As for your question about "don't you need a Winch to use a snatch block?"
NO! I just need a rope. The longer the rope the better. The longer the rope the easier it will be for me be cause of two things.
1) The longer the rope the farther I can reach an anchor point.
2) The longer the rope the more snatch blocks I can use in the system..
