The Craz started in '16 and all of the hulls are the same. No changes. The surf tabs evolved a bit but nothing drastic. 16 and 17 had options for how much factory ballast (the upgraded ballast in those models is called "surf edition"). From 18 up they all come with 3000lbs ballast standard. They still need more in my opinion.

The bigger differences are:
17 - autowake introduced (computer controls ballast levels to maintain a specific pitch and roll ideal for the watersport of your choice)

18 - significant autowake enhancement, g6 ballast optional (6 pumps fill and drain much faster enabling surf side changes more quickly and really helps autowake to work well by speeding its adjustment). I also think this was the first year for gatorstep flooring options.

19 - better vinyl (in my opinion), new dash, larger screen. More options standard.
