You''re certainly right Sailorman and 73mensailed, the skipper and boat owner are by far the primarly responsible (devil''s advocacy aside), but unfortunately its the manufacturer who will pay....deepest pockets.
Although one thing disturbs me about the Mac 26. Given a calm windless night, why didn''t the Mac right itself immediately after the adults on deck went in? Instead she stayed over and immediately filled with water, drowning the children. You would think that when the weight of the adults well above the CG was removed, it would pop right up, even without the tanks full. Maybe someone with some design skills can enlighten me.
