[Electric Boats] Electric speedboat revisited

 


Donor: Glastron v174 Bayflite
Length: 5,30 m
Beam: 2,20 m
Weight: 850,00 kg

coming out:
Volvo B20 130 HP 350 lb/ 160 kg
Gastank (80 L.) 220 lb / 100 kg
Ballast (in bow) 110 lb / 50 kg

total 680 lb / 310 kg

Going in:
Kostov 11" 192HV 178 lb / 81 kg
60*100Ah LiFePo4 462 lb / 210 kg
Soliton1 controller n/a

total 640 lb / 291 kg

Though I admit the range will be limited, I feel the performance should match or exceed the original ICE setup. Including some other components the parts investment would be about 15.000 Euros. Not cheap, but interesting to note that a full tank runs at 150 Euros; depending on usage there could be a cost/benefit down the line (but this is not the point of the conversion)

The boat would be used in and around the canals of Amsterdam, so mostly slow speed cruising (as enforced by our friendly waterpolice).
When the situation allows: WOT!

Q: The parts I will be using are not specified for marine use, pitfalls?
Q: Though the Kostov has more or les the same RPM range as the ICE, I feel the prop should make more of the low end torque, design suggestions?

And of course any other ideas & suggestions are welcome. If there is interest I will update with more information.

Happy Boating!
