You can buy me a pint if you ever need rescuing mate.👍

 

I don't use a wire core flip line, so if I ever need rescuing you can cut as many ropes as you need to bud ;)

I thought that as well, but if you have a pulley tending you could cut the Prussik but the pulley would jam against the end of your wirecore.

It would be a pickle to release with a body hanging off it.

 

Use a swing cheek pulley

Even with a swing cheek Mark has a point - once prussik is cut, the whole body weight of the person being rescued would potentially be on the pulley, so removing it from the krab (swing cheek or not) would be pretty hard in a rescue situation.

As I understand it, you can do your assessment on whatever system you like (excepting SRT perhaps), as long as it's industry recognised/approved.

 

They'll want you to demonstrate knowledge/competence on a basic system though.

 

 

That's how it should be.

 

I know of one chap in his assessment who was asked to demonstrate climbing using one piece of rope (tying a blakes with the trailing end of your bowline) having never seen it. Managed to work it out (not sure I would have) but the assessor would have failed him otherwise. Pretty harsh in my book.

Agreed on that one. Got a 12v angle grinder?

Surely if that's on the required criteria it should be taught. If it's not then it shouldn't be used in a failing point.... Either the assessor or instructor needs reassessing....

It's clearly stated in the workbook, page 19 'Three Knot System' quote - a basic set-up allowing access in and out of the tree using the climbing rope only.

 

It illustrates the Bowline/Blakes hitch/Figure 8 stopper knot and also states "your instructor will show you alternative ways of tying the 3 knot system".

 

If it's in the book you need to know it. When I done mine we never climbed on it but were expected to tie it every time we set the rope in the tree before untying and reverting to our preferred set up which basically came down to a split tail with a Blakes Hitch or a Prussik, I think most of us preferred the prussik.
