Winch & Recovery Sizing

How hard your winch has to pull to get you out, what a double or triple line does, and what your winch, its drum and its battery go through on the way. With a source for every number.

Set up your recovery on the pictures: type on the vehicle, the winch and the rope, pick the ground, drag the slope. Everything updates as you go.
