The Admiralty Pattern anchor, also known as “Fisherman”, is the most familiar among non-sailors. When an anchor lands on the bottom, it will generally fall over with the arms parallel to the seabed. As a strain comes onto the rope, the stock will dig into the bottom.
As a heraldic symbol, the anchor symbolizes stability -- in its positive aspect of reliability, safety or consistency. An anchor frequently appears on the flags and coats-of-arms of institutions involved with the sea, both naval and commercial, as well as of port cities and seacoast regions and provinces in various countries.
