HYBRIDS the need for a reduction gear. The hybrid system will also incorporate battery power from two 80 kWh Lithiumion battery packs with Corvus Energy’s next generation Orca Energy batteries. Delivery is set for the spring of 2018.

Boats for CUNY, Harbor Harvest As we highlighted in our May 2017 issue (ML, May 2017, p. 32, “Humming Along”), The Science and Resilience Institute at Jamaica Bay, led by City University of New York’s Brooklyn College, has taken delivery of CUNY I, a new 65 ft long hybrid research vessel built by Derecktor Shipyard, Mamaroneck, NY. Derecktor Shipyard has already begun construction of its third hybrid vessel based on the same Incat Crowther designed aluminum catamaran hull. Plans for the new boat were revealed this past May at the Marine Log Tugs

& Barges 2017 Conference & Expo in Stamford, CT. Panelists Bob Kunkel, President of AMTECH as well as co-owner of Harbor Harvest (he knows how to butcher meat, too), Micah Tucker, General Manager of Derecktor Shipyard, and David Adamiak, BAE Systems HybriDrive provided details on the first of what could be a fleet of 12 organic market cargo delivery vessels. Kunkel, who has one of the most interesting bios you could ever read, discussed the development of an emissions-free waterborne transportation that would use a fleet of hybrid boats to deliver fresh farm products across Long Island Sound and down the Hudson River. One of the first stores to benefit from the “special delivery” would be Kunkel’s own Harbor Harvest organic store and deli in East Norwalk, CT. He’s already received requests from four Connecticut stores and

three Long Island Villages to open food hubs at their waterfronts. Designated as part of the Marine Highways Program, the Harbor Harvest vessel would be able to carry 12 metric tons of cargo (five metric tons of which would be refrigerated), picking up fresh farm and dairy products, meats and produce from farmer’s markets located near the water along the Sound. Kunkel says the route has already been proven and it would do what the Marine Highways Program was designed to do— take trucks off the road. In addition, the boat, once again using the BAE Systems HybriDrive propulsion and Corvus energy storage systems, would be able to operate for three hours without a recharge. Charging stations will also be located along the vessel’s trade route, which would provide zero emissions operation.

Torqeedo’s Plan to Electrify the Commercial Market

The leader in electric boat drives is quietly making moves. That was driven home earlier this year when Torqeedo Group hired Marcia Kull as its President. For years, Kull had been in the highly visible role of Vice President of Marine Sales at Volvo Penta Americas, where she lead the diesel engine manufacturer’s commercial and recreational sales effor ts in Nor th America. In her new role, Kull will be responsible for directing global sales and strategy for the electric marine propulsion provider. Torqeedo is a relatively young company. It was founded in 2005 but has already made a name for itself in the electric marine propulsion sector. Its lineup of products includes outboards, inboards, hybrid drives, batteries and sail drives. Its popular Deep Blue brand is of fered in outboard, inboard and hybrid drive models, with a power range of up to 80 hp equivalent. And its expanding its batter y development through a technical partnership with BMW.

So what attracted Kull to Torqeedo? As she puts it “Endless opportunities for innovation and growth.” Kull explains that electric mobility is increasing in popularity both on the recreational and commercial side. “As people are making their own environmental choices,” on how to operate their businesses, their fleet, “electric propulsion is clearly the way forward.” Electric propulsion has a multitude of advantages, according to Kull. It is far more efficient than spark and compression ignition engines—“You can be a smaller electric motor, and yet, get the same per formance…You also have all this power at really low rev/min. You get quiet operation, an absence of vibration, no exhaust or smells. “For an owner/operator the significant reduction in total cost of service will be the most telling,” Kull says. “Over the course of operation, we know the propulsion capital cost is dwarfed by the cost of fuel, lubricants, and maintenance over the useful life of a system. And that’s where an electrical system has a significant advantage. It’s immune to fuel prices. It never needs oil, and there are fewer moving parts that need to be removed or replaced.” Torqeedo’s lineup of products can be used in a variety of applications, including water taxis, riverboat cruises, and “heav y-dut y work.” That heav y-dut y work includes the use of an 80 hp Deep Blue inboard with a Schot tel drive,

batteries and chargers, on a 44 m hopper barge. The large gravel excavation barge is working in a quarry in Germany. Torqeedo also powered Europe’s first electric water taxi for Watertaxi Rotterdam. The boat is equipped with a Deep Blue inboard 80 hp and two DC generators. The combination makes the vessel 70% more fuel-efficient than the other vessels in the fleet. O n t h e r i ve r b o a t f r o n t , t w o of Torqeedo’s 80 hp equivalent Deep Blue Outboard drives are fitted onto The Queen Elizabeth Dr., along with independent battery banks. The 75 ft, 100% electric vessel, built for Ottawa Boat Cruise’s Rideau Canal Cruises, is the only one of its kind in North America. And soon, Torqeedo will power 44 river barges being built by Lake Assault Boats for the River Walk in San Antonio, TX. The boats, which will be delivered this fall, will be driven by a Torqeedo 10kW outboard elec tric motor with power supplied by batteries. The system will enable the boats to operate a 15-hour day before recharging. Innovation will continue to be the way for the company. A s Kull tells Marine Log, Torqeedo invests 100% of its R&D funds into actual R&D, ensuring that innovation and new product development is consis tently taking place— guaranteeing that Torqeedo’s future will be filled with, Kull exclaims, “Lots of growth!”
