I have a 15' aluminum v-hull mastercraft- big fisherman. When someone is in the front seat it rides and drives great. When i am in it alone and sitting in the rear it is like a sailboat !! I need some suggestions on how to control this problem. Do i put some weight in front ? I am going to move my battery up front but i dont think that will be enough. I also did buy a set of doul-fins hoping that will help it plane out once i get going. Thanks for any ideas, Erik
