Should I choose a tarp with a built-in groundsheet for stability?

Weighing the Trade-Offs

A tarp with a built-in groundsheet, often referred to as a “plow point” design, can offer several advantages. The extra layer of material can help to reduce water pooling under the tarp, preventing it from slipping or sagging in the wind. This can be particularly important in wet or windy conditions, where a tarp without a built-in groundsheet may be more prone to failure.

Design Considerations

When choosing a tarp with a built-in groundsheet, consider the weight and packability of the design. A heavier tarp may be more stable, but it may also be bulkier and more difficult to transport. Look for designs that use a lightweight yet durable material, such as silnylon or nylon ripstop. Also, consider the size and shape of the tarp: a larger tarp with a built-in groundsheet may provide more stability, but it may also be more difficult to set up and stake down.

Setting Up a Plow Point Tarp

When setting up a tarp with a built-in groundsheet, use a combination of stakes, guylines, and tree anchors to secure the tarp in place. Make sure to stake down the corners and edges of the tarp firmly, using a minimum of two stakes per corner. Consider using a “A-Frame” setup, where the tarp is staked down to the ground and a ridgepole is used to create a stable and waterproof structure. This can help to ensure that the tarp remains secure and stable in windy conditions.
