1968:

M/V Triple Crown foundered off the coast of Southern California with a loss of nine lives while retrieving the anchor and chain of a large offshore drilling rig.  At the time of the casualty Triple Crown had eight anchors and 26,000 feet of chain on board, the weight of which caused a low freeboard aft.  Three-to five waves washed over the stern and entered a stackhouse door that could not be closed due to the location of one anchor on deck.  The engine flooded, the vessel listed to starboard and sank.  The Coast Guard investigated.
