Look at this picture of my boat. I think the hull is quite similar to the Baja that you are looking at and that, of course, is the sole determining factor for achievable wake quality. It's 20'?" long w/ an 8'2" beam.
Anyway, the wake on my boat with no extra weight is pretty large...certainly large enough for all your basic inverts and any other trick normally done wake-to-wake. A 750 lb. sack along the back seat improves it considerably. In that configuration, it is knee high with a nice shape...good pop. I think a sack in the ski locker and some more weight up front would make it great.
The wake is a bit wide below 20mph but I usually ride around 22-23 mph w/ 65' of rope. Unless my speedo is off, I think that one might actually have a hard time clearing the wake at 19 mph. The width and steepness would probably require something like a 10 ft. high trajectory to clear it. ...my speedo could easily be off...GPS time?
Of course, you always have to play with the trim on an I/O to optimize the wake. I will also be experimenting with "hydrofoil stabilizers" as a means of acheiving a larger wake at low speeds. I've seen it done with impressive results on an older 18' runabout. We'll see how that goes.
