During a recent nor'easter the jib halyard was ripped in two. How do you get a new sheet through the mast. I have an O'Day 192.
I take it that you have a mast with internal halyards Mfg by Z-Spar, right? Where you have a main halyard in your mast also, and you don't want to get your new halyard crossed with it, if it was me I would remove all the stays and spreaders from the mast to make handling of the mast easier. It's always a good idea to check your stays every year anyway, particularly the swaged fittings and turnbuckles. Then set your mast on something at working level and remove the mast head plate with the light so that you can see down into the mast with a flashlight. You probably can't remove that cast Aluminum tabernacle because it's riveted to your mast, so you're going to have to do the best that you can by using an electrician's snake from that end where the sheave is, to run it into your mast out through the top of the mast. Once you are able to do this, tie a strong twine to the end of the snake and pull it back out over that sheave on the Tabernacle and tie it off to the mast cleat. Then go to the other end of the mast with your flashlight and put some tension on the twine and see if you can see that it isn't dipped with the main halyard. You should have the main halyard tight and cleated off. If the string is separated from the Main halyard, take a piece of a coat hanger and put a small hook on the end and try to hook the string at the Jib sheave block. If you're able to hook it, throw a little slack into the twine and pull it the twine out over the Jib block sheave. Cut the string at the mast head if everything still looks good, and pull the rest of string out through the Jib block the rest of the way. If your main halyard is not too good, this is an excellent time to replace it. Just hook another twine to the end of the main halyard at the exit plate on the mast and pull your halyard out from the top of the mast whereby pulling the twine into the mast. Purchase some new halyards and use the strings to run them back into the mast. Good luck with that.
