An improved wave energy collecting apparatus comprising a frame (1) including at least one hinged (2) vertically tilting or rotating surface (3), such as a barrier in the form of a panel or a sail, for collecting energy from passing wave pressure fronts via a tilting or rotating motion within the frame (1), wherein the hinge (2) is positioned below the surface of the fluid at the trough of the passing waves, said barrier (3) being connected to a device capable of transforming the tilting or rotating motion into different types of energy, wherein the apparatus is located at a depth such that the tilting or rotating barrier (3) breaks the surface of passing waves at the crest of the waves. Such an apparatus may also include vertically positioned side walls (4) for directing the pressure fronts from passing waves towards the tilting barrier (3).
