Are you wanting to running off the generator or just charging? You will need a 10KW generator for the power you are talking about. What this means is while you are topping off your batteries you will be wasting fuel. Looking at Hybrids the idea is ICE sized for cruising speed not full speed, and filling in high power requirements with stored energy, or more likely the other way around. Consider using Honda and Toyota for a case study in there use of power sources.
I am working on a lower power, silent power source that should be idea in our application, but am not ready to unvale the product yet. It will be scalable in both voltage and power output. I don't see configuring anything close to 200 amps though.

Leese-Neville makes a nice series of alternators. I saw a 24v, 100a unit paired with a Lombardini one lung 5hp diesel in a 35' sailboat years ago.

Subject: [Electric Boats] Charging Question
Hi to all, I tried sending this message earlier but it seems to have got lost (or more likely I screwed up). I'm another new member and also interested in the over 30' solutions. One question I have for the more knowledgable out there is how you propose charging your batteries away from the grid. In this size range it seems ever more important to have some sort of generator aboard. In previous posts people have recommended connecting a PM motor to a small diesel, which is essentially what I would like to do. How would you go about regulating this set up when charging batteries, is there an off the shelf device that will handle the voltage and amps (I'm looking at 48 or 72v and up to 200amps)?. Could the charging be controlled manually by adjusting output voltage and amps (with engine revs and a controller?) .
Anyway thanks for any help you can provide.
Colin.
