I bought a 24' sloop over a year ago and I am considering getting rid off all the wires. All I really have are Running lights,Cabin lights,motor light and a dept finder that only works half the time. I sail in the chesapeake bay so I was thinking about using battery clamp down lights and lanterns in the cabin. This would cost me less then a new marine battery not to mention some of the wires are house wires. Another option I am trying to figure out is using a 9 volt with a switch.
