Looking for any info - setback boxes
 

I know, I know... this subject is beaten to death from time to time. I just finished reading through several searches. It is fairly evident that resulting change in performance when adding say 12" boxes can vary wildly depending on the hull length, design, weight, center of gravity location, etc...

So here's my question. By chance, does anyone know of a 292 Fastech Formula or similar twin stepped, twin small block, 24 degree V-hull that has added setback boxes? Did it like the change? Thanks.:drink:
