"It's not a sustainable system, high voltage is very dangerous. If there are 4 water circulation motors in the boat and there is still sea water interaction, if it's not direct drive and requires a gearbox and cooling, if the battery has to reach high amps, if the battery charge and discharge balance has to be cooled at high temperatures, if the motor is heating up even though there is a gearbox, and if the motor also has to be cooled with seawater circulation, and even if there is a special cooling fluid for the battery, and if I have to use service batteries to cool 4 separate circulation motors and circulation water instead of using them for my refrigerator, and if my top speed range is only 39 minutes, and if I have to charge with 380V three-phase, or if I have to wait 9 hours to charge with single-phase, and if I have to spend 39 minutes cruising and 540 minutes charging, if I have to pay 7,000-10,000 euros for a 380V 90-100 amp charger and reduce my charging time to 2 hours, if I'm going to halve or even more reduce my battery life by fast charging, and if I can't feed my battery from any regenerative source, and if I can't provide feedback energy from the natural rotation of my propeller due to wind or current like wind or solar, unfortunately XSHORE boats are NOT REALLY SUSTAINABLE. Thanks."
