The Straight Line Big Bag 800 Single adds up to 800 pounds of ballast to your wakeboard or waterski boat.
Heavy duty 30 Gauge PVC // Strong, electronically welded seams // One Link valve for clean filling/draining Weight label around valve for easy size identification // Color coded graphics for ideal boat location recommendations Three 1" standard pipe thread valves for easy custom installation The easiest and cleanest portable ballast system on the market.
The Link System
The Link system uses a spring-loaded valve on the bag to create an air and water-tight seal, even when the cap is off! It's easy to use because a Link nozzle is located on both the hose and Sumo pump, twisting it into place opens the valve automatically for filling and draining, without spilling water into the boat.
