Common Question of FatSac 750
What capacity does this FatSac have?
The FatSac Gray High Flow bag has a listed capacity of 750 pounds. Its ballast capacity can increase boat displacement when installed correctly, affecting wake shape and size. Confirm compartment dimensions, fittings, pump compatibility, hose routing, and boat manufacturer limits before using the 750-pound ballast bag.
What does High Flow indicate?
High Flow identifies the bag’s fitting or ballast-system configuration intended to support faster filling and draining with compatible equipment. Actual flow depends on pump capacity, hose diameter, fittings, and electrical supply. Verify the complete system before relying on High Flow ballast performance.
How does ballast affect wakes?
Ballast changes boat weight distribution and can influence wake size, shape, and riding characteristics. Distribute weight safely and avoid exceeding the vessel’s capacity or affecting visibility and handling. Follow FatSac and boat guidance for controlled wake-shaping ballast use.
