Hey Scotty. New to you boat. Fun times for you.
Rigging.. It is the key to sailing happiness. Even a great rigger can only best guess how munch more time you will have in your existing rigging. If you have concern the time to change it is now. They have no idea how you will sail the boat. What stresses you will put on it in the conditions you sail/cruise. If you are that mystical grand mother sho only takes the boat out on pleasant Sunday afternoons in gentle breezes, then your rigging could last many years. On the other hand being the rough and adventurous sailor braving the Golden Gate winter storms every chance you get might have the rigging down about your knees like my grandson rushing to get to the potty.
Rigging is not just the wires.
- It is the mast.
- The spreaders.
- The way the wires are attached to mast and hull.
- The condition and size of the wires that form the shrouds.
- If rod rigging it includes the rod heads and the slot connections in the mast.
- The pins connecting the shrouds to the chainplates.
- The chainplates.
- The hull or bulk connections of the chainplates.
- The symmetry of the system.
Only way I know you can get assurance for ocean passaging, is to take the rig down and have each component examined and replaced should it need the service. While you have it down clean up any poor design or provide improvements to the systems so that they all work together. This means boat Mast and Boom rigging.
When I did refit the standing rigging to my 40 plus year old boat, the cost was about $11K all considered and took 2.5 months with mast in the boat yard. This included new furler, shrouds, refurbished chain plates, mast electrical, mast head with spinnaker crane, sheaves, pins, all running rigging, and mast winches.
Knowing that the rig is properly prepared, I have confidence in sailing the boat in all conditions I might encounter.
