No comments from the very opinionated crowd? Are ye old farts alive?

[Beckytek]

This old fart (74) is still alive, (just barely). Not looking for anything new and fancy, just trying to keep what I have running. That's enough for me. Ron

This would clearly NOT work well for our needs. It says it produces 210 kilowats...so assume a 10% loss of energy (very conservative) from converting diesel into electricity...you'd need a 231 kilowat genset jsut to run ONE of them. My previous boat had a small get-home electric motor tied to the genset. It was truely a get home motor, designed to get the boat up to 4 knots on FLAT water with no wind or current. It was a package available from the manufactuerer...get home motor and an upgraded genset to run it...and it needed a 20kw genset.

As far as the battery propulsion idea...even the little 9hp version draws 70-90 AMPS at 2/3 throttle...you'd deplete a house bank mighty fast. The claim that the cat can run indefinitely with two of them with wind generators and solar cells...I call BS unless they throttle back to 2-3 knots. Two of them running at the aforementioned 2/3 throttle would draw 140-190 amps...show me a cruising wind generator or solar panel array that can produce that kind of power...I dare ya...it sim,ply doesn't exist. I wish it did...if I could find a way to cruise "indefinitely" at even 4-5 knots in my boat...I'd be on of the first to sign up.
