The wave-power system may comprise a floating body structure, a set of blades attached to the floating body structure, a weight assembly, a bidirectional to unidirectional shaft assembly and/or a power unit. The weight assembly may comprise a plurality of weights which may rotate around a first axis of rotation as a result of floating movements of the floating body structure. Rotation of the plurality of weights may cause an input shaft of the bidirectional to unidirectional shaft assembly to rotate. An output shaft of the bidirectional to unidirectional shaft assembly may rotate in a first direction, regardless of a direction of rotation of the input shaft. Rotation of the output shaft causes the power unit to produce the electric power. ## Claims ### Claim 1 A wave-power system configured to produce electric power, comprising: a floating body structure;
