My main reason for two separate banks is redundancy. I came to sailing through aviation (hang gliding) and have grown to respect redundancy. I also thought, to extend range it would be nice to be able to charge one bank with a portable generator while using the other bank for propulsion. In real life (so far) I've never had to do that.

I understand the Peurket Effect dictates a bigger bank will provide more available amp hours but from what I have read at the rate of current draw that I use it's not that big of a factor. In the past I have had an issue with a battery that started to go bad in one bank and while I sorted that out I had a good bank to keep me sailing.

The PakTrakr monitor does give me amp draw among other helpful information to keep my batteries healthy (that's how I found the weakening battery). You are right that knowing amp draw is absolutely necessary. The most I have seen as far as regeneration is concerned is 4 amps at 48 volts.

I have a tight slip that gets some significant surge at times and having my boat walk to starboard is helpful. That said I will be installing the CS at some point.

Thanks for your interest, Mark

Tom,

Are you talking about this thread?

Tohastsu - 8hp 4cycle - tech questions

If so, those posts are by Larry and Susan MacDonald, not Lin and Larry Pardey.

Or were you talking about another post? If the Pardeys are using an outboard as an auxiliary these days, I'd be interested to read about it. (Sincerely not sarcastically.)

If a dirty bottom slows you down what do you think it does to your boat

It would be worldwide news if Lin and Larry put an engine on Taleisin!

Hey Tom,

Not sure if you were talking to me. I'll try to upload some pics of my real world oar installs. Very, very non-electric.

More pics of my boat at:

Macha, 6/1/08 - Lyons Imaging :: Our Galleries

To the other guy, those pics of Desolation Sound look beautiful. Again, I'll say that your boat philosophy depends on your priorities. If your deal is you want to cruise when there's no wind, then a motorsailor might be the best bet.

Why is it that we think "motorsailor" is an insult? It just is what it is, right?

My boat's builder and previous owner sailed her down the coast from Bellingham to San Francisco, where I bought her. He had sailed engineless up around Puget Sound, Gulf Islands, etc.

Down here we're blessed with really good afternoon thermals in the summer -- 20 to 25 knots pretty much every afternoon, so that definitely makes it easier to get around without an engine. Even in flukey areas and flukey seasons, it's possible to make it work -- but it does take patience and hard work.

Cheers,

- Ari

Re: Electric Propulsion - solidnav.com

I know this is an old thread, but was hoping some SolidNav owners might be still following the thread.

I have all but the motor and relay for a SolidNav 5KW motor. I upgraded my unit to a Electric Yacht controller and display set up.

So, if you know of anyone who has a bad controller, I have good one for a reasonable price.
You could also use this setup for a DIY electric motor set up, just need a motor and 48v relay.


I'm also selling my complete 5kw Electric Yacht motor set up. Comes with everything you need. I'm selling the unit because I bought the boat with the electric already installed and an outboard too. I don't need both, and I do long trips vs short day sailing that require many hours of motoring. I do sail when I can, have enjoyed the electric for maneuvering in the harbor or just out for a day sail.
The Electric Yacht complete unit with 4 (100amp)batteries and charger would be $6000, asking 1/2 price, $3000 OBO
I have complete description and pics here:
