Floor Fat Sac Ballast Bag 500 lbs.

FATSAC Floor Fat Sac Ballast Bag 500 lbs.

The FATSAC Floor Fat Sac Ballast Bag is designed to sit on the floor of v-drive wake boats, adding a substantial 500 lbs. of ballast weight to help create a more sizable wake for wakesurfing, hydrofoiling, and wakeboarding. Whether rear lockers are full of gear or you simply need extra weight in the middle of the boat, a floor ballast bag is an ideal portable solution. At 40" x 40" x 8.5", this sac naturally conforms to the available floor space, making it a great fit for smaller v-drive boats.

Thanks to its bulletproof construction using a proprietary layered vinyl material — similar to materials used in river rafts and inflatable boats — you can walk, sit, or stand on the bag without any fear of damage. Each sac is handmade in the USA with strict quality control. Seams are extra-wide, welded, and taped, giving this bag industry-leading strength and durability. FATSAC is the only ballast company that takes the extra step of taping the seams, providing one more layer of protection.

The bag ships with two valves (1 x W730 female quick connect with chain cap, and 1 x W749 air release plug) and uses 3/4" ports for fill and drain. It is designed for use with the Fly High Supa Tsunami Pump (W709-SUPA, sold separately). Custom printing is also available for a fee.

Trusted by world-class athletes and leading boat manufacturers including Nautique, Moomba/Supra, and Malibu/Axis, FATSAC has long been the pioneer in wake ballast innovation and is considered the original wake ballast company.
