Quick Answer
Anchor a tarp against one-sided winds by using a sturdy anchor point, such as a tree or boulder, and securing the tarp with rope or cordage at a 45-degree angle to the wind. This angle helps distribute the force of the wind and prevents the tarp from being ripped or pulled loose.
Choosing the Right Anchor Point
When anchoring a tarp against one-sided winds, the anchor point is crucial. Look for a sturdy tree, rock, or boulder that can withstand the force of the wind and the pull of the tarp. Avoid anchoring to small branches or thin saplings, as they may break under the stress. A good anchor point should be at least 10 feet (3 meters) away from the tarp and at a 45-degree angle to the wind direction.
Securing the Tarp
Once you’ve chosen the right anchor point, it’s time to secure the tarp. Use a sturdy rope or cordage, such as a length of 550 cord or 1/4 inch (6 mm) nylon, to tie the tarp to the anchor point. Make sure the rope is tight and not sagging in the middle. To prevent the tarp from being pulled loose, tie a secondary anchor point to the tarp about 5 feet (1.5 meters) away from the main anchor point. This will help distribute the force of the wind and prevent the tarp from being ripped or pulled loose.
Additional Tips
When anchoring a tarp against one-sided winds, it’s essential to consider the wind direction and speed. Use a windbreak, such as a snowbank or a group of evergreen trees, to block the wind and reduce the force on the tarp. If possible, anchor the tarp to a group of trees or rocks instead of a single anchor point, as this will help distribute the force of the wind more evenly.
