Yup. Depends on the marina. Not much typically. Get solar panels, then
you
won't have to charge the bats so often.

Definitely though of solar panels. And the idea I had was this: car
batteries are constantly kept cvharged by a belt driven alternator. Why
can't a shaft driven alternator do the same for boat batteries? And
powering the shaft? The wind/breeze via a small windmill type thingie.
Put it on at night. You'd probably have to build it yourself or have an
engineer design and build it - but have a windmill that connects and
thus turns a shaft in the column - the shaft goes down through the boat
to a a gear or belt which runs the alternator(s) - what do you think?

I think you'll not get enough current to do much beyond trickle charging,
but I don't know. Not my area.
