Beach Slackline

At the end of the summer, I had the chance to set up my slackline on the beach. Apart from being in the sand and by the water, the main difference was the anchors. Usually, a slackline is attached to a tree or something of that shape, and as a result, takes just a few minutes to set up. To anchor the line on a beach, you have to dig two large holes, each three feet deep, four feet wide, and one foot long. The ends of the slackline each go around a 4x10 board that is four feet long and then lowered into the hole and buried. To hold the line off the ground, I made my own A-frames, which support my weight, as well as share the tension load (as much as 5000 lbs.) with the ground anchors. The result provides for a very strong system that can hold up against bounces and jumps. The only issue is the time it takes to measure out and dig the holes. I think it took me somewhere around 45 minutes to dig and rebury each board. However, if you’ve never done it before, it's worth it, as I was able to use the line all day, even at 11:00 during a bonfire.
