How Custom Fit Ballast Bags Work
Custom-fit ballast bags are shaped to fit specific compartments on specific boats rather than the rectangular or cylindrical shape of standard bags. They maximize the amount of weight you can fit into a ski locker, trunk, or under-seat storage area, which means more ballast in the same footprint compared to standard Fat Sacs. For boats where space limits how much standard ballast you can carry, custom-fit bags are often the difference between an acceptable surf wave and a great one.
Custom Fit Ballast Bags by Boat Brand
Our custom-fit ballast bag collection includes Wakemakers Plug-and-Play bags and other brand-specific options sized to fit Malibu, Mastercraft, Centurion, Tige, Supra, Axis, Moomba, and other inboard wake boat compartments. Call us at (309) 371-0095 if you want to confirm which bag fits your specific boat year and model. We've been fitting ballast bags to specific makes and models since 2007.
