I don't understand WHY anyone would drag windmill in the water? If you're sailing, you've got enough wind to spin it right? If you're motoring then you've got an alternator spinning right? What am I missing here?
I like the idea of a propshaft mounted alternator, especially for larger boats. It seems simple and logical.
However, it seems that a wind generator is a lot more versatile and just as, if not more, efficient than the propshaft mounted alternator arrangement. In addition to being more versatile since it works on the hook (assuming there is wind) as well as at sea. I understand needing solar and wind, or solar and propshaft alternator, but WHY would anyone need both a Wind Gen and Water Gen?
I'm very confused...

The concept of a combined wind- and water generator is
also use by the duo-gen.
http://www.rietpol.nl/duogen.htm
It's a dutch site but the pictures suffice...
I won't install it cause I have this gantry mounted on
my pushpit. I'll install an Air-X Marine instead on
top of the gantry.
When you install solar panels be aware of the up to
30% higher efficiency you can achieve with a
MPPT-charger.
It's electronics makes proper use of the 17 volts the
panels provide and does not simply cut away the
"superfluous" 2,5 volts.
I'll need a lot of solar panels to keep up with a
fridge and a freezer. I know, I can do without but my
wife and I like it too much. After filling up the roof
of the decksaloon and the bimini I'm thinking of
"pivoting away" four panels in the searailing and
turning them towards the sun (with a variable angle)
when on anchor.
