Okay, so I've looked more into the stats based on their marketing material, and I just don't see how the math works out...
They're claiming a 200kWh battery which seems a bit high for the size of the boat.
An equivalent battery system for marine environments that exists today is the Deep Blue BMW i3 (https://www.torqeedo.com/us/en-us/technology-and-environment/battery-technology.html https://www.torqeedo.com/us/en-us/technology-and-environment...) which is a Torqeedo-BMW collaboration. That battery is 40kWh and 278kg.
Now, obviously there is a BMS and other parts that don't need to be replicated 5x, but scaling that up to a 200kWh pack gives 1390kg. That is absolutely ridiculous. Candela's entire C-7 boat weighs 1300kg, and it's only able to maintain a good range by utilizing hydroplaning extensively.
I'm not sure how a conventional planing hull that might weigh well over 2000kg with interior components, passengers, etc will get any reasonable range, and I suspect they don't show average range or loaded weight in the stats because it just doesn't look great compared to their competitors.
