His primary (if not sole) focus should be getting across the wake without fear and with speed, angle, and body position (@markn photo). Won’t matter how wide he starts, he will loose all the width after a few balls if he can’t get across the wake properly. When he is not able to ski the course he should ditch the turns and just practice getting across the wake. A while back, @RobHazelwood posted a video on working up to a full speed wake crossing which could be beneficial.
