Nylon Thimbles in Anchor lines

Started this job without doing my homework....
Does anyone know how strong those white nylon thimbles are, I've eye spliced one onto the end of my 14mm anchor line, it looks jolly neat! (wormed it as well) and am now concerned that if the D shackle inside it is pulled hard in cold water the thimble might snap or will it simply deform/stretch?

You can break them where you will not break an SS one but the SS ones will damage things if left to swing about , 6 of one doz of another Des

Will leave as is until it breaks, might not! Was planning to do the same for the painter line again in 14mm so we could be towed by it if required, might not now, unless members have done this and its worked fine.

There are lots of books and drawings that tell how to do something but I've struggled to find one that tells of the relative strengths and weaknesses or unwise combinations. Know its a big subject so the variations will be many and complex.

I had nylons on my..........

........Hunter Horizon 23 which, I moored on a chain throughout the season of 2002/2003. The mooring strops had nylon eyes spliced into them. I never had any problems and it was a specific area I paid attention to when doing my weekly checks. I'd add that whilst on the mooring she used to take some real hammer.

.........for this kind of information if it concerns/interests you that much. Do a search for a Mountaineering Forum or a manufacturer of associated equipment such as carabiners. I would imagine you'll find info on stress related cracking. There is, I believe a specific reason why carabiners are made the shape they are - I recall seeing a programme about it on SKY some time back.

One thing you can guarantee is that a rope will always break on the splice Draw your own conclusions Des

We used to break loads and found that SS was the only way to go admittedly we were using then on a racing yacht. They fail by stretching and falling out of the loop or by ozone damage and shattering The SS ones would rip the end off if they were going to fail. Des
