The Hydroslide Power Ball is designed to keep the tow rope out of the water for better performance on turns, slides, and a overall better ride. Keeping more rope out of the water reduces drag and helps absorb shock for easier towing and it provides better control for the boat driver. Plus, easier towing means better gas performance. The Power Ball is great for boats that tow off the transom. Includes 60' of 4,000-lb. rated tow rope.
