Open Bow Triangle Ballast Bag 650 lbs.

FATSAC Open Bow Triangle Ballast Bag 650 lbs.

The FATSAC Open Bow Triangle Ballast Bag is a triangular-shaped ballast sac specifically engineered to fill the open bow area of a wakeboard or wakesurf boat. Placing it up front and filling it delivers a significant improvement in wake transition and density. The triangular shape allows the rider to fine-tune forward and aft weight distribution simply by partially filling the bag. In conjunction with additional weight at the rear, adding 650 lbs to the front of the boat produces a deeper wake with a longer, smoother transition.

The sac can be placed inside a bow compartment or directly on the floor. It is constructed from a proprietary layered vinyl material developed specifically for ballast applications, identical in durability to river raft material. Seams are double-welded and taped for industry-leading strength, meaning you can stand, step, or sit on the sac without concern. The material is also UV stabilized to resist sun damage over time.

Each bag ships complete with all fittings required for use with the FATSAC Supa Tsunami Pump W709-SUPA (pump sold separately): one W730 pump connector, one W749 air release plug, and one W731 wally plug. The bag features three port holes and is compatible with FATSAC automatic ballast systems when additional fittings such as W743-SS or W736-SS are added. Custom printing is available — contact FATSAC at support@fatsac.com for details.
