I teach a simple rule for retrieving a vehicle bogged in sand: The slowest recovery is usually the fastest, because it works right the first time.
Time after time I watch people mildly bogged in sand get out the MaxTrax (or whatever traction boards they have), dig a peremptory trench in front of the sunken tires, cram the board in, and give it the beans, which results in nothing but the tires digging in deeper because they aren’t actually in contact with the board. Or, worse, the tire will be barely on the edge, and the spinning tread will fail to catch but will melt off the first row of spikes on the board, even alloy versions. The vehicle is now stuck worse than before and the expensive traction boards are damaged.
This won’t work.
The tire is not in contact with the board. It will only sink farther.
Don’t do it that way. Take the time to fully dig out in front of the tire, enough so the traction board makes full contact. If possible you want the trench dug out so far that the tire wants to roll down onto the board. And make sure the trench has the gentlest possible slope. Don’t do what one poor fellow I watched did and scoop out all the sand into a nice little mound in front of the trench, right where the tire needed to go.
This will work. Board in firm contact with the tire, and a gentle ramp to climb.
If you’re solo and need to keep moving once you’re free, don’t forget to put the shovel back in the vehicle, and leash the traction boards to your rear bumper so they’ll follow you like obedient dogs until it’s safe to stop.
Americans always seem to be embarrassed by getting stuck, when in fact it’s a normal part of exploration. Adopt the attitude of my British friends, who use the mildest bogging as an excuse to take a break and brew some tea.
