Mariner Knot

Postby Hann » Thu Nov 11, 2010 2:42 pm

Sometimes in climbing one makes use of prussics.
Often it becomes an issue to untie the prussic because it is being loaded.

A great knot to know is the Mariner Knot.
The cool thing is that it can be untied while under load.

So when used in conjunction with a prussic it may just be a handy piece of knowledge.

The image shows a cordelette, but it works with a sling too.

THIS KNOT NEEDS TO BE BACKED UP

Nice one Hann.

You can also use the French Prussic (below) which can be released under load.
Its a simple wrap around the rope and clip both ends into a biner.

This is a useful knot to use for hauling/locking off and safe guarding yourself during abseils.

Hey Justin....

Good luck opening the biner and getting the loop out of the gate while loaded :afro:

(Perhaps I'm speaking a little to quickly.... perhaps I should actually try the french prussic tonight)

I agree with you Hann...
The French Prussic is more of a 'personal' use knot whereas the Mariner Knot is something you might use during a team rescue!?

When taking a load with the French Prussic, I'm assuming you have a belay device of sort above it it.
Let me know how you get on :)
