Anchor Matrosov - one of the types of anchors with high holding capacity. Invented in 1946 by Soviet engineer I. Matrosov.
Design and Function
The anchor acts on the principle of the Hall anchor , but is largely spared from its shortcomings. The paws of Matrosov’s anchor are brought together and a streamlined shape is given to the entire anchor, which allows it to go deeper into the ground. To give the anchor stability on the outer edges of the paws, tides (outgrowths) with flanges at the ends were made. The anchor enters the ground according to the principle of a crank mechanism : the spindle rotates relative to the lateral tides so that when the anchor chain is pulled, it acts as a connecting rod, turning the arm paws along the axis of rotation. Matrosov’s anchor quickly enters the ground (“picks up”) and does not leave it when the ship turns 360 degrees. The holding force of this anchor is more than four times that of an admiralty anchor of the same weight. It reliably holds the ship on a weak sandy-silty and is very stable on hard, fine-rocky soil. Found wide application in the river fleet. It can be performed both cast and welded.
