Hi
Have a look at Bellman/Mastervolt.

Probably to pricy for you, like most of us normal mortals, but worth a look
to see the specs and how they set up diesel electric pod systems. Every
thing from 2.5kW to thousands of kW.

Subject: [Electric Boats] Getting Started - Diesel/Electric System for
Catamaran - Newbie
Hi Everyone,
I was wondering if I could get some basic help and pointers on setting up a
diesel/electric boat.
I have a 45' catamaran (I'm building right now) with 18,000lbs max
displacement. It's a non-planing sailing catamaran capable of 20 knots
under sail in a very stiff breeze.
I do charters, so I have large house loads to contend with. This means that
a diesel/electric system might save me weight and money over having twin
engines, plus generator, plus solar, plus LPG system for cooking, plus
heating system etc... etc...
I need some help though, because the electric stuff is new to me.
The basic requirements are as follows:
*30HP (20kw?) thrust for each hull
*Pod type electric motors (one for each hull) running from a main battery
bank, no need for pods to rotate - I have rudders
*60HP?? 45KW?? DC Generator to charge battery bank and provide for house
loads.
*Some appropriate type of battery to store power - a lot of power. Lots of
cycles and quick charging. Ideas?
*Throttle/controller for drives, similar to Morse controls.
*Large inverter to support electric oven and/or electric heat and air
conditioning house loads.
*Automatic control system to kick on the generator when the batteries get
low and/or when the main drive motors are engaged.
Any ideas on where to start with the design of this propulsion system?
Basic technologies to look at? Where to source the equipment? Specific
things to look out for? Where to read for more information and to get my
understanding of this type of system to a higher level?
Thanks in advance for any input.
