[C320-list] New standing rigging

[jackbrennan]

I paid $2,200 in Florida to rerig my 1998 320 about 18 months ago.About seven broken strands in the back stay. Chain plates et al were fine.I agree 10 years is about the max in saltwater, especially if you do a lot of sailing in varied conditions.If you sail one Sunday afternoon a month on a lake in 10 knot winds, this rule may not apply.Jack BrennanSonas, 1998 Catalina 320Tierra Verde, Fl.Sent from my Samsung Galaxy smartphone.

In tiny gaps where water collects and becomes stagnant (loses dissolved oxygen) you can get crevice corrosion (see my article on our website about crevice corrosion around a weld to the stem head causing loss of the forestay)In the UK most insurance companies require standing rigging to be replaced every ten years. Mine doesn’t, as it happens, but they do say that I am expected to keep the boat well maintained and so if a 10+ year rig came down and corrosion was found I guess they’d try to avoid paying outI bought my boat when it was 20 years old and PO had never replaced the rig. I stripped the old rigging with the mast down and refitted new, employing riggers only for the re-tensioning  once the mast was up. Total cost was under the equiv if US$ 2000As you say, getting the stainless locking pins out of the alloy spreader roots was a nightmare. When replacing I used a lot of “duralac” to protect  them against future corrosionHope this helpsGraeme#366 1996Sent from my phone.

They don’t look like a catastrophic failure is imminent. The only ones to cause a crisis would be fore and aft stays. What furler was the original a Shaeffer?

I have hull 78 so she’s about 25 years old. I’ve been putting off the replacement of the standing rigging for a long time, I’ve heard you never want to go beyond 20 years. I bit the bullet and did it. Had a rigger do it in the slip over a month period of time. While I was doing it I replaced the jib furling with a Hood Sea Furl 707. Also, removed all the chainplates and resealed them. All new hardware, turnbuckles, etc. The only hangup on the project was the spreaders have to be removed, which was a challenge as they didn’t easily come off, there’s some pins that hold it in and they were fused together to the spreader, different alloys or something like that. Total cost on the project was about $6000. Why I’m sharing this is I took some pictures of the rigging, cut it off to see how the cables looked inside. Although it was pretty rusty on the inside, sure still looked good. For those of you that know more about this than I do, perhaps the integrity of the cables have diminished, but I found myself wondering if it really needed to be replaced. Either way it’s a $6000 sunk cost, but wondering if any of our smarter members want to chime in on this topic. My boat has been in the southern California oceans from day one, so always around salt water and I figured it was due. >> >> Here’s a link to the pics of the cables when I cut it off and opened up the strands https://drive.google.com/drive/folders/1pyxsZK57NTpUVN-GH7Np4dz8us5MoRPO?usp=sharing <https://drive.google.com/drive/folders/1pyxsZK57NTpUVN-GH7Np4dz8us5MoRPO?usp=sharing>>> >> Not really looking for anything, just wanted to share this with everyone.>> >> >> Jeff Brown>> "Out of the blue" Dana Point, CA>> Catalina 320, Hull 78>> (949) 350-5123>> oceanblues at mac.com>> >> >> >> >> >
