On a 47 footer, the switch panel where they are connected now is bit of a run from the back of the cockpit, I'd say around 25'. I'm not sure that the load would necessitate it either, looks like I would have to use 12 AWG wire to achieve less than 10% voltage drop for that length. I guess that's not too bad.
I've just switched ALL my lights on. Running lights, steaming light, tricolour, deck lights, the works and my amp meter went from 2 to 10. And mine are all either incandescent or halogen, no LED's.
You should be able to get a nice tan under your spreader lights
20 amps x 13 volts = 260 watts. Whew.
