Abstract: An anchor of the twin fluke type in which crown members attached to the flukes support transverse restraining bars adapted to limit swing of the shank out of the plane of the flukes. One end of each restraining bar is pivotally connected to its respective crown member, and the other end is engaged by a locking member when the bar is in transverse restraining position. A release line connected to each locking member extends substantially coextensively with the anchoring line and is adapted to be pulled to remove the locking member from whichever restraining bar is engaging the shank, thereby permitting the restraining bar to pivot out of restraining position and permitting the shank to swing up to 180.degree. from the plane of the flukes so that the anchor can be pulled clear of obstructions.

Abstract: An anchor raising device and method of raising an anchor in which the device has a tubular body that is readily opened and closed so it may be applied quickly and easily to an anchor line when it is necessary to raise the anchor on the anchor line and is able to be readily removed from the anchor line once the anchor is raised and its purpose has been accomplished.
