The invention discloses a buoyancy-adjustable boat anchor which comprises an anchor body and an anchor rod, wherein the upper surface of the anchor body is in a rectangular shape; the front surface and back surface of the anchor body are in triangular shapes; the left side surface and the right side surface of the anchor body are in trapezoid shapes; a cavity is formed in the anchor body; water inlets are formed in the upper surface of the anchor body; water outlet valves are arranged on the left side surface, the right side surface, the front surface and the back surface; opening stay cords are arranged on the water outlet valves; the anchor rod is arranged in the center of the upper surface of the anchor body; and the top end of the anchor rod is connected with a lifting ring of an anchor chain. According to the buoyancy-adjustable boat anchor, during anchor dropping, the anchor can be quickly fixed in silt due to the shape and structure of the anchor, and meanwhile, water enters the cavity; and during anchor weighing, the buoyancy of the boat anchor can be controlled through the water outlet valves to realize quick anchor weighing.
