Abstract: Anchor fluke, being formed as to have a penetration or front-side and a rear side, as well as a longitudinal plane of symmetry intersecting these sides, the anchor fluke comprising first device for attachment of an anchor line for use in a vertical anchoring system and a second device for attachment of at least two connecting lines spaced in the longitudianl plane of symmetry so as to connect the fluke to a pulling or penetration anchor line, the fluke being so formed that at least its upper surface has a shape convexly curved or buckled in cross-section along the plane of symmetry, the first attachment device for the anchor line for a vertical anchoring system being located near the center of area of the fluke.

Abstract: An anchor comprising a fluke means with upper surfaces having a center of area and a front end or penetration end and a rear end, and a shank means, being connected at a first end to the fluke means and, being provided at a second end with first means for attachment to an anchor or pulling line, said shank means being attached by means of at least one hinged joint to the fluke means at a location at a distance of the center of area, and being attached by means of a disconnectable connection to the fluke means in a location on the other side of the center of area with respect to the hinged joint, said hinged joint being located at a location towards the front at a distance of the center of area and operating means being present for effectuating the disconnection of the disconnectable connection by remote control.
