Apparatus for creating a local reduction in wave height

摘要

Apparatus for creating a local reduction in wave height comprises a buoyant or semi buoyant top surface portion (20) with drag inducing elements (26) disposed below said portion. The drag inducing elements (26) may be compressible or inflatable and collapsible. The apparatus is especially suitable for temporary usage at a given site, after which is may be transported to another site or stored. The compressible or collapsible nature of the drag inducing elements (26) facilitates transport and storage by minimising the volume of the apparatus when not in use.
