Straight Line Sumo Max 475 Sac

Compact dimensions still offer adequate weight for many applications with the speed of Sumo Max. The Sumo Max 475 features the same construction and performance as the standard Sumo ballast bags, along with the added speed of the Sumo Max fill port. The 475 ballast bag is a great alternative for those that don't have the locker space to fit larger Sumo Max bags.


  • SUMO Skin 1000D
    SUMO Sacs are made with flexible and puncture-resistant fabric, “SUMO Skin.” It has a durable 1000 Denier polyester core that is heat laminated to lightweight PVC skins with a bonding agent. This sandwich construction is 150% stronger in tearing tests and 37% higher in tensile strength than any other fat sacs out there, making it the most durable ballast bag available.
  • SUMO Seams
    Every SUMO sac is double welded to ensure a watertight seal. The tough SUMO Skin is overlapped and hot air welded. You can see the smooth and clean seams on the outside of every bag, and a second welding operation applies an inch wide sealing tape to the inside of every seam.
    The new SUMO MAX FLOW valve is a new 1 ½ Inch diameter high flow version of the Sumo LINK™ system. The SUMO Max Flow valve provides the same hassle free watertight connection to your Sumo Max Pump but with massive 50% LARGER intake. The Sumo Max system is 100% compatible with the classic Sumo and Big Bag ballast systems.
  • LINK™ Valve
    The unique LINK™ system provides a hassle free connection to your Sumo Pump, keeping your boat dry on the inside. The Link™ Valve is watertight and can also be used as a convenient way to purge air from your bag.
  • 1”NPT Valves
    NEW easy turning cap with a perfect water tight seal. Pressure tested up to 6 PSI. The 1” NPT ports allow built in ballast systems to fill, drain and vent quickly for hassle free operation.
