A supporting frame with netting material is placed around a swimming pool, either an in ground pool or an above ground pool, to at least partially enclose the pool and provide for the attachment and support of sport apparatus such as basketball, aeroball, and/or water polo goals at opposite sides or ends of the pool and such as a volleyball net stretched across the pool. The netting material may extend along the ends of the pool, around the entire periphery of the pool, and, if desired, across the top of the pool. The netting material ensures that lose sport apparatus, such as balls, used with the attached sport apparatus that contacts the netting material remains in the pool. The supporting frame includes support members that are secured to the pool. If the pool is an above ground pool, the support members are secured to the pool structure. The support members may be substantially rigid members or inflatable members.
