Quick Answer
Securing a tarp at its corners is crucial to prevent wind-driven rain from entering the shelter. This can be achieved by using the "tarp tensioning" method or the "anchor" method. The most effective way is to combine both methods for maximum stability.
Tarp Tensioning Method
The tarp tensioning method involves tightening the ridgeline and guy lines to create a taught tarp surface. To secure the corners, use 1-2 stakes per corner, depending on the wind direction and tarp size. Drive the stakes 6-8 inches deep into the ground, leaving 1-2 inches of stake exposed for easy removal. Then, tie the corner straps to the stakes using a secure knot, such as the bowline or the truckers hitch. Tighten the straps to create a snug fit, making sure not to overtighten, which can damage the tarp.
Anchor Method
The anchor method involves creating a sturdy anchor point to secure the tarp corner. Dig a shallow trench 6-8 inches deep and 12-18 inches wide, depending on the wind direction and tarp size. Place a large rock or a metal stake in the trench, and then fill it with soil or sand to create a stable anchor point. Tie the corner strap to the anchor using a secure knot, such as the bowline or the truckers hitch. This method is ideal for areas with loose or sandy soil.
Combining Both Methods
For maximum stability, combine both the tarp tensioning and anchor methods. Drive stakes into the ground 6-8 inches deep, and then tie the corner straps to the stakes using a secure knot. Next, create a shallow trench and place a large rock or metal stake in it. Tie the corner strap to the anchor using a secure knot. This setup will provide a stable and wind-resistant corner point for your tarp shelter.
