Line repair

[rjack]

Well, I'd be very surprised if Danny went over it, because I think every word Danny said in that class is burned into my brain. I still hear his voice when I'm cave diving: "The time to switch to a different kick is BEFORE you hit something!"

Melody and I were with Chris and it was discussed and demoed on land once. I have also seen Fred explain the same scenario to a different C1 class, so I really doubt Danny didn't cover it since its a key element of finding your way out if there's a line break on the exit side of the cave.

The suggested method was as you were shown, tie an overhand loop in the cut end of the permanent line. Now you can pass the loop at the end of your spool through that new lop and girth hitch your spool on. Reel(spool) out to the other end of the break. You've got a 150ft safety spool to find it with...

Once the end of the permanent line is re-found, tie an overhand loop in that big enough to pass your spool through. Pass your spool through that loop and pull. This functions like a trucker's hitch to restore tension to the broken ends (something you can't do with a fisherman's knot). After restoring tension, you can tie a series of half hitches using your spool around the repair section. Then lastly cut your spool free.

That's one of the advantages of a Blake's hitch - it's easy to tie, but holds tension like a prusik knot, so you can tie it on the line, then pull the broken end of the line, until you have the desired tension plus a few inches more to give you the slack to tie that half of a fisherman's knot. You end up with half the fisherman's knot butted up against and stopping the fairly similar but slightly longer Blake's hitch, giving you a permanent repair thats a lot cleaner than a loop, a truckers hitch and several half hitches.

At the level this was taught at, making a "good enough" repair was the key part. Not making it pretty. Obviously if you want to make something pretty you can back up to a tie off, cut the line and tie off the loose end at the tie off. Then lay new line identical to the existing line size and knotting frequency to the next tie off and make a clean connection without any obvious intermediate knots or changes in line size/style/color/type/knotting.

I don't disagree with the good enough aspect of it.

I'm just suggesting that with a very simple and easy to tie knot you can make a "good enough" repair that also facilitates making the permanent repair much easier. So if a diver has to learn to do it, why not teach a method that makes the eventual repair much easier, cleaner and more efficient - short of undertaking major line re-laying - and has the benefit of simple very easy to tie in the dark knots.

Richard, that's what Ela did. It seemed like an efficient and effective way to go about the repair.

I'm going to ask Kirk and Gunnar if they remember being taught this. I absolutely do not recall it at all.

For an emergency repair, any knot you know how to make will suffice. An old saying, "if you can't tie a knot, tie a lot".

Thank you Forrest! You made me laugh out loud.

No worries, maybe it was one of those things buried in the shuffle. I just remember it because it was part of our dry land lost line drill. Ie. you have the cave side of the line, but no continous line to exit on anymore. Finding the exit side and (time permitting) patching it is how I recall it being explained. We didn't do it in the water since that would have required willingly diving without a continuous guideline, although I suppose it could have been demoed in open water.

the way mike did it was to put the non-participants for the moment on the line, then take the participant off to the side a bit and tie off, tie them in, and tie off again. then he turned out the light & that was the 'go' signal. that way there wasn't a disruption to the 'real' line.

This how some do it make of it what you will horses for courses and all that.

It is nice, but probably would need to be translated into "American"
