Z-drag setup

Just wondering about other opinions on this.

What do you have in your z-drag kit?
Hope long of a rope and what kind of rope do you carry?
Where do you store your z-drag kit on the boat?
How much webbing do you have?

I have a minimal z-drag kit on my stern in a bag. I currently have (copied from NRS):

4-Omega Locking D 'Biners
2-SMC rescue Pulleys
2-15' sections of 1" webbing in red
2-15' sections of 1" webbing in green
4-6' prusik cords (7 mm)

Don't have a rope yet.

70' spectra rope bag around my waist
2 lockers
2 cmc pulleys
3 prussiks
3' piece of webbing with another locker for an anchor point

This is in my green jacket. I'm a kayaker though.

I feel like 70 feet of rope would not be enough to set up a z-drag on many rivers (but haven't actually done it, so take that for what it's worth).

Common wisdom for rafting calls for 150 ft of rope, but it occured to me that 2x75 feet sections might work just as well. 1 rope run straight to the anchor and tied off, and the other 2nd rope tied to the same anchor and used to set up the z.

This would allow 2 spectra bags to funciton as both throw bags in swimmer rescue scenarios, and used together to become a z-drag. It also has the added benefit of not all the ropes being kept in the same place, so you're more likely to still have 1 rope if something happens with the second rope.

Thoughts?

I think in streetdoctor case he is a kayaker and 70' is plenty for the stuff he is running (mostly smaller rivers).

150' is what my buddy carries on his raft and I always relied on his rope if we ever had to use it, since he is always on my trips.

I have 100' bow line in a bag and 75' stern line in a bag as well, that I plan to use with a z-drag if I need to.

So I agree with you on splitting the rope, then you don't put all your eggs in one basket in case the boat that is carrying everything gets pinned.

cupido, where do you carry your kit in the boat?

I carry 75' 10mm static line, 4 lockers, 2 prusicks, 2 20' sections of webbing, a 15' cordolette (sp?), 2 pulleys in the bottom of my drybox.
to date, I have never seen a z drag do more that waste valuable time and cause some very amusing discussion as greenies (my self included) go through all the different anchor points and methods (or lack there of). Get more people, unload what you need to, and flip it by hand. You will need to re-rig anyway onless you run a tighter/cleaner rig than anything I have ever seen!

HA! So true, I haven't seen one deployed in real life situation yet either, only during the rescue class. But it's like flipping your boat... you either have or will flip, there is no "IF". So eventually someone in your group is going to pin good and hard enough and your shiny z-drag skills will come in use.

I like to be over prepared for any situation and love to talk gear and browse amazon.com for deals

I keep the ascenders from my mountaineering days in my kit. Prusiks are a pia when put under mucho weight.

I'm actually still in the process of deciding what to buy because I don't have an ideal rope yet... and I just thought of this double-rope idea the other day.

I have about 75 feet of rope on the bow (thought I'm honestly not sure if it's strong enough to withstand the forces of a z-drag), and don't usually carry a stern rope. I have my slings, pulleys, and biners in a waterproof "fanny pack" that I wear all the time. I have cheap throw bags, but I think I'll buy a 75 foot sprectra bag that I can attach with a quick-release belt.

Most decent throw ropes have a breaking point of around 1500-1600 lbs. The static ropes for z-drag on nrsweb.org for example has a breaking point of 4000-5000 lbs. In a pinch, throw/bow ropes would work, but having a good rope in one of the boats might be helpful.

Yep, and if I'm running anything bigger or with more risk I have a spare rope bag I'll keep in my boat. Between what's on me and everyone else in my party having a rope bag I don't think it's an issue. I've went back and forth between carrying an extra prussik/carabiner/pulley incase a 3:1 wasn't enough (theoretically of course) but I've never seen or heard of anyone using a 3:1 for a kayak so I haven't bothered. I am kind of a rope nerd though...
