JRscooby, I have a raised receiver hitch so the rack is about 14" off the ground. The pictures don't show it but my HR really isn't that tall. The tops of the kayaks are about 12' off the ground.
Good to know you are aware. 14 inches that far behind the axles does not sound like a lot of clearance to me, but it works for you.
I just wanted to point out there is a limit to how long of boat can be hauled vertically, in case somebody copied your idea without thought.
I have no dog in the race, as much trouble as I have standing up off the floor, the fun would end with wet.
