Standing Rigging
You can get individual pieces of standing rigging, or whole sets, made up for you by just about any rigging shop or places like Defender or Sailnet. Best to remove and bring in, or send in, the old rigging, so the new stuff will be sure to fit. The key things to think about is making sure the measurements are correct, that quality materials are going to be used, and most of all, the swages are done correctly and professionally.An alternative is just to buy the right size wire (from the above places) and use re-usable end fittings, like Norse, but they are expensive and only worth it if you think you'll use them again in the future.
