Contenido:

Metal corrosion and its prevention are often considered black arts and yet knowledge of both are vital for the safety and integrity of a boat. Failure through corrosion or fatigue can result in masts falling down, keels falling off or boats quietly sinking at their moorings. Less dramatic are such problems as pitting or fracturing of propeller shafts, erosion of pipe work, rusting of steel hulls and galvanic corrosion of aluminium ones.

The third edition of this book is for boat owner and boat builder alike, giving advice on how to prevent or at least reduce the corrosive effects of seawater. In this edition more attention is paid to electrolytic corrosion as nowadays many more people plug into a shore supply. Modern super sealants, copper sheathing and chromium plating are also examined, as are engines, sterndrives and even mooring chains since these are just as vital to a boat´s security as the rudder stock. Finally, there are tables showing the corrosion rates of different metals in fresh and salt water.
