Any Marine shop can make new stays, bridal and trap wires, if you take your old ones in they just copy the length or you can phone your local Nacra dealer. If the only damage to the tramp is a small hole, you can take it off, take it with you to the local marine shop and they can patch the hole and restitch any seams that need restitching for not much cost.
Enjoy your sailing
