We have surfed as slow as 7 mph. Last week we had a 170 lb rider, ride an old and small prototype knee board at about 7.5 mph. I think that 11 mph sounds a bit fast, 10.5 might be fast for a "rookie". On my boat getting a hard list going is really important and helps to clean up the wake. Put you weight as far out board as possible.
Don't get in a rush to let go of the rope, let it go slack but hold on to it. After you really get the feel of the wake and your board, then try a free ride.
I’ll second Josh’s advice, put weight forward.
