Hi Jim,
I converted a 30' '78 Hunter, and sail SF bay. Details here:
https://sites.google.com/site/electricboating/Solar is pretty much a waste of money unless you can cover every square inch of your deck (otoh, you can probably go off-grid with a wind-genny in our area - I did the math once, and if you go out 1/week it works).
Pay close attention to the section on tides :) It's like the Marines..."No better friend; no greater enemy"

(p.s. PM me if you want to go out some time and see what it's like)

I read the article in the June 2011 Good Old Boat where Joe Steinberger converted a Tripp/Lentsch 29 to an e-drive, and he provides a list of components and suppliers, but, he didn't go into any detail about how the components were chosen, what trade-offs he made, where he obtained details and specs for the components and how to hook them together, or how to evaluate other options.

I'm an ocean engineer and computer scientist, so, I'm quite capable of understanding the technical details, and could design and install a system from scratch, given enough time with a McMaster-Carr catalog. However, I was hoping to come up with a variation of something someone else already has working for a sailboat similar in size to mine, and to replace an in-board engine.

I'll only need a minute, or so, of drive time to get between my slip and the channel, and occasionally, I may need up to 20 minutes of drive time if the wind is coming directly down the channel and I don't feel like tacking every 30 seconds.

Are there significantly different options from the components listed in Steinberger's article, or is that a reasonable-enough solution that I can just go with it? Here's what he used:
