SO I may be missing something but if the boat is going a certain speed over ground (based on your GPS) how is it that your lure can go slower "or faster" then the boat for any prolonged amount of time? I can see currents maybe influencing the lure action for short bursts but eventually that lure must follow the boat at the speed the boat is going. If my boat averages 2.5mph for 1 hour I suspect my lure will have averaged the same speed over that hour as well. I am a novice here so tell me how this works.
