They don't seem eager to reveal actual power or energy consumption. I
wonder why? The claim 300 amps peak, 170 amps continuous, and 30-50 amps
at "cruise speed". All meaningless because they also give a wide range
of operating voltages and don't say at what voltage all the other
ratings are measured.


yes, yes and yes...but it does look like a promising technology and one
that I'm actively considering...unless I have to stick a metric ton of
batteries under the cabin sole


Aye, there's the rub. I can see a setup such as the Glacier Bay
diesel/electric having some advantages over straight diesel
propulsion, but running just off of batteries isn't going to be very
practical for anything except short jaunts that involve returning to a
rather hefty land based charging system every few hours. Great for
local tour boats. Probably not so much for cruising situations.



According to the website, the cruise time varies between 2 and 10 hours. It
also said something about regeneration, but I can't seem to find it again.
That would extend the cruise time, perhaps indefinitely (sort of) depending
on efficiency of regeneration.
