Offering 400 pounds of capacity, the Ronix Eight.3 Telescoping bags are one of the fastest ways to increase the ballast in your boat.

The Eight.3 Ronix Telescope Trapezoid 400lb Ballast Bag is designed to fit in the rear compartment of any v-drive boat, and also works great for building a massive wake on the floor of any direct-drive boat. The versatile back fits just about anywhere thanks to its size and shape. The width of the bag tapers from being the widest at the bottom to create a trapezoidal shape, which Ronix coined “anti-roll” technology; This means no more monitoring your bags. Just fill them and leave them. Ronix rethought and redesigned nearly every aspect of the wakeboard ballast bag.

Using the Eight.3 Ronix Telescope System is easy. Fill and drain your new Ronix Telescope bags in a fraction of the time that you're used to with the 3000 GPH or 3700 GPH portable pump options.


To fill, simply connect the male fitting on the end of the hose to the quick fill port on the top of the bag. Don't worry about spilling any water as there's a built-in check valve to eliminate spills even when the bag is overfilled.


To drain, open the telescoping drain tube. Place the pump body into the bag, and the hose end over the edge of the boat. Once your hose is over the edge, turn the pump on to begin draining.


By sourcing a high strength vinyl material, Eight.3 has some of the strongest ballast bag on the market. All seams and inserts are sonic welded to maintain the highest structural integrity.
