Artificial reef

An artificial reef is a man made reef, usually built for the purpose of promoting marine life. Ships are often scuttled to create artificial reefs, but a large variety of objects including structures purposely built for use as reefs can be used. More recently, reefs have been created for surfing specific purposes, with the worlds first reef at Cables in Western Australia. This reef was constructed of large granite rocks in an 'A' frame shape to form an appropriate breaking wave that would suit surfers.
