If your shade sail starts to sag, you can re-tighten it and bring it taught. One way to do this is by using a wire rope that runs through a pocket sewn in the perimeter of your sail. Simply pull the wire rope on each corner until the shade sail retightens and all sagging is removed.
Why do shade sails sag?
Wire rope is an essential part of our shade sails. Without a wire rope around the perimeter, tension applied at each attachment point is not distributed evenly in the sail, creating areas of concentrated stress around the corners. This causes the center to sag and increases the risk of tearing at the corners.
How do I stop water pooling on my shade sail?
Pools of water on any shade sail will shorten its life and you don’t want pooled water on the sail. You can make sure water runs off the shade sail by installing it at an angle. Another way to make water run off the sail is to use a “hypar” twist. Hypar stands for hyperbolic parabaloid.
How tight should a shade sail be?
