Torqeedo, who will exhibit at this year’s Electric & Hybrid Marine World Expo, has supplied an integrated electric propulsion system for the world’s first full-size solar-electric sewage pump-out boat.
The 25-ft aluminum boat was built to provide free sewage pump-out service for boats, preventing the discharge of untreated human waste into the area’s waterways.
The propulsion system for the boat was designed for the East Shore District Health Department by Pilot’s Point Marina in Westbrook, Connecticut, USA, and consists of two Torqeedo Cruise 4.0 outboard motors, four Torqeedo Power 48 lithium-ion batteries and four chargers, as well as a cockpit control panel that gives the operator an at-a-glance view of system status, including range at current speed.
The motors are driven by electricity from the batteries, which are recharged by eight 100W solar panels, providing 400W to each battery bank. The batteries also drive the boat’s 48V 2hp pump and provide enough reserve capacity for a full day’s work.
“This new solar-electric vessel will set the standard for future pump-out boats in coastal communities worldwide,” said Steve Trkla, president of Torqeedo Inc. “It’s a clean, green, zero-fuel, zero-emission solution with long life, low maintenance and minimal operating costs.”
