At 0:35 seconds in this video you show failed piece; there is no corrosion on the piece. It failed where the radius begins; completely fracturing on one side and there are cracks on the other side as well (very small cracks). The fracture at the top where the pin was; failed because it bent quickly and simply 'tore' it off. No corrosion there. In aviation high stressed metals need to be radiused properly on ALL edges to remove 'stress risers' that will turn into cracks; precipitating the failure. The failed rig; to me; simply looks to thin; no corrosion (pitting)

Don't get me started on GLASSED-IN chain plates. Whoever thought that was a good design idea needs to be fed to the hogs.

Crevice & stress corrosion ... anyone doing blue water likely needs to change their rigging every 10 years, as mentioned.

Edit. Just cause it looks "beefy" doesn't mean it's not near the end of its life. The Bav 44 Ocean you pointed out had significant surface rust, which may be of concern.

The fact is, like blades within an airplane's jet engine, all these parts are life limited and should be changed out periodically. Given they are a critical "safety of sail" component, people are nuts to wait until near failure.

Since we aren't using ultrasonic methods to inspect the metal, nor know the number of cyclical loads, a change-out periodically (e.g. 10 yrs) is our only saving grace.

I have been a jet aircraft mechanic for many years, I would suggest you search for a galvanic corrosion charts for dissimilar metals and if all of the metals used for the entire assembly are EXACTLY the same levels of all the metallic parts down to molecular level there will be low corrosion. If any of the parts are slightly different there will be galvanic corrosion. I have used Teflon isolators as bushings to stop the corrosion. You can get very tough Teflon stock to make them from it would also be a visual indicator for wear and an easy replacement even under way.

A keel stepped mast gives more peace of mind. Deck masts, one fail in any part of the rigging and it’s all over.

Wow, what a thought-provoking video! It's amazing how this one simple practice could have made such a difference. I appreciate the insight and analysis you provided, James. Your collaboration with Chris from C C Rigging really paid off, as his expertise and willingness to educate others truly shines through. It's great to see the sailing community coming together to share knowledge and experiences. Keep up the fantastic work, and thank you for your time and effort in bringing us these valuable lessons!

I see some are switching to titanium fittings on their boats refit, so is titanium better or worse for long term corrosion and fatigue life?, anyone know?
