Florida's climate consist of natural causes of wear and tear to the bungee cords. Sun, salt, and water, reduce their ability to hold your canopy firmly on the structure during high winds and boat rides. We highly recommend changing your bungee cords every three years to keep your boat safe in this season’s high winds. While our covers are waterproof, flame, mildew, stain, and dirt resistant, it is important to practice routine maintenance to keep your cover performing to its max.
