A few months ago I had a problem with the furler on my Oday 28. Specifically, the jib halyard experienced "halyard wrap", where the halyard wrapped around the forestay. By the time I got the sail down, the hayard was severely frayed. I cut the line above the fray and tied on the shackle with a bowline. After fixing the furler problem, I hoisted the jib and sailed the remainder of the season.My question: Can I sail next year with the shackle tied on with a bowline, or must I replace the halyard with a spliced-on shackle? The knot held for this season with no problems.
