Amsteel Blue Breaking - Not during saddle use

[bowkill00]

Is the climbing rope dynamic? If so I'd maybe give it a small preference as a backup if there's much slack (and I'd minimize slack). Otherwise I'd choose by which gave me the best feel moving around in the saddle.

I think it's static

Not sure how to gauge the wear on the Amsteel, it certainly looks more worn than the Predator used on my linesman and teather which still looks new? I’ll put on a new bridge for next season.

Not sure that anyone actually knows how to gauge the wear other than looking at it. The general consensus seems to be to change it out every year or two. If you don't mind me asking how old is your bridge in that picture and what does it look like inside the loops where it rubs on the saddle fabric? I'm sure that bridge is still plenty safe but I'd change it for sure if it were mine since no one seems to know how much the wear weakens it.

Good questions! I put the bridge on the Kestrel new this spring. I’m embarrassed to tell you I never really examined the inside surface of the end loops (until now...). After looking at the inside of the loops I’m definitely going up to Wespur and pick up a new length of Amsteel! I practiced with the Kestrel and Klemz platform (thanks to @BCHunter!) all summer, at least 3x per week. We had rain or snow most hunts this season: we camp in the National Forest so our gear never really gets to dry out, perhaps the heavy use & lack of care took its toll on the bridge?
There certainly are a lot of filaments in each strand of the weave....

Thanks @Charliea . That's about what I expected to see for wear based on what I'm seeing after 8 hunts. Furthermore, it gives me a baseline and visual proof that if I continue to use an Amsteel bridge, it will be replaced every season.

What diameter is that BTW? It looks way larger than the stock Mantis bridge.

Any chance that is just an Amsteel rope and not Amsteel Blue? Mine does not show anywhere near those signs of wear from a full season of use now, so just wondering.

This chat has convinced me to have a backup bridge, and I plan to incorporate a 7/64 amsteel bridge that is an inch longer than my primary for this purpose to keep it light and simple. Both will go on the biner when I hook to the tether.

ive come up with something that may be the cause of my amsteel blue breaking. i pulled this off the samson site. i have never paid attention to twist. every twist per meter significantly reduces the strength of amsteel or any rope for that matter. i went out side and looked at my winch rope and its almost impossible to tell how much twist is in it but there is some. i have never had swivel before the hook as you would have on a crane. i just pull myself out and winch it back in without paying any attention to twist as the rope is so limp and flexible. i think this and the repetitive side loading at 90 degrees and water and dirt all attributed to this failure. i still think this is a great product and will use it forever as a winch rope on my 4 wheeler. i may incorporate a 4ft piece of flat webbing when plowing. still on the fence for using it as a bridge. like many guys said. its easy to change it out annually if you feel its wearing a bit.
thanks for all the constructive discussion

Same here, mine looks great. Even the cam over rope for my platform looks great. I only buy amsteel blue, not the cheaper amsteel or the cheaper yet winch cable from china.

I'd like to backup my amsteel bridge with a slightly longer webbing bridge. Not quite sure how to tie it in though. Any videos or pointers?

Personally, I think we have gone bat **** crazy on the weight savings and bulk reduction of certain things and bridges are no place to be messing around or experimenting.

Amen....

Diameter is 3/8” or 10mm, the thinner grey Amsteel on my back strap bungee is 5/16”. I’ve used one of the grey short back strap lines with sewn loops to lift the 225 Yamaha off the transom of our boat. I have total confidence in this high strength hollow braid line, just need to maintain/replace it regularly as others have wisely pointed out.
I got the 3/8” Amsteel from a bulk spool @ West Marine for $2.30-2.50 per ft, something like that. West’s point of sale literature claimed a tensile strength just shy of 20,000 lbs for the 3/8”.
I got the grey 5/16” with pre-made loops from Davis Instruments. The tag ends in the hollow braid are sewn through the entire length from eye to eye.
Appreciate your feedback @Jasper2, it’s all pretty new to me so I’m learning as I go!

I would think tethrd did, but not sure.

I work on a 3000 ton 280’ Offshore Supply Vessel. We use 2 1/2” and 3” blue Samson 8 strand tie up lines. They are abraided scratched up worn out and still hold this monster in fifty knot winds. It will wake you up hearing it stretch pop snap but rarely breaks. It does happen but not a lot. Almost all ships are using this over nylon now days.

Just my 2 cents.
