Dead Boat Electronics - Need Some Advice

While fishing on friday, my electronics went dead. No radio, no Lowrance, no nav lights, no bilge pump. Power coming into the radio is separate from the power coming into the rest of the electronics. I messed around with the Perko switch and it seemed to be functioning fine. The boat would start right up after turning it off. No fuses are blown.

Anyone ever had an issue where the Perko would supply power to the engine but not the rest of the accessories? I got a D in circuits back in college and I'm just as confused now.
