have blue
but still ... 5 hp drag on the boat. that is a lot.
The was with a 47 foot, 20,000 pound catamaran doing over 9 knots in a 20+ breeze, with two of the 12hp electric wheels. Your mileage may vary. "Martin Baxter" wrote in message ... Jeff Morris wrote: Being a little sloppy with the units is not that bad - his real blunder is claiming 72 Watts output. The Condor catamaran claims 22 Amps at 144 Volts, or over 3 kW output when regenerating in a good breeze. They generate enough sailing during the day to power in and out of their inlet. I'm still pretty skeptical, 3 kW is neary 5 Hp, allowing for some losses it's going to be equivalent to stapping a 5 horse outboard to your bow and run it full throttle trying to push the boat back. This might have a significant impact on performance, speed wise, no? Cheers Marty |
