The invention discloses a boat anchor used for buffering the gravity. The boat anchor comprises an anchor body, anchor palms and an anchor rod, wherein the anchor palms are in the shape of hooks and are arranged at two ends of the anchor body; a clamping groove is formed in the outer side of the anchor rod,; the anchor rod is arranged in the middle part of a cavity of the anchor body, and extends upwards along the bottom end of the anchor body; impellers are arranged in the cavity of the anchor body; opposite locking devices are connected to the top ends of the impellers; the impellers and the opposite locking devices are connected to the outer side of the anchor rod in a sleeving manner; the opposite locking devices are fixed to the anchor rod through limit blocks; and the anchor body comprises a plurality of through hole structures. According to the boat anchor used for buffering the gravity, in the process of casting the anchor, water enters the cavity through the through hole structures, the impellers are driven to rotate by means of the buoyancy of water and the gravity of an anchor chain, the gravity in the process of casting the anchor can be buffered, the anchor is prevented from colliding with foreign objects under the sea, and when the anchor is pulled up, the impellers are locked by the opposite locking devices to stop rotating, and thus the anchor is pulled up rapidly.
