Proper maintenance of an inflatable rubber boat is essential for its longevity. After each use, rinse the boat with fresh water to remove salt, sand, and debris. Avoid prolonged exposure to direct sunlight, as it can cause material degradation. Regularly inspect the boat for any signs of wear, tears, or leaks and promptly repair them with appropriate patch kits. Store the boat in a cool, dry place and release excess air when not in use.
