Abstract: The present invention provides a marine anchor that provides a high holding power and allows faster, smoother and more controlled penetration of the anchor in various soil types. The invention includes an anchor with a shank having two, rearwardly diverging legs that are coupled to the top surface of the fluke along two rearwardly diverging lines so that the plate-like legs define a soil passage that diverges rearwardly within all planes that are parallel to the surface of the fluke between the legs. The fluke preferably includes two primary fluke points disposed on either side a central fluke axis and a third fluke point disposed along the central fluke axis to break up the soil passing over the fluke and between the shank legs. The fluke also incorporates a forwardly tapering profile with a ridge aligned with each fluke point, wherein the fluke is also tapered between each ridge so that the side-to-side cross-section of the fluke has multiple hills and valleys therein.
