I have a 1993 Hunter 37.5 with an Isomat NG70 Mast. It has four halyard exit block at the base of the mast. There is one unused on each side with a messenger line in it. I assume one of these is for a spinnaker. I want to add a spinnaker halyard for any asymmetric. Is the entrance sheeve above the forestay attachment point and if so about how far. I am concerned that there is enough room for the snuffing sock. Which side does the spinnaker halyard exit, port or starboard. Does anyone fly an asymmetric from the built in spinnaker halyard.
