Given the weight of the keel the stub wrenched side to side until it failed. Keel bolts must be embedded in the lead, then led through a solid structure before fully penetrating the grid or stringers. Oyster should be ashamed."
An interesting read on the polina star, post above quoted from another forum. Not so sure CNC did things so right all the time, but will note that the Mid 80's 33, 35, and IIRC 41 were all designed as the poster suggests above. Their execution and approach to this contributes to the 'sinking mast step' phenomenon that happens to some of these boats. (Slowly, detectably, and after being flogged for 30 years...)
