Wakesurfing just became easier thanks to the FatSac Pro X Series Ultimate Wakesurf Ballast Bag. After filling any factory ballast and fat sac that fill the front and rear compartments of your V-drive boat, put the FatSac Ultimate Wakesurf Sac on top of the rear seat and side seat that you are wake surfing on for the ultimate surf wake. This will displace so much water that people will no longer have to work to wakesurf behind your boat - they will just be able to do it with ease. Be sure to remember to give the boat some throttle to bring the front of your boat up enough when passing thru any wakes you are making so you don’t swamp the boat with the tsunamis you are creating with this sac setup. The FatSac Pro X Series Ultimate Wakesurf will also conform to fit in other type boats and in other places.
