Brian-
You could get a look at my electric conversion sometime---just downstream from you just below Vancouver at Caterpillar Island on the Columbia.
Mine's a converted outboard unit with up to 6 electric HP available from a single string 36v golf cart batteries. My prop is a 12x12x3 brass spinning inside a 14" prop guard. Mine is 26ft LOA and about 19' LWL with about 3500# overall weight I'd guess at this point. Assuming your boat could run similar to mine----6knots with 6HP, 5knots with 3HP, 4knots with 1.5HP, 3knots with 650w or so, you can see that the range you'd have depends on speed. With an inboard setup, you would likely want a reduction assembly unless going to something like the brushless AMeP motors, which may have a model out now that is rated 5HP steady. As for regen, there are a lot of opinions out there---it's doable, but the benefits vary and depend on your usage. If you want regen, you're best off buying a controller that has that built in. Figure that, at best, with a setup that absorbs 6HP electric power max, in generation mode, you'll be hard pressed to get more than 1HP worth of electric power out---likely far less unless the wind is really pushing you hard.
Here's pics of my boat: www.evalbum.com/492
Email me offline and we can get you out on my boat sometime for a quick spin.

Subject: [Electric Boats] Golf cart parts for sailboat
Hello All,
Brand new to the group, and please forgive me if this thread has been talked about(and I'm sure it has). I have a Cascade 29 that is currently powered with a 12 Farryman, single cylynder (very annoying). With the 33 gallon fuel tank and the engine/trans assembly gone I would have a tremendous amout of room for banks/motor/controller.
Would a typical golf cart 36v or 48v set up work or would I still need a reduction assy? Will these set ups re-gen? I have shore power available for charge, as well as a 2KW gas genny. I could easily add wind/solar. No off-shore work. No extended motoring periods (Columbia river) Also I'm not sure how long a typical golf cart batt bank lasts. The boat is easily run up to hull speed with the farryman and a 12x 8, dbl bladed prop (could probably fit 13").
Obviously, on a budget with the current state of things. Any help getting me pointed in the right direction would be appreciated.
