Quite often, your angler will be fighting the fish out to the side of the boat and merely winding the slack line in. And while the line might be slack at the angler’s end, it is not at the fish’s end due to added pressure from all the line and the lure dragging through the water.
This technique has a dramatic result on the behavior of a fish too. Most of the time, the marlin will stay up on the surface much longer and not go deep right off the bat, following its initial run. This in itself can allow the crew to get a quick shot at the leader. The fish can be green at this stage, and it is not always possible to get the release or hold on to a wild fish. Sometimes the leader man will need to dump the leader, and the fish will then sound and want to go down. When this happens, the angler can really apply a large change of drag pressure on the fish, and I will have them go straight to sunset drag. On most occasions, this large and sudden change of drag pressure will cause the fish to head back to the surface. I will once again have the angler back off the drag, and we will repeat the process until the marlin is captured.
