Thanks very much for all the feedback and ideas. Much to consider as I try and put this thing together…
Seems that the general concensus is that more of everything and longer lengths will help me to be more prepared. With that in mind, here’s what I’m “hearing” and where I’m at now…along with a few more questions:
1) Get the proper training & practice using it before you really need it
– Agreed, point taken-
2) Add More Webbing In Varying Lengths
- –10’/15’/20’/25’ sections REI - $24
3) More Carabiners Will Be Useful In A Complex Setup
– Agreed, I’m adding 3 that will always stay with the kit REI -$ ( I always have more in my PFD and elsewhere in the boat)
4) Go with 3 or 4 pulleys
– Makes sense, will add a few
5) More Prussik Cord in longer /varying lengths
6) Add Basic Climbing Gear
- (I have a harness, ATC, Fig8 that will go in the kit)
7) Get A Longer Rope
– Sounds like I’m seeing 200’ as a good length for most kits people mention on the Buzz. I understand though that more is always better if you have the budget/space or are primarily on larger rivers where a wrap could occur farther from the shore. Will look at 200’+ for the kit.
Consider the Need For Alternate Anchoring
- It sounds like climbing nuts/cams would be a good addition, just in case. As I don’t do much climbing, any particular sizes to get or ideas for this? Craigslist might be suitable for used/good condition gear here.
9) Pulley Strength
- I noticed a comment that any pulleys over 20kn (~4500 lbs) should be sufficient but more is better. Thoughts on this? Does it make sense to mix and match…say 1 of the nicer 2” SMC Swiftwaters (34kn) with 2 of the SMC CRs (22kn) ?
10) Rope Strength
– Many comments mentioning the use of Spectra. It seems to me for the main purpose of a raft z-drag, the tensile strength of the rope would be the main consideration, correct? If so, Spectra appears to be just over 5k lbs tensile strength. In comparison, the Sterling rope seems to be pretty much top-of-the –line with tensile strength of over 9k lbs. With the 20% member deal REI has going now, 200’ of the 11mm PMI rescue line (~6100lbs tensile strength) would go for 64 cents/ft or $128. I just wonder if that line is a good performance/value option? Maybe I’m missing something though.
Admittedly, I’m far from a physics major…guess those last two questions on pulley/rope strength might be directed at anyone who has a better grasp on the forces involved than I do. For those interested this article was interesting and seemingly on-topic, http://www.whitewater-rescue.com/sup...tunpinning.pdf
I’m all for getting quality equipment and having the right tool for the job, but at the same time with a z-drag kit, I am trying to weigh the cost of the kit with likelihood that it ever comes out of the dry bag and goes into use. Suppose it is kind of like insurance in that regard, you hope you never need to use it.
