EFFECTS OF FOULING AND ITS ECONOMIC IMPORTANCE: PART 2

Last month the author considered the effects of fouling on harbour installations and power stations after briefly surveying the history of measures taken to prevent it. This month, emphasis is on ships. Satisfactory anti‐corrosive and anti‐fouling compositions, properly applied, have an important beneficial effect on the frictional resistance, and without sufficient precaution, fouling and corrosion of a ship's hull eventually often add over 20% to the resistance of a new ship.
