Anchor
A modern temporary anchor usually has a middle bar called the shank, attached to a flat surface (traditionally called fluke) which holds the seabed. The place where the shank meets the fluke is called the crown, and the shank is usually fitted with a ring or shackle to attach it to the rode (cable, chain, or rope joining the anchor to the boat). Some old anchors have attached to the shank a stock, which is a bar that places the anchor in a certain way when it falls on the seabed. Old anchors are often named "stocked" or "stockless" anchors depending on whether they have this, or not.
