Genoa
George, it is difficult to understand exactly what you are referring to on your genoa. If the tear is along the line where the sacrificial cover meets the sail, then is makes sense. IMHO, you have three options: buy a new sail, take or send it to a sailmaker, search for Sailrite.com and repair it your self. Naturally, you must remove it somehow either way. Sailrite offers the materials to purchase to make the repair. An adhesive backed 6oz Dacron tape is my favorite. WM has the stuff in 3 in. by 15ft rolls. Apply it over the tear on both sides of the sail. Then, using a zig zag stitch, sew it in place along the edges of the patch.It must be a zig zag stitch. A zig zag flexes with the stress put on a genoa. Some DIY's make the mistake of using a straight stitch when replacing a sacrificial cover, or making a repair. This might hold for a while, but eventually it will tear just like perforated paper--it tears along the line of the perforations. The tighter the stitch the sooner it rips.It would be best to see the problem before making recommendations on repairs. I believe Sailrite offers tips on doing this type of work. Look them up and see if you can find help there, or as I mentioned follow options one or two. If the sail has started ripping due to the stress of sailing, it might be best to replace the sail. Best of luck to you.
