In my opinion, hull design has more to do with how fast a boat will run than almost any other variable. Coatings, sanding, blueprinting usually only give you results when you are starting with a hull designed to run fast from the start. You are most likely wasting time and money if you are doing any of this to a mainstream bassboat.
