I don't want to be picky but.........
the method that Andrews is describing is infact a kinetic recovery. The fact that the ropes stretches mean that energy will be stored in the rope and released when the vehicle comes unstcuk. What people normally understand as a kinetic recovery is the same except that the speed, loads & engery release is much greater. Some times too much for the hard ware & that is when you get bits flying off all over the place.
Take care, be safe, be sensible and keep your heads down.

This is why I said gently drive off, the reason for this is to keep a little momentum up with the recovering vehicle, the ropes described are not designed as a kinetic rope so don't 'twang' back like a kinetic rope would, they stretch a little and don't have any re-coil.
As I said it works for me and I have never experienced re-coil from these ropes.
Each to their own devices eh  In the Beginning there was nothing, which exploded.

Andrew, appreciate your comments.
The point I was trying to get across was that "kinetic" recovery is some times frowned upon because of the potential for damage & injury, where as I believe it has a place in our arsenal of tools for recovery when used correctly.
I would also say that I have not done a proper "kinetic recovery few some years as there has been no need. Other methods have proved more appropriate, i.e. winch or tow.
The 3 strand nylon ropes in the pictures above are good bits of kit and indeed I used them for years before there was an alternative.
As some one else said earlier there is moeny to be paid & choices to be made.
Regards

Believe me it was not a nice experience when the rope launches you under extreme acceleration towards the recovering vehicle  and personally I don’t think the single point recovery eye on a D3 is strong enough for a kinetic rope recovery.
I witnessed that, it was what I would describe as a 'snatch' recovery and was done with no regard for the vehicle being pulled, I always thought with a kinetic rope you took up the strain and let the recoil on the rope do most of the work, not drive balls out and keep going which looked just plain dangerous to me  The End

I have been looking for shackles at companies specialised in industrial lifting and when studying their offers, I had a look at their hooks.
The ropes I ordered just have eyes, no hooks. The ones on the pictures on the forum do have hooks at both ends.
But looking at an industrial 4T hook, you are speaking about a +/-25cm long hook of about 4kg...
Interesting...
Let's rather not break our heads about it and use what we've got.
