[Public-List] Electric power.

[Richard Mair]

The generator is stowed in the starbord locker which I am in the process of
sealing off from the bilge and it vents overboard. Fuel same locker 3 cans
5 lit each
I run it strapped down beaside the lazarette and the fumes go to the stern.
It plugs into the normal shore power.
Have 2 solar panels mounted on hollow pipe between the srern pushpit and
the stanction. 90 watts total running through a step up converter to keep
the traction packs topped up. 1 panel 50 watts mounted ahead of the hatch
to charge the small house battery. This can also be charged from a 48/12
volt converter.
Will post trips later. I expect the upriver to be slow wirh lots of
charging stops
