In a series of recent papers it has been suggested that shore platforms are best developed at mid-tide level because tidal duration is greatest in this zone and, hence, beach processes operate for a proportionately longer time there. The present short paper demonstrates that, in fact, maximum tidal duration is associated with high- and low-water zones rather than with mid-tide level. Since tidal level varies most rapidly at the mid-tide position wave action is least effective there. The implications of this are briefly considered.
