Arild,
Where you live ok.
>> snip<<<<
The Wife and I conserve gen set time by not boating in the summer. We stay
in our air-conditioned home. As I tell friends , yes the boat has a/c but
if I want to stay inside with the a/c on I can stay home a lot cheaper.
We just blt. our home and used top notch insulation all around , widows
etc. This only and I mean only lessens the amt of elec used to cool there
is no getting away from it, period.

If live-aboad boats were built to the same insulation standards as houses,
it would use a lot less energy.
I did not say you should do without A/C
What I said was there are ways to achieve comfort levels and using less
energy.
With proper attention to radiant heat rejection, insulation and window
films, the load on the air conditioner would be lessened. Instead of a
20,000 BTU unit you might only need a 16,000 BTU or instead of a 16,000 you
might only require a 12,500 BTU unit.
If you can reduce your shore power current draw from 30 amps to 25 amps
while maintaining creatuer comforts, that is a significant reduction. And
that is really the point I was trying to make.
Admittedly the Gulf area is perhaps the worst place for combined heat and
humidity.
However, not every list member boats there and some of the most vociferous
critiques I received were not from that area.
If I was building a boat for use in th eGulf ara i can assure you that
insulation, radiant heat shields and such would be as high on the priority
list as anything electrical.
And if I was considering a stock production boat, only those that would be
easy to upgrade would make the short list.
Ther are several ways to make the electric power system aboad much more
efficient.
Trouble is most people are not interested in even looking into ways and
means of doing that.
regards
Arild
