- Warranty Policy: South Atlantic systems are warranted for three years from the date of purchase by the original owner against defects in materials and workmanship.
- Material Guarantee: In addition to the three-year warranty, a lifetime guarantee applies specifically to the raw materials and structural components. It does not cover normal wear-and-tear items, such as control lines or vanes, nor damage resulting from neglect, misuse, or improper handling.
