What is an shank in anchor?

In the context of an anchor, the shank refers to the long, straight part that connects the anchor's flukes (the arms that dig into the seabed) to the crown (the top part where the anchor chain or rope attaches). The shank provides leverage when the anchor is set, helping to keep it securely embedded in the seabed. Its design and length can affect the anchor's holding power and stability in various marine environments.
