A few factors I have found, Improper center of gravity, Wrong lift charecter prop, Center step placement needs adjustment( I have done this) Spray rails also need adjustment. And the deck of the canopy models hop worse because the air doesnt stall on deck properly and no low psi is not created midship back. This affects the angle of attack on the bottom. Many cats can hop but if you know where to look and fix you can get it out. Lots of folks like to cruise at 60-75 and the hop is in that zone.

Exactly!!

Dam................. That was like it came out of a text book. I have been reading alot about "porpusing" and hull supression... VERY interesting. You can get the"hop" out of a boat.. Like Tres said.. It takes Skill and $$$

I have never rode in one but heard it is a nice running boat with no bad habits.

Goes back to the drafting table where cleverness along with the math skills of the designer comes into play.

Wrong CG & bravo drives!! Install 5s on boxes or 6s and some real props and the problem goes away..
