A grapnel anchor is a type of anchor designed to hold a boat in place by snagging onto the seabed. It typically has multiple flukes or prongs that can catch on rocks, coral, or other underwater structures, providing a secure hold. This makes it particularly useful for small boats or in shallow waters where traditional anchors may not be as effective. Grapnel anchors are often used in activities like fishing or kayaking, where quick deployment and retrieval are important. They are lightweight and easy to handle, making them a popular choice for recreational boaters who need a reliable anchoring solution.
