FatSac Open Bow Triangle Ballast
Counterbalancing heavy stern ballast, the FatSac open-bow triangle sac provides 650 pounds of walkable water weight to fit center floor footwells of open-bow boats.
- Triangular profile fits open-bow floors
- Walkable construction withstands foot traffic
- Adds 650 pounds of counterweight
- Three valve ports enable rapid filling
Severe bow rise often blocks your forward line of sight when accelerating hard, but the FatSac Open Bow Triangle Ballast provides the perfect technical solution to neutralize heavy stern weight. FatSac engineered this specialized low-profile triangular profile bladder to sit flush inside the open-bow floor footwell area without stealing passenger legroom. Pushing 650 lbs of raw water displacement weight into the nose forces the hull to track flat, stretching out your wakesurf wave pocket. The forward leveling keeps wakeboarding launch lines incredibly long and clean. Wave height peaks beautifully.
This commercial marine-grade skin uses proprietary, layered UV-stabilized Valmex polyvinyl fabric that easily withstands heavy foot traffic scuffs and raw fiberglass rubbing. High-frequency welded and seam-taped connections prevent sudden burst fractures, allowing your crew to safely walk or sit directly on the bag during operation. Captains upgrading their integrated plumbing lines cross-reference these inset ports with setups in our boat wakeboard package sets collection to optimize pump speeds. Three valve ports handle rapid water movement.
Why Choose FatSac Open Bow Triangle Ballast
Standard square bags slide across bow decks, block seat access, and pop along the corners when the hull hits heavy lake chop, dumping hundreds of gallons inside your stringers. The FatSac Triangle sac avoids this safety hazard by packing low-profile floor stabilization and walkable Valmex layers together, providing a long-term commercial investment.
Factory Warranty & Professional Care Guidelines
FatSac backs this model with an official 1 Year Limited Manufacturer Warranty against factory bonding failures. To protect the high-frequency welded seams and prevent internal mildew rot, always evacuate water completely before long-term winter storage. Keep sharp loose anchors out of the bow footwell area.
