An antiwave bulkhead for use in swimming pools is disclosed which comprises a plurality of separate bulkhead units, each bulkhead unit having a pair of buoyancy tanks secured within them each of which are provided with air supply conduits enabling air to be independently supplied to or independently evacuated from each of the buoyancy tanks. The bulkhead units include an elongated slot in their front walls at pool water level to admit water into the bulkhead units caused by the bow wave of an approaching swimmer and grating at the lower ends of the bulkhead units to displace the excess admitted water.
