A wave attenuator structure for dissipation of wave energy of a body of water is described. The structure preferably is equipped with a substantially horizontal base, a foot extending substantially vertically downward from the base, and a wall extending substantially vertically upward from the base. The wall forms a water-facing face, which face slopes in the direction of the body of water. The wall and the base define a plurality of channels sized and configured to receive one or more respective anchor devices for anchoring the wave attenuator structure in soil.
