LINK SYSTEM
The easiest and cleanest portable ballast system on the market. 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.
