Hello and thank you for your time.
I'm considering a sailboat which is on the market with the following system:
Yacht 10kw 48volt engine
with hydro generator
that produces up to 120 watts of charging
while under way. 2x Blue Sea solar panels
, 48 volt quick charge, 12 volt Intelipower charger
Solarburst 3024I, 4kw Champion Generator
the battery storage
is not disclosed, but I see it would have to be significant for any off shore passage
. I assume that the battery charging
would occur under sail. “5 knots of boat speed will give you 40 watts of charge and 7 Knots will give you a whopping120 watts.”
I also assume that there would be significant drag on the boat with the prop powering a generator.
If this system works, I have my hat off to the owner and his forward thinking including a composting head
Please note that I much prefer to sail and might even tolerate a day or two becalmed rather than motor
. However, I can't judge the practicality of the above arrangement for moving about in a harbor. The boat displaces about 7 1/2 tons.
Thank you so much for any advice.
