Abstract
Abstract Parasail launching and retrieving apparatus adapted to be mounted on a vehicle such as a boat having a tower for supporting a rotatable and pivoted main boom and outrigger boom. The outrigger boom supports the parachute when not in flight and the main boom has a line extending along its full length, one end being connected to a powered winch and the other end having a harness for supporting a person desiring to engage in the sport of parasailing. Upon the person being connected to the harness and the boat moving forwardly at a sufficient speed to permit the billowing of the parachute, the line is payed out and the parachute becomes airborne carrying the parasailor. When it is time to retrieve the parachute the winch is energized to reel in the line as the boat speed is progressively decreased until the parachute is in close proximity to the boat. Then the outrigger boom is extended to engage the canopy of the parachute while the person is deposited in the boat and he is then unhooked from the harness.
