Performance issues - Hull thickness - inside t'ducer mount

I am mounting a transducer in my Wilderness Pungo 120. Sit inside. Has a noticeable V at the center line where the transducer would go. At that location the hull is much thicker than that of a flat bottom yak. Hard to be exact, but probably 1/2 to 3/4 inch.
Will this thickness effect the performance of the FF, or put another way, does hull thickness effect FF performance.
Thanks for your help.
