So that when you shoot your first arrow into the shark or ray you can have someone shooting backup and put an arrow in the shark or ray with the laundry detergentjug attached while you grab the rod with the line attached and hold on for the ride of your life. Also make sure you have along handle gaf handy so you can hook the animal and pull it into the boat. This is primarily important when shooting stingrays or cownose rays.
