LPL VALVE SYSTEM    
The easiest and cleanest portable ballast system on the market. The Launch Pad Link (LPL) 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 LPL nozzle is located on both the hose and Uber pump, twisting it into place opens the valve automatically for filling and draining, without spilling water into the boat.
