Abstract: A portable floating wave dissipating device particularly useful when deployed to protect a beach area during storm periods. The device includes (a) a floating platform, (b) a pivotally connected exposed upper water breaking surface which dissipates the visible portions of oncoming waves, and (c) a pivotally connected submerged lower vane breaking the surface which dissipates the sub-surface portions of oncoming waves. The submerged water breaking surface may also include vanes for redirecting sea water flowing therethrough either upwardly or downwardly to enhance movement of subsurface sediment and sand toward the beach area.
