This is certainly the component that has the shortest life. The cause lies in the materials used. A sail is subject to many different factors of wear. Let us know and reduce the damage.
When the sun set the wind without hope that the dates and Riggi is already dry, do not cook further monofilm leading to the sun - if possible - your shade sail. WARNING: The "cooking" is the primary cause of aging because of the sail makes the monofilm fragile.
Abrasion. The base of the wing is "grating" on the table. With a good break, you can slip some of the seams and the monofilm scratch in less than a season. In the loft are excellent remedies cheap: you want over a broken machine the seams of the base and ask to apply the adhesive material for protection. You can see an example of this application in the wing used in the photo beside. Strongly advise you to disregard the question: you have this traction exerted by the downhaul?
Arming and disarming with strong wind. For arm: roll out the sail and put out the tree. You must have the wind behind. Avoid absolutely lay immediately across the sail and make it fly and try to put the tree! Every lash of monofilm heard that at least creates a fold dry, and also happens with the new sails!
Transport. Not wring your sails on the roof with the straps! Unfortunately, the transportation is a thorny issue or put in the car for long (if you are traveling alone) or arranged with a beautiful travel bag that, apart from making a flight case for airline travel, allowing you to cram 2-3 trees, 2-3 sails a boom and the table ... all with only two straps! With this accessory you spare several minutes to upload and download, also. Some, especially the campers, are built using container of water in plastic pipes with threaded caps on the ends. The "tubone" remains fixed to the medium and extracting only the sailing. Personally I gave up when I saw the cost of materials.
Conservation. After the last board in the water, supported the sail out of the sand and let dry. Alternatively, if you have a sufficiently heavy table, you can ensure that the remains Riggi made with thanks to the weight of the hull. If the type of holiday gives you the opportunity, pass the equipment under a shower or use the sound of dry water. If you can not do this, rinse the sails at home: equipment remains wet salted forever and aging very quickly. When you finally put your sail, arrotolatela carefully trying to do a roll tight enough to prevent the folds between adjacent layers.
