Re: Gauge of wires to use
The NEC rules for wire guages are the minimum Dia wire for the current so the insulation doesn't melt. Not what you really want for marine enviroment.
Without more information, (I'm assuming 12v devices). And not a very long run 16 guage should be plenty. For longer runs, it may be 20-30 ft from the battery to the panel, then another 10-20ft to the devices, 12 guage should be fine, (not for the current, but to minimise voltage drop).
To charge my cell phone I installed a car style 12 volt socket, and bought a car charger for my cell phone. For the phones that have usb style charger ports, I bought a 12v to usb charging adaptor.
I hope this helps. If you need more info, you need to give more details about the specific install you are doing. WHat kind of radio, what wattage etc... size of boat, distance from panel?
