Anchor. Implement by which a ship becomes attached to the ground at sea bed, and so rendered stationary. Parts are: shank, arms, flukes, bill (or pea), stock, ring. They fall into three main groups: Admiralty Pattern, Close Stowing, Stockless. The Admiralty Pattern has a stock at right-angles to the arms which causes the anchor to lie so that one of the flukes will bite into the ground. The Close-stowing anchor has a stock in line with the arms, in the Danforth anchor the stock is attached at the same end of the stock as the arms. The Close-stowing and Stockless anchors have tripping palms which cause the flukes to bite into the ground. The Plough, or C.Q.R. anchor, has flukes shaped like a plough-share. Ship's equipment of anchors is laid down by law and is based, primarily, upon her length. The 'Anchors and Chain Cables Act' demands that exhaustive tests be made on ships' anchors. The 'Merchant Shipping Acts' require that every anchor shall be marked, in two places, with name or initials of maker, and shall carry a serial or progressive number.
