Quick Answer
Excessive tarp flapping in the wind may be caused by improper tarp size, inadequate staking, or insufficient guying out. A well-secured tarp can help prevent excessive flapping, which can compromise the structural integrity of the shelter. Proper tarp setup is crucial in windy conditions.
Improper Tarp Setup
A common mistake in tarp setup is using a tarp that is too small for the desired shelter area. A good rule of thumb is to choose a tarp with a minimum diameter of 10 feet (3 meters) to ensure adequate coverage and stability. Additionally, the tarp should be oriented to maximize the angle between the wind direction and the tarp’s surface. A 30-40 degree angle can provide the best balance between wind resistance and water runoff.
Inadequate Staking and Guying
Inadequate staking can cause the tarp to flap excessively in the wind. It’s essential to use a sufficient number of stakes, at least 8-10, to secure the tarp to the ground. Make sure the stakes are driven in at an angle to prevent the tarp from sagging. Guying out the tarp, using rope or cordage, can also help to stabilize it in windy conditions. Attach guy lines to the corners of the tarp and anchor them to fixed objects, such as trees or rocks, to keep the tarp taut.
Additional Considerations
When setting up a tarp in windy conditions, consider the direction of the wind and the surrounding terrain. Avoid setting up the tarp in low-lying areas or near obstacles that can create wind funnels. Use a windbreak, such as a snow wall or a row of rocks, to block the wind and reduce the stress on the tarp. If possible, choose a location with some natural shade, such as a group of trees or a rocky outcropping, to reduce the need for a tarp in the first place.
