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.
