I don't think that the Permatrim will increase your top speed or fuel economy--it might get the boat out of the "hole" (up on a plane) slightly faster, and it would put the bow down for a better ride in chop. So, I would say it is a worthwhile addition for that alone. In the NW Florida waters there are plenty of times when the CD type of hull pounds--and that is why we have the Tom Cat here.
