This custom tow rope with inflatable buoy in the middle boosts your towable’s performance in many ways. Primarily by keeping the tow rope out of the water the majority of the time while towing.The SportsStuff 4K Booster Ball System replaces traditional towlines with an inflatable “Booster Ball” buoy with sturdy towline rope at both ends. Suitable for use on any boat, but especially good for boats with low transom tow points, the Booster Ball system provides a way to keep the tow rope elevated out of the water during the ride and increases the visibility of the tow line at all times. The increased height of the towline reduces line drag, absorbs shock, and even enhances the boat’s fuel economy. The Booster Ball system is designed to improve your towable’s performance with quicker starts, reduced rope spray, decreased chance that the towable will dive during the ride, and less wear and tear on your actual towable.

Built for long term durability, the Booster Ball inflatable buoy features bright water-sports graphics with a heavy-gauge PVC bladder and a tough nylon cover with double stitching and reinforced stress points. The system is equipped with a patented speed safety valve for quick inflation and deflation and has a self bailing drain vent to prevent the uptake of water. The system measures 60 feet overall, including the Booster Ball, and the tow rope offers 4100-pound break strength for a worry-free performance. Designed for use with one to four-person towables, the 4K Booster Ball System is built for years of fun on the water.

    Made pulling my tubes SO much easier, faster and more comfortable for the rider as well. OK, first of all, I have read a LOT of these reviews that give a person’s opinion, but nothing to really base it on. Such as type of boat, size of engine what your pulling, etc. Some do include it, but most don’t. To just say this is good or bad isn’t enough to make a decision on in my opinion. So, with that said… -2011 Bass Tracker with 60HP engine, not exactly a competition ski boat. Some would say I shouldn’t even be trying to pull anything with this boat. However, it’s the…

    AWESOME PRODUCT!! This ball does exactly what it says it will do, keep the rope up out of the water on boats with low tow points and reduce the water spray in the eyes of the towable riders. It also greatly reduces the chance of submarining the towable, notice I did not say illuminates. Driver and rider experience has a lot to do with submarining too. Perfect and very well made.We tow the Big Mable couch style and chariot style with absolutely no issue (chariot style requires riders to distribute…
