Trondheim Trawlers are developing the electric trawlers called the Trondheim 40
The 40-ft (12-m) vessel will feature two Torqeedo brand Deep Blue i 1,400-rpm electric motors, which will be powered by two battery packs. One charge of those batteries should reportedly be good for six hours of cruising.
Needless to say, though, fishing expeditions can last longer than six hours. For that reason, there will also be two Torqeedo diesel-powered generators on board. These will produce electricity both to run the motors, and to recharge the batteries.
