ABSTRACT:
A wave suppression device, for use in suppressing large waves formed by ships, tides and wind and for use in harbor and marina areas and the demarcation of swimming areas, comprised of a cylindrical core having a plurality of fins radially extending from its outer surface. The fins are positioned substantially coextensively along the length of the core. Two disc members are circumferentially positioned substantially perpendicular about and connected to each end of the core member and fins. An opening in the core provides a means for introducing water to the hollow interior area of the assembly to provide a desired buoyancy, which opening interacts with a plug top provide a water-tight seal. The flotation assembly includes a central axial opening for receiving a cable or like device for stringing a plurality of wave suppression devices together to form a lane demarcation. A tube is located within this central axial opening, and the end of this opening contain threaded areas for receiving a bushing which secures the tube within this opening and can also secure the assembly to the cable or like stringing device.
