Do the math. 48V, 106A, 3 phase AC can make ~12bhp.
Three phase batteries is it now?

.................... Being different is cool!
Recharging the batteries pretty much defeats the purpose of an electric powered boat, doesn't it?

I meant to say "Recharging the batteries with a generator pretty much defeats the purpose of an electric powered boat, doesn't it?"Don't see how. Joan's intended use as she described it sounds to me to be very well matched to a battery solution.

I thought the purpose was to silently sneak up on water fowl!
It can be practical to run batts/elec propulsion with a gennie to charge. If 90% of trips are within batt range, then 90% involve NO running of the gen. That works fine. Gennie helps out on the remaining 10% of trips.
The key parameter is what are the durations of expected trips? If running all day in the ditch or bay or offshore, no good.
This thread is like the Energizer Bunny! It goes on and on...
(Someone said earlier to see the humor! So there it is...)
Starside,
I came across this article today and thought of your project.
The Log Newspaper | California Boating & Fishing News - NHYC-refits-its-shore-boat-with-electric-motor
“The beauty of the engine is it’s burning no fuel, it’s no longer diesel and completely electric and probably saves us $5,000 a year in fuel,” .......
while they may save $5K in fuel, they will see at least that increase in their electric bill.
Hardly. On a Duffy, it cost around $1 in electricity to cruise all day. .......
No doubt but you can only cruise two hours.
I personally think electric boats are the future of boating. In other countries, they are much more popular. Even here on the Chesapeake, you see Duffy boats everywhere.
Different strokes for different folks. No disrespect intended.

Wrong again. Duffy has sold more than 10,000 electric boats and there is a constant demand for them that Lear of the Learjet family is trying to compete with a line of their own plug-in boats. If Duffy offered a diesel or gas versions, I don't think it will be as popular. Imagine cruising a Duffy without the benefit of no engine noise, no vibration and no exhaust - that just defeats the purpose of owning one.
I understand that there is substantial savings in running an electric boat but I don't think Duffy owners care about that. Be open minded, rent one and you'll understand.
I don't see charging stations along the ICW.
