a watt total system, It would set you back about 14 to 18 thousand for
a 6000 watt system. You would need another $5000 to $6000 for the
electric motors and controllers. In terms of a marine repower that not
an outrageous number. A good 6000 watt generator installed would not
be a lot cheaper then the solar array and you would still need to buy
gas!
Your other options would be a hybrid electric Both www.ossapowerlite.
and http://www.steyr-
expensive You needing a twin screw.
Your looking a $20,000 a screw.
And with all the above you still need batteries. But again these are
not outrageous number for a marine repower in boats this size! 50
foot boat just cost more to repower then a tiny 30 foot boat.
But then you have to compare this to the running cost of the gas
motors you have now. Everything above would cost less to run per
mile. The question becomes will you put enough miles on your house
boat to recoup the cost? If your planing on doing the great loop at
low speeds maybe.
