    when (over?) loading any modern sailboat course stability inevitably has to suffer: the hulls having very much more volume in the back than front, with the (over?) loading the CG will move backwards & thereby aggravate any yawing. Putting more load in the front will not help either, as this will move CLR forward (the comparatively fine bow is immersed further), again aggravating yawing.
    Before doing any serious grafting under water, that will require extensive remedial surgery if unseccessful I would try something exterior:
    transom mounted casettes with dagger foils, either fixed("stern-daggerboards") or as twin additional rudders. Can be deployed or retracted while sailing & easily taken off from their pintles
