Product Description
More weight in the rear means a bigger wake and a better surf wave. This bag drops directly into your factory ballast system — no custom plumbing, no rewiring. It fills and drains automatically using your existing dash switches, just like stock, but with significantly more capacity.
Built in Chandler, Arizona and backed by a 2-year warranty. Most orders ship within 48–72 hours.
Each bag comes with male quick release 1 1/8” fittings to connect to your existing female quick release hose ends. If your boat requires different fittings, browse our fittings here.
Details: MADE TO ORDER WHEN ORDERED, EXPECT 2 WEEKS
These are BAGS ONLY! - Be sure to add the correct 1 1/8" or 3/4" fittings. The ports in the bags we make are 1" female threaded ports that fit FatSac part # W743 or # W742. These fittings will thread into the bag on one end and the other end will seal to your quick release connections at the end of your hose.
These Double Decker bags can integrate with the hard tanks below your rear lockers to increase the overall capacity of your factory ballast system and produce a bigger wake while keeping the convenience of controlling all ballast with the switches at your dash. The ballast bags included in your Double Decker system can be integrated into your boat's existing ballast system for automated filling/draining. These are BAGS ONLY!
The rear zone of the boat is the most important spot for additional weight, helping to increase the size of your Nautique's wake. Depending on the year and model Nautique you have, this will increase the capacity of your ballast system from 250 lbs to 1,700 lbs per side!
Every Double Decker system is designed to be a user-friendly DIY install that can be completed in your garage over the course of an afternoon, or by your local boat mechanic.
Be sure to add to your order any parts you need to install the double decker bags to your existing system such as extra hose, clamps or fittings for your current hose size.
