So, I've been thinking about recovery options and the like, and have come up with an idea I'd like to run out.

Insteadof a winch * (or incase of winch failure) , or come along, or equiv. How about X amount of wire rope (or synthetic), shackles (2 or 3), a snatch block, and 1 or 2 non-stuck vehicles.

Idea being to effect a recovery much like pulling a mountaineer out of a glacial crevase.

1. Attach rope/cable to non-stuck vehicle (if you have 2 non stuck vehicles), or other suitable anchor (boulder/tree/whatever).
2. Run cable/rope to stuck vehicle, pass through snatch block and back out to pulling vehicle.
3. Attach to recovery point and gently pull cable/rope tight (and hopefully stuck vehicle out).

Obviously this is situation/location dependant, as there are times/places that the rigging just wont work. Also, if you had enough shackles & cable/rope you could bump this up to a full "Z drag" system.

Any thoughts?
