if you go to youtube.com and enter "emotion hybrids" as a search you will run into several really informative whiteboard discussions of hybrids in general... this guy (Dave Tether) is all about catamarans and has a 47' Lagoon hybrid... there are little golden nuggets scattered all through these whiteboards... i've been plowing through info on the web for awhile now and think that this guy does the best job of laying it all out

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.
