    i have a secret,,hehe,, i know a couple dudes who are about to come out with a kit for this.electric motor batteries, and a new way of charging them batteries without the sun.
    prices will start round $500.00.. its a whole new way of looking at electric motors for the small and midsize sail boats.. hehe ;)

    That sounds like great information. Can you steer us in the right direction so we know where to look for this new product/technology? Thanks, Jack

    they are getting there patent in a few weeks, or should i say applying for it. i cant say much cause they asked me not to, but if you stay in contact with me i will scream the minute they say go. i have looked it over, and wow, i think its gonna be one of the biggest things to hit the boating world as the first oar lol ;)
    i am allowed to start a list for my friends to be put on as the first people to be able to get this product after they see it and see the results. so anyone wanting a first look and wanting after that anything else can message me. and i will be sure you know its available before all else has a chance. ;)

    As soon as it is out let me know, or better yet have them post a systems explanation. I know a lot of people here are interested in this type of system, but havent seen anything worth buying yet.

    I hope it doesn't turn out to use snake oil as a lubricant!

    I think using the heavy bats as keel ballast is the key here.

    Just got to design a nice way to store 1/3-1/2 of boat's weight in a shoal draft keel in batteries.

    Bats like to come in every changing array of shapes and sizes, so use sheets of lead to fill in gaps.

    Yes, there are a few issues with possible flooding and venting, but nothing too 'deal breaking' IMO.

    Two basic ways, as I see it.

    1)top loading single piece 'part of the boat' keel/bat-pack

    2)sealed detachable keel/bat-pack with only plus and minus cables coming out. It would take a haul out to service bats, or some 'drop pod and recover pod' operation.

    I'd go with top loading 2.2 volt cells wired in series with two cables coming out.

    The ones I've worked with are about 140 pounds each.

    what about a wind generator and freewheel charging off the elec motor.

    electric generated from your (one-lung-diesel)... Oh how the wheels turn.... Right back to the start position...

    "i was cruising back to the mooring today listening to that bloody awfull 1 lung diesel, i was thinking how nice electric must be."

    For a mile or two perhaps , but then its break out the oars!

    Electric propulsion seems best on model boats, or cruise ships.

    moisez ,

    I just reread your original post.

    If you're considering the "keel/bat pack" idea, then the tall cells I'm referring to would be great. You could run five of them in series (11 volts) to an over-sized, inboard 12-volt motor, getting lower RPM's but not loosing any torque. Less heat loss and forget about the expensive, vulnerable speed controller, just reverse/off/forward. The prop could free wheel while under sail providing you get a non-cogging motor.

    You could leave your solar panel(s) out 24/7 with a small, inexpensive charge controller/monitor to prevent over charging. It would also provide a low battery cutout to prevent over draining your battery. However, a digital volt meter should be observed to avoid this situation as you're suddenly without power which can be most unpleasant...

    Fuse each cell with a terminal post fuse. That way you don't need any inline fuses and it's safer.
