Hmmm. I just bought a 7/16 pre-made main halyard for my 1981 E38 from Defender, brand "Novabraid", which included a headboard shackle spliced to the line. I was a little dismayed to see the splice appeared to increase the diameter of the line to over a half inch. I had climbed my mast to measure the sheave a couple weeks ago, and the width was 9/16, and now I'm afraid the line will bind as the splice passes over the sheave near the top of the hoist. I hope I'm wrong. My current halyard is a line/cable spliced assembly which was on the boat when I bought it 13 years ago, and which I've been dying to get rid of. If the new one doesn't work, I'm going to be well & truly stuck.
