hi everyone, im new to the forum.
i live in new zealand and i am about to start building a 35' sailing catamaran.
http://www.wallerdesign.com.au/cs35.html
simple deep v hulls 3600kg(8000lbs) displacement.
the boat is designed for petrol outboards but i am really not keen on this idea. have been in contact with the designer who says due to the deep v hulls twin diesel installation would not be ideal. he reccomended somehow using a single centrally mounted diesel powering 2 smaller drives. this led me to consider diesel-electric propulsion. (or hydraulic but from what ive read so far it is inferior to electric)
knowing little on the subject i have spend many hours reading many webpages but alot of things still dont make sense to me! i would have 10-12hp on each side if using diesels, would i need similar sized electric motors? i was at first thinking of modifying 2 outboards to run with electric motors in the designated positions but it sounds as if just having the electric motors inboard mounted in the hulls would be more efficient?
where i get most confused is it the many possible ways of doing things.. i am on a budget and do not want to spend more $ than i have to. the main reason for having electric drives is just to use a single engine.. i am not worried about having a long battery range or anything just decent efficiency and reliability. i would quite happily just run the motors straight off a generator and start it whenever i want to move.. what would i require for such a setup? is ac or dc the way to go? to be honest i still cant get my head around the difference!! what would be the best speed controller to use? props? as you can probably tell im pretty lost..
any help would be greatly appreciated! im keen to learn alot about it
thanks
adam.
