Hi folks, I dont know jack about ribs but I do know about skiing. You need a mirror and an observer, driving is no big deal just dont run em over, circle around the person in the water to bring em the rope,again don't run em over. to the feller who's daughter is trying to learn , tell her to bring both knees up to her chest put both arms around her knees while holding the rope hold the ski tips just out of the water and when the boat pulls dont try to stand up untill you have cleared the water let the boat do the work. its a lot easier if some one is in the water with the beginner to help steady her while getting ready to be pulled. have fun and be safe Stray Cat
