma-based aluminum commercial boatbuilder Silverback Marine and Seattle-based naval design firm Elliott Bay Design Group (EBDG) appears poised to disrupt the small tugboat niche. The 25' 10-7/8" overall length, trailer-able design has standard 500 horsepower, 12,500 pounds of bollard pull and a still water range of 60 nautical miles pushing about 10,000 pounds at 4.1 knots. The truckable tug is also compatible with electric, hybrid and outboard propulsion systems. “It’s been an exciting journey and we’re happy to have connected with Elliott Bay Design,” Silverback Marine founder and owner Ian Gracey said.

Hydrogen One:  A Maritime Milestone?

Hydrogen One: A Maritime Milestone?

Hydrogen One is on track to be the world’s first methanol-run hydrogen fuel cell working towboat. The world’s first methanol-fueled hydrogen towboat M/V Hydrogen One is on schedule for its 2023 splash. A non-disclosed builder has been chosen and initial steel cutting was on schedule for summer 2022. The prototype vessel features a shallow draft design suited for extended trips along its planned base of operations—the ditch between Houston and New Orleans with inland water capabilities. “The idea is to build it (Hydrogen One), get it fully operational, and put it through its paces before it goes to a customer…
