The invention discloses a gravity-buffered boat anchor device, which comprises an anchor body, flukes and an anchor rod, wherein the flukes are hook-shaped, and arranged at the two ends of the anchor body; a cavity structure is embedded in the anchor body; a clamping groove is formed in the anchor rod; the anchor rod is arranged in the centre position of the bottom end of the cavity of the anchor body and upwards extends from the bottom end of the anchor body; a reverse locking device is arranged at the connecting part of the anchor rod and the bottom end of the cavity of the anchor body; the upper surface of the reverse locking device is connected with an impeller; the impeller is connected with the outer side of the anchor rod through clamping blocks in a sleeving manner; and the anchor body comprises a plurality of through hole structures. According to the gravity-buffered boat anchor device, during the anchor dropping process, water enters the cavity through the through hole structures, and the impeller is driven to rotate through buoyancy of the water and gravity of an anchor chain, so that gravity during the anchor dropping process can be buffered, and the fact that the anchor quickly collides with foreign bodies at the seabed is prevented; during anchor weighing, the impellers are impeller is locked by the reverse locking device to stop rotating, and rapid anchor weighing is achieved.
