Retrievable anchor system

A retrievable anchor system comprising:

• an anchor having a top and a bottom, the anchor comprising an elongated central shank having a top end and a bottom end;
• an elongate flexible member for suspending the anchor from a boat, the flexible member having a base end and a securing end, the base end being substantially permanently fixed to the bottom end of the central shank of the anchor;
• a dual attachment assembly releasably attaching a location on the flexible member to a location on the central shank located toward the top of the anchor, the location on the flexible member being separated from the base end of the flexible member, the dual attachment assembly comprising:
• a primary attachment structure forming a directional attachment between the flexible member and the central shank;
• and
• a secondary attachment structure forming a frangible attachment of the flexible member to the central shank;
• wherein the primary attachment structure comprises a hook element mounted on the central shank towards the top end and configured to engage a portion of the flexible member;
• wherein the hook element is formed by a finger attached to the central shank and extending downwardly and outwardly from the central shank.

A retrievable anchor system comprising:

• an anchor having a top and a bottom, the anchor comprising an elongated central shank having a top end and a bottom end;
• a chain for suspending the anchor from a boat, the chain having a base end and a securing end, the base end being substantially permanently fixed to the bottom end of the central shank of the anchor;
• a dual attachment assembly releasably attaching a location on the chain to a location on the central shank located toward the top of the anchor, the location on the chain being separated from the base end of the chain, the dual attachment assembly comprising:
• a primary attachment structure forming a directional attachment between the chain and the central shank, the primary attachment structure being configured to maintain attachment of the chain to the central shank when the chain is pulled in an upward direction with respect to the central shank, the primary attachment structure being configured to release attachment of the chain to the central shank when the chain is pulled in a downward direction with respect to the central shank;
• and
• a secondary attachment structure forming a frangible attachment of the chain to the central shank, the secondary attachment structure comprising a loop of frangible material extending about a portion of the chain and about the central shank of the anchor;
• wherein the primary attachment structure comprises a hook element mounted on the central shank towards the top end and configured to engage a portion of the chain;
• and
• wherein the hook element opens in a direction toward the bottom end of the central shank to allow the chain to be released from the hook element when the chain is pulled toward the bottom end.
