Nothing is more heartbreaking than reeling in a fish and losing it when it is almost within reach.
So make sure to construct a gaff hook before you start your fishing. Find a strong thick stick about as long as your arm. Using some rope, twine, or even fishing line, lash the hook tightly to one end. Use the nails to nail the hook securely near the end of the stick, then take some twine, rope or even fishing line and firmly lash the body of the hook to the stick. Typically, one loses a fish when it is being lifted out of the water.
