Thats a pretty good answer. 7x19 in general is not as corrosion
resistant, as the thin wires cannot be properly galvanised with a thick coating of zinc. A lot of the stuff I've seen almost looks more like it is electroplated and it doesn't last long in the marine environment
unless very well looked after with rust preventatives. We had a good run on my folks boat
with 6x19 rope core
stuff. Well soaked in fishoil and linseed and smeared with white lead paste... lasted about 30 years. The theory being the rope core
soaked up the oil
and released it under load.
It could have been 7x7. Much better for standing rigging than 7x19. Nearly the same stretch for its weight as 1x19, easy to bend and has good galvanising, at least when you get up to 10mm size. The smaller sizes don't seem as durable.
1x19 or even better 1x7 would be perfect, but its hard to find it with the highest tensile grades. Normally 1x19 is 1500mpa and the 7x7 can be 2000+mpa 1x7 is often only 1200mpa but has very good galvanising. 7x7 has the big downfall of being pretty rough on sails
Sounds like your rigging did its job, at least for a while. I do like how galvanised rigging shows its condition honestly. No surprises, especially if it isn't painted black.
