  • Patent number: 5207531
    Abstract: The present invention is an artificial surfing reef for modifying near shore ocean floor bottom to create surfing waves. The artificial surfing reef is a generally Y-shaped structure made of many large sized polyvinyl chloride pipes and having a leading leg and two main legs joined at a joint, where the leading leg extends from the joint toward the offshore direction. As a swell moves toward the shore, its bottom is resisted by the leading leg of the artificial surfing reef, and its top topples over the joint and is tapered by the two main legs of the artificial surfing reef to thereby form perfect surfing waves.
