An armor unit for protecting coastal, river, lake and reservoir banks, shorelines and other structures from the damaging hydrodynamic forces of waves and water currents, is disclosed. The armor unit has a central elongate member and first and second outer elongate members connected with the central elongate member on opposite sides thereof. The first and second outer elongate members have parallel longitudinal axes extending normal to the longitudinal axis of the central elongate member. In a particular embodiment, the elongate members each have an octagonal cross-section decreasing from an intermediate portion toward the opposite ends. When a plurality of structures are interlocked to define a protective array, a high degree of wedging is afforded between the octagonal members. The two dimensional stability of an exemplary array is at least 70.
