Floor Fat Sac Ballast Bag 800 lbs.

FATSAC Floor Fat Sac Ballast Bag 800 lbs.

The FATSAC Floor Fat Sac Ballast Bag is a high-performance portable ballast solution designed to sit on the floor of v-drive wake boats, adding 800 lbs. of ballast weight to the center of the boat to help create a more substantial wake for wakesurfing, hydrofoiling, and wakeboarding. At 42" x 40" x 13", this bag is sized to fill just about any floor space available and naturally conforms to the shape of the space — making it a versatile addition to any wake boat setup. When rear lockers are full of gear or you need to redistribute weight, a floor ballast bag is an ideal solution.

Each Floor FatSac is handmade in Milwaukee, Wisconsin, USA to the highest quality and durability standards. The bag is constructed from a proprietary layered vinyl material (Pro X Series Valmex) similar to materials used in river rafts and inflatable boats, making it nearly impossible to puncture. Extra-wide seams are welded and taped — a step unique to FATSAC that adds an extra layer of protection against failure. The bags are UV-stabilized for long-lasting performance in outdoor conditions.

Thanks to this bulletproof construction, you can walk, sit, or step on the bag without any concern for damage — an important feature for bags placed in high-traffic areas of the boat. The bag features two port holes (1 fill/vent, 1 drain) with 3/4" port size, and comes with all the fittings needed for use with the Supa Tsunami pump (W709-SUPA, sold separately), including 1x W730 and 1x W749 valve/cap. Custom printing is also available on request (fees apply).

FATSAC ballast bags are trusted by world-class athletes and leading wake boat manufacturers including Nautique, Moomba/Supra, and Malibu/Axis. If you own a wake boat manufactured in the last decade, chances are it already features a FATSAC bag as OEM ballast — FATSAC is considered the original wake ballast company and a long-time pioneer in the sport.
