PROBLEM TO BE SOLVED: To provide a reliable single craw anchor for a boat capable of easily housed in a bow roller of a bow, quickly scraping up on the bottom of the sea, preventing from coming off even when the boat is swung by the wind, and surely exhibiting the effect in any postures. SOLUTION: A shank 1 is provided to have a center of earth pressure acting force of a body frame 2 as a base point when the anchor changes the behavior on the bottom of the sea. A hinge 3 having a claw tip as an axial center rotates to a towing direction while inserting a claw tip rib 6 so that a point where the force is applied is always fixed on a blade edge 7 when the flukes 4 and 5 reach the sea bottom. Stabilizers 8 and 9 at left and right support the balance, and a fluke inclined surface and the stabilizer sliding in all directions correct the postures to each other and are always kept horizontal on the bottom of the sea. When the bottom of the sea is uneven or there are any obstacles on the bottom of the sea, the anchor reaches the bottom sideways and the fluke is bent by the hinge in an angle whereby the soil is easily scraped in. Then, the blade edge is made to penetrate into. At the same time, an inclined surface of the stabilizer of which rear side is a lower side runs onto the soil of the bottom of the sea, and the anchor body is raised horizontally and holds.
