The grapnel anchor is a compact and versatile anchor commonly used for small boats, dinghies, kayaks, and fishing vessels. It features multiple tines or prongs that dig into rocky, weedy, or coral-covered seabeds, making it ideal for areas where traditional fluke anchors struggle to hold. The grapnel anchor is lightweight and often foldable, making it easy to store and deploy. However, its holding power is generally lower in soft sand or mud, as the prongs may not penetrate deeply enough. It is best suited for temporary anchoring, such as securing a boat while fishing or docking for short periods. Proper retrieval techniques, including using a trip line, can help prevent it from getting stuck in rocky terrain.
