Innovative Electric tugboats


Electric tugs - a significant improvement. 
5.3MWhr batteries
5:57 1/10 the noise of diesel-powered 
3:13 designed in Vancouver BC
8:37 not useful in locations needing 10 dockings a day (presumably because of charging down-time) 
4:11 Motors are mounted vertically, perhaps to make it easier to rotate the direction of the propellers.
6:53 Used in Kittimat Bay guiding ships 159 miles (longest navigation channel in the world) along a narrow inlet to a hydroelectric-powered aluminum smelter. (https://youtu.be/LBDQf5t3rlc?si=Ak1e-4coq1-qHSBa)
