Abstract
Apparatus for attenuating waves on the surface of a fluid and for providing a protective calm area is provided comprising means (20) for causing the waves to break, means (30) for directing the broken waves to induce a downward flow of surface fluid, means (34) for discharging the downward flow of surface fluid a preselected distance below the surface of the fluid, and means (48,50,60,62,64) for orienting the wave breaking means to provide a preselected orientation of the wave breaking means relative to the resultant flux vector of the energy of the waves. In a particular embodiment, one or more submerged refractive structures (20) each in the form of a dome-shaped shell, are provided to cause the waves to break. Guide vanes (36) direct the broken surface waves into a centrally disposed vertical standpipe (34) where the fluid flows downward and is then discharged at the bottom of the shell. A fin-like member (48) coupled to the shell aligns itself and the shell with the resultant energy flux vector to provide the preselected orientation of the shell.
