So this summer I sold my '10 tige Z1 and bought a '14 G23. the river we ride/surf has lots of 8-12' ft areas mixed into its 14-18' spots. I can say that in those shallower spots the G surfs much better than the Z which surprised the heck out of me. We test drove a malibu 22MXZ in the same spots and could not get a wake form. I never did compare the draft #s but the shape of the surf portion on the hull for each boat it definitely makes sense the G would surf better than the Z in that shallow water.
So if your worried about your wake I can say on my boats in my river it turned out for the better in the G vs Z, but we also have a 2mph current whipping thru so that may also be a factor. On the Z we could surf down stream on the G we can NOT so that's one place the Z was better.
