Boat anchor

An improved boat anchor assembly, comprising:

• A. a shank having a base end portion and a shaft projected from the base end portion of the shank adapted to have attached to its distal end an anchor line;
• and
• B. a pair of penetrating flukes disposed in a common plane, said shank being pivotally connected to said flukes and supported thereby for limiting pivotal displacement through the plane of the flukes,
• said shank being characterized by motion-arresting means for arresting motion of said shank relative to said flukes at the limits of throw of the shank relative to the flukes, an elongated shaft and means including a shear pin and a load-bearing pin connecting the shaft of the shank to the base end portion thereof, said shear pin being adapted to give way under transverse loading of a preselected magnitude applied to said shaft by an anchor line attached thereto.

An anchor assembly comprising a pair of flukes having portions engageable with each other in an assembled configuration;

• a fastener engaging said portions releasably to capture the flukes in said assembled configuration;
• a shank;
• coupling means for interconnecting the flukes and the shank in the assembled configuration including a tubular member extending about said portions of the flukes in the assembled configuration wherein said flukes are pivotal within the tubular member when in said assembled configuration substantially about a first predetermined axis, said coupling means mounting the shank for pivotal movement about a second predetermined axis substantially parallel to and spaced from the first predetermined axis;
• and means borne by the anchor assembly for limiting said pivotal movement of the flukes to a predetermined range about the first predetermined axis.
