New owner here. Our local tri-lakes area does a little summer program teaching kids to ski and wakeboard. My 13 year skis and my 10 year old does everything (ski, slalom, kneeboard, wakeboard, wakeskate, etc). So once the kids learn to ski well they get to start to learn to climb. This was my 10 year old's first shoulder ride attempt this summer. I think she pulled it off pretty well.
Note this should not be tried without proper gear and more importantly proper training. Our lake association fortunately has professionals that have taught these kinds of maneuvers for decades and they know what they are doing. Note that my daughter is not using a ski rope but using a "bridal." A ski rope for that position is VERY dangerous because the climber could get caught in a normal ski rope.
