I lived in the Carolina low country for a while and heard of gig fishing. Fishers go out at night in flat bottom boats and cruise the salt water marshes looking for flounder lying along the river banks. Using a lantern, you can see the fish on nights with clear water. Flounder initially rely on their camouflage, presenting an opportunity to spear with a gig spear, effectively a trident-tipped pole.
I am always looking for new ways to push my kayaking. Gigging was great fun and an awesome excuse to go out at night. After chartering a few trips, I was ready to try giggin' from my kayak and needed a gig spear of my own. Rather than the typical 12-foot pole, I made the following 4-foot pole that can attach to my 2 piece paddle, by switching out one paddle blade.
Out on a trip, I slowly stalked the shore looking for fish. The shoreward side was usually too shallow to paddle. Poling would stir up the sediment and obscure the hunt. So I'd paddle only on one side and the gig trident was ready to spear flounders. When not hunting, the gig could be detached and stowed the kayak deck, out of the way.
