Re: [Electric Boats] Why no high voltage?

Well, that answer made sense to me. We are looking at converting a 50' Hatteras to electric power and will need a pair of 50hp electric motors. The boat is currently powered with a pair of 8V71N Detroit diesels that drink 5 gal/hour each...at idle! Lol We travel at displacement speed or fractions thereof so much less actual power is needed.

Some folks are using HV systems.
Notwithstanding that, the driving reason why most use low voltage setups is:
·         Availability of reasonably low cost 6-8kw, 48v or less parts thanks to the golf cart industry
·         The fact that for many of us, 8kw of power is plenty
·         That weight in cabling and power lost and cost in cabling is not an issue

All current electric drive systems are based on low DC voltage systems. Why no high voltage systems, 110 or 220 volts? Currents can be much lower resulting in smaller wiring. Any ideas on this?
