Abstract
A hollow fiberglass bulkhead is constructed for submersion in a swimming pool. Two boxes open-top and open-ended are joined, a shelf is added, end supporting hardware is added, a bottom is placed on the box and the ends are closed and the box is then inverted to be installed in the swimming pool. Balsa wood plates provide rigidity and partial flotation while two end rollers prevent the bulkhead from becoming twisted as it is moved along the pool.
