ok ok, so the rest of the story.....i had purchased new 90' halyard, spliced it cleanly on the sail end after cutting shackle off and about that time had 2 friends show up on my boat. got distracted and pulled the wrong end til my friend said " i think you're pulling the wrong way. turned to look and line had already disappeared into mast. removed bottom sheave to see if could fish it out of bottom of mast- not visible, tried whipping the old halyard from aft side of mast to encourage it over the top of sheave and mast so it would fall back thru to bottom. of course the whipping action caused the rest of the halyard to fall to cockpit floor. which led me to original post. boulevard pale ales might have been contributory to my stupidity, but it mostly is innate. i do feel better, thanx for your patience and careful replies without commentary. will fix my blunder this weekend. guess it makes sense to just hoist the main with the old existing 2nd halyard and see if it pulls cleanly to top of mast. if it does, i will splice onto it and pull bright shiny new one up.
