Bob, what an interesting project. The work you did on your eCat is quite impressive.
As in my message to you I’m interesting in adding electric drive to my 18 ft Hobie cat.
Then I found this. A diy electric foiling catamaran made from some Hobie 18 hulls. Mad skills by this builder who basically built it from scrap parts. Top speed of around 16 knots. Cruise speed of 12 knots at 5.8 kW. Power is from 24 kWh worth of Chevy bolt cells.

I don’t have the chops to do a foiler…but your setup has given me a great start point.
