The Simple Trainer offers almost guaranteed success for first-time skiers. It's soft and cushy and features an inflated seat on the back for your child to relax in between learning sets. The comfortable stirrups are on an inflated floor that absorbs the bumps. It comes complete with two ropes - one for the child and a tow rope for an adult to hold onto from the boat. The trainer will plane off with very little movement. Maximum speed of 8 mph. After use, the Simple Trainer easily deflates for storage. Durable PVC construction. For skiers up to 85 lbs. 48"L X 36"W.
