It would be interesting to have the straight line mast head to chainplate measurements to know if the truck is truely centered amidships. You can get this by bobbing a halyard assuming a calm day and assuming that your sensitivity to the pressure you put on the halyard is good or that you hang the lead from your lead line on the halyard end to give a consistent halyard stretch.
But a little asymetry in the boat's construction is also not impossible.
