The 4 boats that were lost in the recent storm off NC were all ruggedly constructed blue water boats that were simply overwelmed by conditions OR had gear failure more related to maintenance than construction. (i.e. engine failure...steering cable failure..drogue rode chafe). On the other hand, we have had some gear failures due to construction like the Hunter off Hawaii...and other failures due to poor seamanship (Barnes ...IMHO).
So... I don't think the overwhelming trend to lightly built production boats has much to do with abandonment stats overall since the vast majority of those boats are sailed in the waters they are designed for.
