A fluke anchor is a type of anchor commonly used in boating and sailing. It features two flat, triangular flukes that dig into the seabed when deployed, providing a strong hold. This design allows the anchor to set quickly and resist being pulled out by wind or current, making it effective for various seabed conditions. Fluke anchors are often made from materials like steel or aluminum and come in various sizes to suit different vessels. They are particularly popular for smaller boats and recreational crafts due to their lightweight nature and ease of handling.
