A forward moving boat will aid in maintaining contact with hook points and a fish's mouth. As skirts are run direct from a rod tip or from outriggers , one is allowing instant strikes to set hooks from solid 'No Slack Systems".
Every strike is different, some stick, sometimes they don't. Fish jump for a reason and that is to try and remove the foreign object from their mouths. Fish are capable of faster head shakes and revolutions once clear from the impeding water that offers more restriction to their movements. Many fish run and jump early in a fight , going balsitic in a spooked state or in attempt to dislodge the item of food, or lure from their grasp. Maintaining, or increasing boat speed will help keep your line tight (mono),or it will stretch it to a point that makes it even more difficult for a fish to shake the hooks free. Pelagic fish often change direction quickly and unexpectedly, and a moving boat will help reduce slack line by moving in a forward direction, thus lessening the chance of hooks falling free whilst 'slack' has been created.
