Abstract (en)
[origin: WO2017042443A1] The present invention relates to an improvement to the hooking of a flat marine anchor to the sea floor by facilitating the tilting of the flukes immediately upon the backward motion of the ship, while maintaining its stability on the bottom. Originally, the weight of the flukes, acting as a pivot with the crown (6) of the flat anchor and resting on the bottom, hooked the anchor by digging into the bottom upon the backward motion of the ship. Depending on the sea bottom type, the opening became unpredictable, since the anchor would slip before opening and the ship would lose precious meters in a rocky area. Moreover, the anchor would tilt upon its side, slip and become unhooked. The device according to the invention overcomes this drawback. It comprises two claws attached to the sides of the flukes or near the crown on the axis of rotation of the flukes. This enables the latter to tilt and immediately hook to the bottom upon the anchor touching the bottom; thus, upon the backward motion of the ship, the anchor is already open and is immediately hooked; this provides additional hooking to the bottom and prevents or slows down the slippage of the anchor on the bottom by means of four hooking points instead of two.
