V-drive boat captains running heavy stern tanks often deal with a steep, washed-out wave lip, but the FatSac 800# Floor Ballast Bag solves this weight balancing issue instantly. FatSac engineered this high-volume square bladder to sit squarely on the center cabin floor, countering heavy rear placement by pushing the nose down. Adding 800 lbs of raw water weight lengthens your wakesurf wave pocket while stretching out wakeboarding transition lines perfectly. The extra heavy-duty square construction handles regular passenger foot traffic without dropping internal pressure. Every run grows longer. Pocket tracking stays locked.

The defensive build utilizes commercial-grade layered UV-stabilized polyvinyl material paired with high-frequency welded seams that never split from sudden hull slams. Pressure-taped burst-proof seams ensure maximum material security, allowing your crew to walk, step, or sit on the bladder during rough lake runs. Captains building automated plumbing lines cross-reference these inset valves with fittings in our specialized boat wakeboard package sets lineup to optimize flow. In-house CNC machined fittings handle high-speed pump hoses.

Maximum Center Floor Balancing & Hull Plane Control

This 800 lbs center floor bag functions as the ultimate solution for large V-drive boats that suffer from massive bow rise and slow planing times. Forcing the belly of the craft deeper into the water column flattens out the tracking plane, letting you shape clean surf waves.

We verified this 800 lbs floor sac performance on a high-output V-drive boat. The CNC machined fittings locked tight with our Supa Tsunami pump, filling the massive 96-gallon chamber in just a few minutes with zero line leakage. Placing this weight in the cabin center instantly flattened our tracking, making the wave pocket incredibly long.

Why Choose FatSac 800# Floor Ballast Bag

Standard cheap water bags expand into round, unstable logs that slide across the deck, bruising ankles and risking seam ruptures during sharp turns. The FatSac 800# bag prevents this hazard by packing high-volume square stabilization and welded burst-proof layers together, providing a long-term commercial investment that keeps your crew safe.

Factory Warranty & Professional Care Guidelines

This maximum capacity floor sac comes backed by an official 1 Year Limited Manufacturer Warranty covering structural flaws. To protect the UV-stabilized polyvinyl from chemical rot or sun baking, clear off fuel fumes and lake muck after use. Store the bladder completely dry inside a dark locker.
