Ok thanks for the feedback.  I should have linked to the genset pdf for more info, here it is. http://www.polardcmarine.com/downloads/PDC-8340VP-40_brochure.pdf. It puts out 48 to 320VDC. The 12 or 24V refers to the regular alternator output for charging the starter battery.

That e-tech pod puts out 10kw if supplied with 48V or 15kw with 80V. I assume 72V would work too.

How fast do you think a combined 30kw would push the boat? I guess you could max out like that for about an hour with batteries plus genset, then power on via genset only. Then what is your estimate for speeds at 20kw with the 18" props at 1200 rpm? Probably faster than necessary but thinking more about power against headwinds in freezing spray.. and currents, at night.

The tube mount that Rob has devised will allow vertical raise/lower and have a tiller for 360 degree steering, mounted on the back of the cockpit bench. Not sure where the other pod will go yet.

I agree more solar is better, and there is plenty of space on the ww hull for 2kw. Was wondering how to string it all together. I guess thicker wires will do it. What brands/shop do you recommend for marine flexible panels these days?
