Airhead Booster Ball Towable Tube Rope Performance Ball - Booster Ball is designed to make your towable tubing experience even easier. Modeled after an inflatable buoy, this ball has a tow rope connected to both ends. This design helps keep the rope elevated, which boosts visibility. Why else should you love this towable tube accessory? It increases tube performance, too: the ball acts like a shock absorber that minimizes drag and enhances your boat's fuel economy. Plus, it reduces rope spray for a more seamless ride. Another reason to use this inflatable tow rope ball is that it can extend the life of your towable. The simple, yet effective design reduces stress on the tube and its cover, helping it deliver fun and action for years to come. It also ensures that the tow rope is less likely to get caught in the wake, which helps it stay stronger, for longer.
