Looks like a lot of surface corrosion on everything- I would replace. Also, pull the chain plates and do a inspection using magnifying glass.

Is the rigging quote for the Potter 14? that picture does not look like potter rigging. even so the corrosion in the pic is just on the surface and can be removed and passivated. the wire with a swage end is the component that should be changed at least every ten years. if you have reusable wire end fittings then only the wire

I know the forestay and backstay were changed, as I was given the old ones.
Thoughts?

It's not clear if all standing rigging was replaced.

The wire is 1/4", she's a 30' sloop.
Dies must match the size of the terminal and terminals much match the wire. It's not uncommon to find different diameter wires on the same mast.

I have used the "Spotless Stainless" passivating solution on much of my stainless. This includes shroud swage fitting, chain plates, bow and stern railings, my Monitor Windvane (316 SS) and other fittings. I have also used the Wichard passivating paste.

Wichard - Wichinox Passivating Cleaner for Stainless Steel

I like the Whichard the best as you can also polish the stainless at the same time. What I find is that after a few months the corrosion is back- even on part that I know were well made like the Monitor. It seems to me, after a certain age, stainless starts corroding to the point it cannot be return to near original condition. Maybe microscopic pitting is occurring and passivation just does not last. I can get all my stainless to look new by polishing and waxing, but in a few weeks, corrosion begins. I do get a lot of salt build up due to near by breaking waves and sea spray. The other problem is that stainless can start corroding from the inside- once the passivating layer has been breached- one may get the part to look nice and shiny, but it has lost strength.

If you bothered to read the thread, you'd realize that the issue is brand new rigging corroding. Forgive me for being concerned.
Do you know what effect a little surface rust has on the strength of stainless steel? None at all.

Re: Why buy new rigging?

I would think that waxing stainless steel is a bad idea. The wax would create an oxygen barrier and promote crevice corrosion.

I have a sauna on my boat, therefore I win.

I thought that too, then a friend gave me this:
Collinite Insulator Wax:
•Car, truck, boat, bike, RV, aircraft, personal watercraft, snowmobile, ATV, tractor/farm equipment, golf cart, snowplow.
•Exterior gel coat, fiberglass, clear coat, single stage and lacquer paints and highly finished wood.
•CLEAN, unblemished painted/unpainted metals; chrome, stainless steel, aluminum, copper, and brass
•NOT recommended for rubber, non-skid, black trim, vinyl, glass or non-painted plastic.


Insulator Wax Collinite

I have used it and it does prolong the passiivating and polish of my stainless. I guess once stainless is passivated, creating a barrier to salt spray (which dries and leaves salt deposits) is a good thing. If one sails only in fresh water, or does not have a salt deposit problem, wax probably not needed.

That's right.. To get crevice corrosion happening in the first place, the 'corrodant' (eg. salt water) has to be able to remain in continous contact with unprotected metal. If all cracks and crevices are sealed with wax, regardless of whether or not oxygen can get in, the salt can't get to it either and crevice corrosion doesn't happen. This is one reason products like Lanocote were developed.

EDIT: You might not have a salt deposit problem in fresh water, but depending on where you are you might have an acid rain/smog problem instead and a wax barrier would still be of help.

Obviously you have no idea how overbuilt the Potter is


That is from my Ericson 32.
