Sometimes that long lining/dragging can catch a lot of fish,but I have found that a bottom bouncer worked/caught better.The bottom bouncer works better due to the line out is shorter and there more action on the lure.The rocking of the boat from the waves can be deadly as the lure gets pulled upward and flutters back and down.Used to use two rods all the time out in the flats (30fow) with one bottom bouncer and me casting the other.If holding onto rod,long lining,can catch better if you lift rod high and back and then put rod back down with slack.Let boat pull up the slack and feel for the weight of a fish.Then set the hook hard.Lots of stretch long lining with mono.
