My C&C 30 Mk I, possibly hull 19, had its halyards exit at the base of the mast through a turning block. The halyard then led horizontally to a winch on the box structure molded into the cabin top. All halyard loads were not transferred vertically to the deck. My 1981 C&C 34 has numerous halyards exiting the base of the mast and led to blocks on the collar which was bolted to the deck. Blocks then turned the halyard to wherever the winch was located. Before the tangs were used, I heard of at least 1 local C&C 35 of unknown Mark having reports of the deck lifting. The halyard loads were transferred vertically to the collar which in turn caused the deck to deform flexing upwards. The tang were devised to anchor the collar to the mast to eliminate the upward flexing of the deck.
