Abstract A water ski aid for supporting a water skier includes an inflatable seat member. A pair of inflatable arms is used to secure the skier to the inflatable seat member. The free ends of the arms overlap the body of the skier when in a secure position in the seat member. The arms separate when the skier gains sufficient speed to overcome the drag of the inflatable seat member.
