How many types of anchors are there?

There are several types of anchors, but they can generally be categorized into three main types: fixed anchors, which are permanently attached to a structure or the seabed; mobile anchors, which can be repositioned as needed; and temporary anchors, used for short-term applications. Within these categories, there are various designs such as screw anchors, grapnel anchors, and fluke anchors, each suited for specific conditions and applications. The choice of anchor depends on factors like the environment, load requirements, and intended use.
