The halyard on the H16 runs over the top pulley to the front of the mast. There is a ferrule swaged onto the wire halyard which will hook onto a "Tang" on the front of the mast when fully hoisted. You then tie off the halyard tail so it doesn't fall in the water. The older styles like mine have two ferrules, 1 for reefing the main. I think the newer boats don't have the second ferrule.
Good luck,
