Abstract: A floating breakwater is constructed from a plurality of interconnected modules each having an internal core formed from floatable material and an external sheath formed from settable material. Each module is provided with a pair of oppositely extending flanges which abut the respective flanges of adjacent modules and all of the modules are secured together to define a continuous block by means of front and rear continuous strips which are secured to the modules by means of elongated fasteners. A plurality of finger modules extend outwardly from the continuous block in spaced relation and a continuous finger strip is secured to the outermost end portions of each of the fingers. A beam is secured between each pair of adjacent modules beneath the abutting flanges. Each beam extends outwardly between the spaced apart fingers and is secured to each of the strips to strengthen the floating breakwater.
