I gig from my 16' jon boat. I'm in FL, but it's going to be the same. I use Starfire II shrimp lights and run them off of a battery. Use a separate battery for the trolling motor. As said previously, they aren't skittish at all at night. Quite often I've literally trolled right over their head, stopped the trolling motor and used the gig to push myself backwards, and sure enough, they are still sitting right there, never even flinched.
My friend has taken up bowfishing, which he does for flounder, sheepshead, and black drum. He mounted a 100w halogen aviation light to his bow and pretty much what the light is looking at is what he's aiming at. Pretty cool, something different to think about. I stick to gigging, I can't shoot worth a [censored].
