Jim, can you say a little more about whatever experience Nordhavn has with
the relative efficiency of gen sets vs. big alternators? Is there any
quantitative data you can share that outlines why "an alternator may take as
much as three times the power (fuel) to produce electricity than a
generator"?

it takes precedence.

Dave, what is your reasoning for having potentially erratic shore power run
direct to your inverter rather than to a (cheaper?) charger? Your excellent
explanation in recent posts for why you like to draw off your batteries
rather than a gen set (varying loads will always get enough juice from the
batteries) would seem to apply to oftentimes limited or unreliable shore
power. And wouldn't using a shore-to-charger-to-battery-to-inverter system
let you use European shore power without a lot of appliance conversions?
