Re: running Wind Gen on the Hard
You could overcharge the battery.
You are putting wear and tear on the wind gen.
You run the risk or the wind gen breaking a blade or ?? and maybe even a bit of liability for neighboring boats and /or people.
And I dunno, does it make it more attractive for theft?
Possible electrical fire
If the batts die over winter that could be a HUGE expense.
And a lot of those 'risks' are very slight, just depends on your own comfort level I guess.
