The method I use and I believe it is very simple is as follows:
* (2) Green sticklights from BPS. Drop one over each side of the boat.
* (2) Poles per person, one in the rod holder, one in the hand (drop the one back in the holder that doesn't have the fish on it.
* some type of light onboard that you can turn off when your not baiting your hook, I have a simple light with clamps that hooks to the same battery as the green lights.
Just that simple and it works. I try no to leave on a light in the boat the whole time or it attracks bugs. The ones over the sides are in the water so they don't bring the bugs into the boat as much. Some people submerse there green lights, but I just leave mine on the surface. It's fun for the younger ones to watch all the fish that they attract that way.
