Pin Kit Rope

Hey Buzzards,
Just finished my swift water rescue class and I am putting my kit together. I am look at getting Polypro line and was wondering if I need to go with the Diamond weave or three line pattern. The 3 line pattern has similar break ratings but is a lot cheaper. Thoughts?

I'm not sure what you are referring to --- but hopefully not the stuff from Home Depot.

If you want to unpin a raft you should look into 1/2" static line rated for rescue operation. People have opinions, etc on what is best, bluewater II is an example of something sufficient.

I second this. You need to go to a climbing/rescue 10 or 11 mm static line, like what you would haul a haulbag with (i.e., not dynamic that you would be leading on). Mine is 200 feet long. The forces generated during mechanical advantage recoveries are huge. Did they not cover this in the class??

yeah Nathan, polypro probably not the way to go. whether you can get a grip on it while wet is one concern. being junk is a another. polypro (that plastic crap) will get snagged & woven fibers will pull out of it as they snag on everything. whatever you get, go with a tight weave on the outside (keeps it intact & doesn't snag)

a kern mantel, semi static is the best route... something similar to a climbing line or what comes in most throw ropes.

i guess another question is (and i'm assuming this is for kayaking) why would you be carrying around another rope when you have a throw rope in your boat already, that is safely secured in its bag?

for a z-drag kit i carry 2 pulleys, & some biners in my boat plus a throw bag (~50ft), plus a 5mil x 5-6ft climbing line (this i have looped back on itself with two grapevine knots so it loosens/tightens & goes around my waste between my drytop & skirt). this is basically everything you need to set up a quick z-drag & anchor to a tree. (which makes me think, i might need another short sling for looping around a tree (the anchor)

& the mention of "cheaper" probably not an ideal word when used in context with something that could be used to save someone's life.

oops can't find the edit option.... didn't mean to say "best" option.

also, when i did a search of "polypro" lines, ropes like slamkal & I were referring to did come up, but i think most people tend to think of polypro lines as those junkie yellow plastic ropes, only slightly more useful than clothes lines in safety & rescue environments... such as this... Polypropylene Rope - Yellow Floating Line

nathan, we gonna see you up north here any time soon? saw boykin the other day.

Yeah what did you have in mind for runs up there?

Polypro is a common rescue line and happens to be what a lot of throw bags are made out of. Maybe I can just invest in another throw bag and eliminate another rope altogether. I know I need pullies, biners, and some webbing (you want to get some too for anchors). What good is having all the equipment if you don't have an anchor?

Anyways was just scrolling ebay and wondering if I should purchase or not.

Throw bags made of poly are not rescue rope. Some rescue rope is wrapped in poly so that it can be used dual-purpose. I carry a bag with that type of rope on my waist.

Poly stretches and is not suitable for rescue rope. Didn't you get a book with your class? It should have some good rope info, if not there are other good books out there.

As others say, rescue rope is not something to get from anywhere other than a whitewater rescue source. I'm sure there are some exceptions, but unless you are experienced enough to discern the myriad of ropes, stick with what the pros offer.

I can't imagine being glad I saved $50 on rope when my Zdrag fails. Especially if a knucklehead set it up and didn't anchor the rope and it went flying and knocked someone out, or otherwise hurt them. Anytime you are looking for rescue or safety gear, get good stuff. You won't regret it when you use it, and if you never use it you are fortunate.

Quality poly does NOT stretch and in fact it's often a good choice for static line in longer lengths because it's 0% stretch whereas a nylon "static" will still stretch 2-5%. Given, in 75 feet a 5% stretch doesn't mean much. What feels like stretch in a cheap poly rope is just the loose weave. Furthermore, nylon, whether treated or not, absorbs water whereas poly is 100% hydrophobic by virtue of its chemistry. The poly rope in the wet bottom of your boat floats better towards the end of the day than a nylon. That said, most rope manufacturer's use a poly over nylon layup because in tandem you get a nice water resistance to strength to size/weight trade-off.

FWIW, in application, I think the most important thing is length and girth (ladies, do you agree?). You need more rope than 50' when you start z-ing it and those little pinner 1/4" dia. ropes don't hold a friction knot nor any other rope traction device nearly as well as larger diameters. Ditto goes for a swimmer grabbing those skinny lines. If you're really going to use it, and you have a creeker to store it in, then go with 75' by 3/8". IMO, over 3/8" would be sweet, but it just gets too big and heavy to use as a throw rope.

So, does anyone have recommendations (sites) to pick up some good rope? I've also been shopping around and it would be nice to see what others use. Correct me if I'm wrong, but a nylon type rope seems ideal due to the higher melting point and strength. I agree that buying quality rescue gear is important, but I'm also very price conscious. What is a good rope for an affordable price?

Nathan,

i'm mostly clear creek bound, keeping myself in my comfort range until the skills rebound (well that and develop way more than they ever were!).

blue water makes good ropes, you probably chose a suitable rope for your needs. hanging out on the rocks/ice for fun, hanging in trees with sharp objects for work, & now hanging off stacks & towers 100s of feet off the deck, i've never bargain shopped for ropes or safety equipment, but rather bought what i need from a reputable manufacturer who back their gear & labels it.

couple minor items to keep in mind... size your prussic cord accordingly. think it needs to be roughly 1/2 the diameter of the rope it is to grab in order for it to actually grab (verify that factor though)

as your setting up your z-drag, toss a pfd, drybag, or anything easily available over the working end of the rope. that way if it snaps, that item dissipates the energy & can save you or others additional injury.

you can save yourself an anchor sling (simpler is always better) by wrapping the end of rope around a tree (2-3 times dependent upon diameter & bark roughness) & if there is a figure 8 on the rope end clipping it to the line going out.

damn i really need to get out there and practice this again. it's possible to get from deployment to actually pulling on the drag in under a minute... can be a fun competitive game while hanging around camp with your paddling buds.

i'm not certain why the melting point factor is a consideration. if you're paying out rope with a friction device at a rate fast enough to approach melting point, think a rework of the setup is in order. without a friction device, your hands would burn so bad you couldn't use them well before the rope starts to heat up.

more a factor is stretch, hence the semi-static or static recommendations, and a sufficient braiding pattern to keep the rope intact & not having strands pulled out. under high enough strains the cross section of the rope can "collapse", "square out" & get out of round, which can reek havoc on the gripping ability of the prussic.

sorry, hope i'm not rambling :p

For what its worth, I like to cary a couple Petzl Tibloks in my kit to use in stead of prussiks (I have Prussiks, too). They are excellent for Z-drag application, in some cases they can be "self-minding" at the anchor pulley, which is sweet. A jumar is worth it too for the anchor pulley and can be self-minding or as a good handle for pulling. Obviously I am talking about a raft kit, not kayak, tho.

I picked up a new (unused but second hand) NRS z-drag kit so I run their rope for my haul line. This comes with 150' of 1/2" Sterling Static rope, some SMC pulleys, webbing, etc.

In addition I have a pre-rigged 3:1 rope set up that can be prussiked onto the haul line. For this I use 50' of slightly smaller diameter PMI EZ bend 11mm static and more flexible rope from REI at $0.80/foot as this is part of a 3:1 doesn't need the same strength as the haul line since it is under max 1/2 tension and flexibility around the pulleys is more important.

Also the seperate zdrag kit allows me to use the full 150' of the static line without losing length through the z-drag setup ...

Hope I never need to use it ...

i know this thread is a few months old, but.....

i really don't like those tibloks. the teeth seem like they would just wreck the sheath on a rope. i use a ropeman by wildcountry (see here). works greats, feed well. basically the guts of a jumar.

for rope i have 200 feet of bluewater 1/2"/13mm bw-r3 (5,000lbf/22.2 kn tensile strength). i chose that simply because it floats, so less likely to sink & get hung up-one less thing to worry about.

and the anchor that hans mentioned regarding just wrapping the rope several times around a tree and clipping to itself is called a frictionless hitch, if someone was trying to look it up.
