I am startng to agree with you... just a bit lighter and just too expensive......

Suggest you check out the Odyssey batteries for your application. They are what Nigel Calder has chosen for his new electric/hybrid that is currently being built. His full explanation of the technology can be found here:

I think you will find the article on "Breakthrough Battery Technology" interesting.

I honestly think that some of the resistance to electric drive is that it is an admission that the " big cruise" is not going to happen. Many sailors have such aspirations and it adds to the enjoyment of boating.. that you might escape to the South Pacific one day.. but having a 50 mile motoring range kills the dream...
I think you make a valid point here. I would appreciate it if you post regularly, as I am very interested in converting my boat to an electric drive in the forseeable future. It would be nice to have the benefit of your real-life experiences.

Not sure if you are aware of these but they should be a serious energy option fairly soon:

Thanks !! Yes I am very much aware of the fuel cells. I have a beach house that is all solar powered, so I looked into them as back up power.

Sailormann-

Fuel cells are a great idea...but you still need to feed them. I'd take the Marine Fell Cell Max Power website more seriously if it didn't have serious grammatical and typographical errors.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Trolling Motor and Inboard Electric

Earlier in the thread was a link "cheaper solution" which used a trolling motor. About 4 years ago my wife and I modeled a similar solution for our Catalina 25 to replace the Seagull. We used a 36 volt 110# thrust (largest available) transom mount salt water trolling motor. It is connected to 3 D31 batteries from Sams Club. The batteries are mounted on the centerline under the quarter berth. The slip has power so we just plug up the charger when we are through sailing.

This setup has been fantastic for our type of sailing. We sail on an inland lake (no current) and the distance from our slip to open water is about 150 yards. We are out there to sail not to motor extended distances.

The boat is by no means fast but nothing about a Catalina 25 is fast.

What is remarkable about the setup is the ability to stop the boat on a dime and know without a doubt that the motor will not konk out. The other unique ability is the turning radius. Our motor is not coupled with the tiller so we can crank the motor around perpendicular to the long axis of the hull and spin the boat around the keel. Not very usefull out in the open water but when manuvering in tight quarters it is great.

I have researched inboard electric systems for larger boats as well and have really been impressed with the products from electricyacht.com. I don't think they were mentioned in the thread.

Side note - anyone working with DC power please be aware that a bank of 12 volt batteries wired to provide 36 volts (or 48 volts, etc.) can put out a lot of power. We had a short during instalation which melted some pretty heavy wiring, pitted a large screwdriver, and blackeded the fiberglass. I don't know how dangerous it actually is but I treat it with equal or greater respect than 110 so as not to find out.

I have been looking into the electric yacht drives and they look very good Here is an example in a heavyCal 40 There are other examples of installations at this site.
