Abstract: A floating wave dissipation structure comprising tandem connected floating bodies separated by one or more rigid rods having a pivotally securing mechanism at the connection near the bottom of the body side wherein the structure is floated on the sea so that the tandem connected floating bodies are arranged along the direction of the waves. The length of the body in the direction of travel of the waves is selected so that the wavelength divided by the body length is between 2 and 10 with 2 to 7 providing transmission rates of 50% and below. Advantageously, the structure effectively dissipates waves of short, imtermediate and long wavelengths.
