Easy to use, durable and convenient for creating larger wakes so you can have more fun riding. Ideal for placing at the front of your boat to keep the nose down.

Liquid Force SUMO Ballast System is the fastest filling ballast system in the industry!

Equipping your boat with SUMO Ballast means less time filling and more time riding your massive wake! All of the SUMO Max ballast System is easy to use, durable and convenient. Sumo ballast is designed to work as a plug 'n play option with your factory ballast system or on deck with our high speed SUMO pumps. Available are an extensive selection of ballast bags to fit any boat or budget.

The Sumo Open Bow Bag is designed to sit on top of your bow seats and adds 415 lbs of additional weight to the front of your boat for a longer, cleaner wake.

Every SUMO sac is double welded to ensure a watertight seal. 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.

These are the most flexible, puncture-resistant ballast bags to date. Sumo Sacs are made with a sandwiched, woven polyester core for maximum strength while still remaining flexible enough for storage. Each bag is reinforced both internally and externally with glued and taped seams, creating a nearly indestructible bag.
