I have a 20 foot catamaran. Obviously, it has no electronics system. This spring I wanted to install a VHF radio and possibly a small stereo system. Obviously, I will need some sort of power source. I'm thinking a battery.

Questions:

-About how much power will I need to last an 8 hour day? I want a fixed mount 25 watt VHF.
-Any suggestions on a battery that is as lightweight as possible? I mean under 20 pounds.
-Would there be any realistic way to charge the battery while out on the water?

Thanks!
