A marine anchor (1) has an anhedral fluke (2) with a shank (3) attached thereto including an anchor line attachment point (10). A rear plate assembly (4) behind the fluke (2) is inclined at an obtuse angle (.alpha.) to the fluke (2) and serves to provide a turning moment about the attachment point (10) countering turning moments produced by friction effect on the fluke and the shank and by edge resistance during anchor burial to give improved anchor holding power while soil escapes passage (5) between the rear assembly (4) and the fluke (2) allows escape of sand and soft mud passing over the fluke. Peripheral edges (4A) of the rear assembly (4) are shaped to cause rolling of the anchor to a burial position. An upturned toe portion (9) at the front of the fluke encourages effective anchor operation in clay soils while also facilitating rock gripping by the anchor.
