A system converts energy of waves into rotational energy, friction, heat, hydrodynamic lift, and drag to extract energy from waves to reduce their amplitudes and increase their periods to reduce destructive effects on shorelines. This also allows sand to move toward land while capturing and depositing land-ward sand and particulate matter from eroding away from the beach. A plurality of cylindrical-shaped turbines or hydro-foils are stacked in water to rotate in response to energy from waves to dissipate wave energy and renourish beaches and shorelines with sand and other particulate matter. Rounded bearing surfaces are in contact with one another for frictionally engaging one another, and a pair of elongate anchoring members embedded in the sea floor hold the turbines or hydro-foils above the sea floor in an aligned stacked relationship via end portions to assure their frictional engagement.
