Abstract
A marine anchor comprises a fluke with a shank attached to the fluke to enable the anchor to be joined to an anchor cable. Additionally there is provided a soil barrier plate located aft of the rear of the fluke but above the level of the fluke, with a soil passage between the barrier plate and the fluke. The barrier plate is set an angle to the fluke, and the barrier plate and the associated soil passage are arranged so as to function in a manner enabling the anchor to operate effectively and without adjustment in cohesive soils such as mud even when the fluke is set (say at an attack angle 0.degree. of 30.degree.) for optimum operation in non-cohesive soils such as sand, without substantially detracting from the performance of the anchor in non-cohesive (sand) soils.
