Hi, I have no real hands on experience, but know some links that might be useful for you: http://www.oceanvolt.com/#oceanvolt-sea http://greenstarmarine.se/en/teknik/system/ http://img.nauticexpo.com/pdf/repository_ne/27158/leaflet-oz-marine-ab-2007-6768_2b.jpg They use Perm 132 -motor, I would personally chose DC, I think it is the most bullet-proof solution to use a DC motor instead of AC drives, if you have thunderstorms, saltwater and so on. they have a "regen" function when sailing, så if you fold out the propeller it will charge, if speed is enough. (I guess it is enough to just give it a "punch" with the motor to fold out the prop, and then then use contactors to reconfigure to a low speed low voltage "parallell" connection of the batteries, then you charge up the system when sailing) A cheap solution might be to find a scrapyard golfcart motor or similar? Not perfect and lower efficiency. But might be "free". If the use will be longer range I would go for a high efficiency PM motor, try to target the combination to over 88-92% at cruise speed and get longer run, possibly save some money on a smaller battery, lower amps and so on. http://www.thunderstruck-ev.com/electric-sailboat-kits-and-accessories-inboard-motor-ev.html http://www.agnimotors.com/home/index.php?option=com_content&task=view&id=5&Itemid=60 I am not sure if this unit in an USA company "kiwi prop" will provide charging when sailing as a normal folding propeller, I dont think so, but it was "cheap" and had an interesting design: http://www.kiwiprop.com/index.htm /John -------------- next part -------------- An HTML attachment was scrubbed...
