It makes perfect sense to me Doug <img src="/forums/images/graemlins/smile.gif" alt="" />. Let's see if this does:

If you are winching your own vehicle, the weight you are pulling will be the same weight carried by the line, no mater what snatch block configuration you use. Since it's the fixed end of the line running through the block, and it does not move through the block.

If your vehicle is stationary, you could, concevibaly, connect the snatch block to the vehicle being winched. That should cut the force carried by the line in half.

Force=Mass x Acceleration

You would be moving the vehicle at half the speed you're pulling in line.

Now, I have never seen a snatch block attached to a vehicle, so I'm not recomending it. But, conceptually it would work. But then again, it's early, and it's been a while since physics class <img src="/forums/images/graemlins/scared.gif" alt="" />
