Recall if you buy a new boat your only option is ZO and therefore you do not have any speed over water measurement, unless you manually measure speed in water (pitot or paddlewheel) and then adjust your gps speed accordingly.
I strongly disagree. using a 2 mph river current and a course fixed to the river bottom and 34 mph nominal ground speed the skier "sees" the bouys at the speed (same time through the course either direction) however the water feel under the ski will be like 36 upstream and 32 downstream.

The same for wakeboarding or surfing. water ever the current speed will be your plus on minus.
