Calling all Electric drive sailboat owners

I'm very interested in electric drive sailboat setups but have seen only one first hand.
If anyone has access to an electric powered sailboat I would very much appreciate an chance to see your installation.

And yes I do know about the distance limitations of today's battery technology.
I liked the way one guy expressed it. He said his whole battery bank was the about the same as 2/3 of a gallon of gas.

But for some reason it is very appealing to me and would like to see a couple of actual installations in person.

Hi David,

I have a 1976 Ericson 27 with a SolidNav Explorer electric motor unit (company is out of business). You might try contacting Electric Yachts, QuieTorque Electrics | Electric Yacht ,for locations of installations in your area.

Re: Calling all Electric drive sailboat owners

How is it working for you?
What is your battery config, range?
What is your amp hour draw at whatever speeds you happen to know.

Hi David,

You might want to check out the Yahoo group http://groups.yahoo.com/group/electr...s/messages?o=1

To your questions;
It's working great and has been for over 4 years
I have two separate 48 volt banks for propulsion, 4 group 27's and 4 group 31's
Range - I've motored for 7 hours at 4 knots and used most of one bank
At 4 knots amp draw is 20 amps, at 6 knots amp draw is 110ish

Re: Calling all Electric drive sailboat owners

I just finished installing a 5.5 kW system from Propulsion Marine in my 1976 Ranger 33 that I keep near Burlington, VT. At this stage it works well but I need to permanently mount the components and do some watts-to-knots testing. Instead, I've only used it for maneuvering around the mooring and because of its ability to spin very slowly and the big new prop, it is much better at that than the old A4 and small prop.

The batteries are four Trojan AGM group 24. They probably have only a few miles range, but as I said I haven't tested.

They are charged by two Sanyo 195 W PV panel on a bimini frame. These are excessive, but the price was right and I couldn't find smaller ones that could charge 48v without getting too low wattage.

There are lots of good reasons!
