Local ferries are speed sensitive, and unless ultra light and with hydrofoils, drag from speed will kill the feasibility of battery electric high speed ferrying

Local ferries are speed sensitive, and unless ultra light and with hydrofoils, drag from speed will kill the feasibility of battery electric high speed ferrying. If done anyways, you'd need almost MW scale charging infrastructure to make rapid round trips. Ferries often don't even tie to the dock, they just continuously push against the dock while passengers unload and reload, and turn around to resume travel.

> Local ferries are speed sensitive, and unless ultra light and with hydrofoils, How fast do you need to go to hydrofoil when you're carrying 200 cars? They're working on a battery elecrtric version of my local ferry, and yeah, it's gonna be a lot of charging infra; but in theory the operating costs are much lower, and the charging plans mean they increased grid redundancy for me, so that's nice. This is my current ferry: https://wsdot.com/ferries/vesselwatch/VesselDetail.aspx?vessel_id=32 https://wsdot.com/ferries/vesselwatch/VesselDetail.aspx?vess...
