Abstract: A lift apparatus for transporting a passenger between positions, such as, a swimming pool deck and a swimming pool, includes a boom having a raised position over the deck and a lower position over the pool. A hinge pivotally mounts one end of the boom at an oblique angle to the pool deck so that the boom is movable in an oblique plane between the raised position over the deck and the lower position over the pool. A seat for supporting the passenger is suspended from the other end of the boom and is at a first position above the deck with the boom in the raised position and at a second position below the deck with the boom in the lower position. A motor-driven gear rack is operatively connected with the boom to reversibly move the boom in the oblique plane between the raised and lower positions to move the seat and passenger in an arc between the first position above the deck and the second position below the deck to transport the passenger between the pool deck and the swimming pool.
