I have a 1996 H280 with Z-Spar mast and would like to install a spinnaker halyard. There isn't an old one there now to use as a pull line. I had just about decided that I'd somehow (don't know just how yet) make my way up the mast to the existing spinnaker sheave (fixed and about 2' above the forestay), drop a fishing line with small lead weights on the end over the sheave and down inside the mast and have someone grap it through the mast exit. I checked yeaterday and that exit slot is about 7' above the deck. Am I headed in the right direction with this or do I need to consider a different way to install a new spinnaker halyard?
