Yes; yes, they are. Why would anyone pack ropes in the wrong order?

If I have three or four bags going on one trip, I get very confused as to what ropes are where and the only way I can remember what order the sacks need to be used in is by putting on hauling cords in alphabetical order of colour i.e. bag 1 = black, bag 2 = blue, bag 3 = purple, bag 4 = yellow.
If I didn't do this and I didn't label my ropes, I wouldn't have a clue!

There's sometimes a point in packing bags in an interleaved order where bag/carrier numbers are low and the pitch lengths don't conveniently fit capacities if done in-order. That still requires that you know the necessary pitch lengths in order to work out what to do, but having length information on the ropes does at least give more information for little obvious cost.

There can also be the "Which is the next bag?" situation, assuming caves that require multiple bags, and length markers can help in that.

In any case, even if someone tried to only have ropes of lengths 12.5*2^n metres, ropes can easily end up being cut at some point due to wear, ending up outside the scheme, and given that necessary rope lengths vary hugely, if on a proper vertical trip, it can save a lot of rope if a good spread of lengths is available.

If ropes are going to be marked anyway, (which is useful for someone who caves (or even shares a hut) with other people who have ropes, and for identifying ropes on multiply-rigged pitches, etc) there seems no obvious reason not to stick a length on them.

On multi-bag trips I use the krabs as my code D, H, O (alpha code), similarly.

Entirely agree. However, the OP seemed to infer marking one's own ropes - and my contention is that one person can own a lot of rope bundles before finding that they need to mark the lengths on them (e.g. I've got 16 and know the lengths of all of them without needing to write it down).

Well, I don't have a huge number, but even though I know what I have, I'd still need to mark at least some, since there are some similar-but-different lengths of the same kind of rope.

Interesting. At the risk of hijacking the thread, anybody have any other methods?

I take it this means, Cap 'n Chris, that you label your krabs but not your ropes? I guess it's easier to lose a krab .. but I just use electrical tape rather than bothering with letters. I guess you use yours professionally, though.

Cover the end of rope with insulation tape with kit colours, and then write the length on the tape with marker pen? Then heatshrink to finish so it doesn't fall off.
Isn't that standard procedure for most club ropes?
Now, who reckons the glue from the tape will do some damage?

D-shape, HMS, Oval. No marking required. The krabs are clipped to the bags.

Damage to the last inch of rope?
In any case, personally, I write on coloured heatshrink, then shrink it on the rope and cover with clear.

Which then pulls off in the rope washer  :(

I've heard of heatshrink catching in a P-hanger and preventing a pull-through; I don't know if it's true but this could be serious for someone who had not taken the precaution of having a spare rope.

Depends somewhat on how well it's shrunk on, and what the rope washer's like.
The rope washer I use, there's no obvious advantage to pulling the rope end through rather than unloading it from the scrubbers first - it cleans right up to the entry point, so not pulling through only ends up with the last few inches being unscrubbed.

sadly some of us live in clubs that have odd rope lengths like 60m which is quite hard to tell from 50m.
Also when visiting a popular cave, it helps if you can tell which rope is yours
And we can track rope usage and retirement ages
And we can chop 5m off the end of a 50m rope without ending up with a rope we think is 50m when its actually 45m

Er, just don't mark the length of your rope. Simple.

I've never needed to (so far), since all my bundles of rope are obvious, i.e. 12m, 25m, 50m, 100m.

Unless you have several ropes of the same length, bought at different times...

My Club numbers each rope individually and records date of purchase etc. (I think Pitlamp is familiar with the story of an old Orpheus rope found in Peak Cavern's Far Sump Extensions, whose age we were able to determine due to this system of labelling and recording ...).

Also, for one reason or another, some of our ropes are of similar lengths visually while coiled up in the tackle store but can be very different in actual length (say 30m vs 45m) so rope labelling does have its place.

I'm not a complete idiot: some parts are missing!

What if someone in your team decide that the HMS is in fact a Pear-Shape?  :o

That's assuming there is a team. Maybe he's just 'ard.

I stopped pulling new rope through a descender, just wears it out when you could do that in a cave.

DHO is for solos (I can't carry more than three bags anyhoo); if there's other people along then it's easier since we just use their kit bags (mine are all blue so I need a system to keep tabs on them) - if the bags are different colours it's easy to remember which order to use them in and is a better visual method of telling.

They should have said, marker pens have been found to degrade rope strength. best not use it. try tags or heatshrink...

Plus if your marker is on the last 5cm of rope... What the hell are you doing on that bit anyway!!! Other then falling off the end because you forgot the knot.

"Before the first use, soak a static rope in water for 24 hours.
This creates a better bond between the sheath and the core and helps remove lubricants
(particularly slippery) used during manufacture.
Let the rope dry slowly. It will shrink by approximately 5 % (5 m for every 100 m). Take
this into account in calculating the required length. A well-used rope can shrink up to an
additional 5 %." Petzl (Tips for maintaining your equipment)

Hi Larry,
