Of use to boatowner and boatbuilder alike, giving advice on problem areas such as keel bolts, propeller shafts etc. Knowledge of metal corrosion and its prevention are vital for the safety and integrity of a boat.  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 examined, as are engines, outdrives 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.
