Gaff hooks are for the larger fish. You physically hook the body to help land them. The larger fish still have a lot of struggle in them and it is heartbreaking to lose one at the last minute. You will want to inscribe a small groove at the end of your stick to secure the shaft, nail the eye and wrap with a bit of string. In a maritime environment, secure some bait to the large hook and throw skyward to attract seabirds. Pull in with your line and prepare for a fight.
