Abstract: An improved boat anchor assembly including an anchor shank having a pair of penetrating flukes pivotally connected thereto and supported for angular displacement about an axis normally related to the longitudinal axis of the shank, motion limiting stops mounted on the shank for arresting pivotal motion of the flukes relative to the shank, said shank being provided with a pivotal coupling interposed between the ends thereof and a shear pin for imparting stability to the shank and adapted to give way under angularly applied loads of predetermined magnitudes whereby the shank is permitted to "break" for facilitating recovery of the anchor, and releasable coupling means including a single non-load bearing pin for releasably locking said flukes and said shanks into an integral configuration whereby the anchor readily may be disassembled for compact storage.
