I don't know exactly what makes the FS3 different than the previous FS2 but I believe it is a setback pump similar to a 2008 superjet. Despite the "FS" name and it being a lighter layup, the hull design is not what you would consider a flat water ski. It is a pretty long hull, more more suited to rec riding and surf. It would be great if you want to chase boats, do some turns and will flip off of a decent wake/wave but if you are looking for a backflip hull to replace the BOB it is not that (IMO).
