Move WakeBags instead of your friends. Keep your water ballast tanks filled to the maximum. Only move your WakeBags for a clean wave. The dead weight of WakeBags make a big difference when it comes adding extra ballast in your boat. Water ballast will inconsistently weight your boat due to sloshing.
You only need 4 bags set up your wake without moving people. With more bags you get the most out of your boat. Upgrade your standard ballast by adding more wakebags. Go big but be nice to your boat
