I kinda doubt the mold symmetry would be that far off. You are using a measurement from the bow which could be affected by the bow point or by the bow in the unsupported hull. From this measurement your picking a point and measuring the height between to hull transitions introducing another possible measurement error. If you pulled a string long down the center, are the measured points the same distance from CL? Perpendicular to CL. There most certainly can be a difference, but in the end, they custom fitted the halves together, finished, and sold the boat. My intimidator top/bottom were 3/4" off, so they ground a bevel on the top half, flexing caused it to break along all the penetrations. I suppose in the end, what could you do to correct this error?
