On our H25.5, the old halyards are just too worn and stretchy. Might be the originals. I've ordered new halyards and expect delivery in the next week or so.The old halyards are 3/8" or 7/16" (probably Samson XLS) and and are still in place and operational. The new ones are 5/16" Sta-Set-X. How do I replace the current halyards? How do I get the new halyards run through the system?
