Abstract

An improved anchor having a shank and, pivotally connected thereto, a head consisting of a generally flat, arcuate body, a pair of flukes attached to the body and extending laterally from a plane of the shank and body, and a bottom penetrating nose portion, has the further features of the body and shank having a narrowed lead edge and the material of the shank and body being disposed in rectangular cross-sections having substantial ratios of height to thickness. The shank and body of the anchor thereby have a thin lead edge profile to facilitate passage of the anchor through a bottom surface to burrow into the bottom, and the shank has broad side surfaces to resist anchor dislodgement under side forces.
