Given that Hunter supplied some nice drawings of the standing rigging I started using them as a baseline reference in my analysis. The drawing below nicely lays out length dimensions but neglects to mention diameter of pins (I had to go buy a new calliper as I couldn’t find my other one :) and now have to go to the storage area to measure)

It also references the term “C nut”.

I wasn’t exactly sure what a “C nut” was so back to the internet!

Who would have thought the connector is shaped like a C ;) however is sure doesn’t look like a “nut” to me.

Pretty clever when you think about it. The pin let’s the turnbuckle rotate in the forward/aft plane and the C-nut lets it go port/starboard. In other words a flexible joint made with rigid components! The human mind never ceases to amaze.

Counts as my “learn at least one new thing a day” ! :)

I found this during my “research”. Somewhat over my head but I found it amazing the level of detailed engineering that goes into the design. I’m beginning to understand why the modern foiling boats cost so much.

Well I've read quite a number of articles about swaging and mechanical fittings and got stuck watching the videos of swaging machines in action ;) so I think I know enough about the process to have an informed opinion about what I eventually decide on.

The following is what I found to be quite a good summary/comparison of the two approaches.

Interesting (at least to me :)) article published by the International Institute of Marine Surveyors on synthetic rigging. They also publish a guide that sells for £20 for the e-version

"Self Help Handy Guide – “What a Marine Surveyor needs to know about Synthetic Rigging”, which covers the subject in greater depth, provides data and suggests types of inspection required for synthetic rigging." for


I have attached a PDF version of the article. Sorry about the fuzzy text but my PDF file generator didn't work properly on the webpage so I had to screen snap it all.
