FATSAC Fat Seat Ballast Bag - 1,250 Lbs - Gray


Description

The FATSAC Fat Seat is one of the original ballast bags, purpose-built to transform your boat's wake into a surf-worthy wall of water. Its patented U-shape is designed to fit snugly around a direct drive engine compartment, taking the place of a removable rear seat or sitting on top of it - wherever you have space. Engineered to add 1,100 pounds of ballast, the Fat Seat delivers the deep, powerful wakes that wake surfers demand. Constructed to handle real-world punishment, it can be sat on, stepped on, and used just like a standard back seat without compromising performance. With six port holes for flexible plumbing configurations and included fittings for the Supa Pump, it integrates cleanly into your existing ballast setup. Whether you're running an inboard ski boat or a dedicated surf rig, the Fat Seat is a trusted name in ballast that's stood the test of time.


Key Features

  • Patented U-Shape Design: Fits around a direct drive engine compartment, replacing or sitting atop the rear seat in boats with removable seats.
  • 1,100 Lbs of Ballast: Adds serious weight to create a deeper, more powerful wake surf wake behind inboard boats.
  • Durable Construction: Built to be sat on and stepped on - tough enough to serve as a functional rear seat when filled.
  • 6 Port Holes: Multiple plumbing holes allow for flexible hose routing and pump connection configurations.
  • Supa Pump Ready: Includes fittings to connect directly to the FATSAC Supa Pump (S7090, sold separately) for fast fill and drain.
  • Dimensions - 63" W x 42" L x 12" H: Body measures 63" W x 29" L x 12" H; each arm extends 22" L x 13" W x 12" H.
  • Multiple Fit Options: Can be used in place of a rear seat or placed on top - versatile placement wherever you have room.
  • Included Hardware: Comes with 1 W730 pump connector, 4 W731 plugs, and 1 W749 air release valve.
  • Wake Surf Optimized: Designed specifically to generate wake surf-quality wakes from your inboard boat.

FAQ

Does the pump come included with the Fat Seat?

No, the Supa Pump (S7090) is sold separately. However, the Fat Seat includes the necessary fittings - a W730 pump connector, four W731 plugs, and a W749 air release valve - so it's ready to connect to the Supa Pump right out of the box.

Will the Fat Seat fit my boat?

The Fat Seat is designed for inboard boats with a removable rear seat or boats with a direct drive engine compartment. It can sit in place of the rear seat or on top of it. The overall dimensions are 63" wide x 42" long x 12" tall, so measure your available space before ordering. Contact us at service@omahasportsandgames.com if you'd like help confirming fitment for your specific boat.

Can you actually sit on the Fat Seat when it's full?

Yes! One of the standout features of the Fat Seat is that it's built to be sat on, stepped on, and used just like a regular back seat. You don't have to work around it - it functions as a practical seating surface while delivering full ballast performance.

How do I fill and drain the Fat Seat?

The Fat Seat fills and drains using the FATSAC Supa Pump (W710 is compatible with S7090, sold separately). The bag features 6 port holes for flexible plumbing configurations. Connect the pump using the included W730 pump connector and use the W749 air release valve to vent air during filling.

What kind of wake does the Fat Seat create?

Adding 1,100 lbs of ballast with the Fat Seat creates a significantly deeper and more powerful wake - ideal for wake surfing. The extra weight pushes the stern lower in the water, generating a longer, steeper wave that surfers can ride without a rope.
