Two years ago I built a Sailrite spinnaker kit. I used a home sewing machine without difficulty. Recently the spinnaker caught on a mast fitting during a race. The head and one leach were completely torn off. I called Sailrite, (800) 348-2769. They instructed me in how to reattach the head and sent me replacement panels for the leach. One week and $100 later the spinnaker was flying again. Great service!
