But a small generator would do it.

Know of any small 12 volt only gen sets?
(I think the manufacturers are missing a niche here)

I don't know about back there but they are fairly common here. I think
that most of them are actually 220 VAC generators with a rectified
circuit but they do charge batteries.

There are scads of those kind on the market.
But even the small ones are pretty fair sized - and pricey.
There is no real technical reason one couldn't make a 12 volt gas powered
charger no bigger than a weed-whacker motor.
(BTW, the 4 stroke versions are pretty quiet)



If you got a spare quid you might look into solar panels. I somehow
get the impression that most of your sailing is a week-end sort of
thing and a solar panel, or two, would certainly keep your batteries
charged.... as long as the sun shines.

That's true for now.
The marina has AC power, so keeping batteries topped off is no problem.
But a couple of days out of the marina gets to be a challenge.

I've converted most of the lights to LEDs.

The real current hogs are the pumps.
Like the pressure water system and wash down pump.

I have a couple of solar panels - 5 and 15 watts.
But I'm not quite sure how to work them with the existing battery charger.



Cheers,
