Russians on an anchor

When checking our draft before departure Wilhelmshaven, I saw two Russian A/B's repairing their paint damage probably done by their own anchor. Two details struck me, and those were also the reason I took this picture. First that the A/B's were probably brothers and maybe even twins, and second that there is just as much blue paint on the anchor than on the hull. The anchor is a High Holding Power Pool TW anchor by the way. An improved Pool design, very effectively and very cheap.
