A structure for dissipating the energy of waves impinging on a shore is disclosed which comprises one or more rows of mo- dules (10) positioned adjacent the shore. Each module incorporates a number of vanes (49, 49', 49", 126). The vanes are shaped and spaced so that a number of venturi passages (94) are defined between the vanes. Each vane has a frontal portion (49, 68', 68") which faces away from the shore, and is inclined from the vertical so that it slopes away from the shore to define an entrapment chamber (96, 96', 96") which forces an oncoming wave to pass through the venturi passages rather than over the module or be ref- lected. The sides (80) of the passages converge from front to back. A longitudinally extending hub (50) causes the passages to converge also in the vertical direction. Each vane may be X-shaped and substantially symmetrical about a vertical plane through its centre. The modules are cast from a cementitious material and may incorporate a number of the vanes joined together at the hub which is located at the centre of the X. The vanes may be joined together at their upper and lower ends by cross members (28, 30, 32, 34, 128, 130, 156, 158). The passages may incorporate cross vanes (106) which divide the passage into sub-passages. Other vane shapes are disclosed. The vanes may be individually fabricated.
