2013 F21 have GSA. Mainly surf regular. Can someone more experienced give me an idea of the best gsa setting, trim tab deployment and weight disribution. Have 2 rear 650 sumo bags and just got a front 300. (Not used yet)

I have the same boat but I don't have GSA, or a trim tab. I use a 1100 lb bag surf side stock tanks full, 450 up front, and drain the non surf side as we go to clean up the wake. Speed is around 11 mph. using a weight up front will give you a longer wave.

 

Hope this helps. Sometimes I don't fill the 1100 lb bag up, it depends on how many people I have in the boat. It just takes some time on the water to get your boat dialed in.
