The harder part is completing the recovery after you hace sheared the pin and you haven't got a spare one!
On Fraser Island in 1970 I had to revert to using a steel cable to recover a LWB Station Wagon (with waves washing around it) when my manilla rope broke. I can't remember what size it was, but it was pretty big.
Luckily the shear pin didn't break as the SW was sitting on the chassis.
