The current halyard on Temptation II, C-27 (5110) is a rope to steel cable hybrid.(not spliced, but mechanically joined with shackles.) Needless to say, this arrangement gets hung up as the connection passes the side shrouds. I want to replce this with an all rope halyard. Is the sheave at the top of the mast designed to accept either the cable or a rope halyard? What diameter is recommended?Thanks
