When we bought Li she had been badly neglected and had been on hard eight years. You can see in the pictures below the terrible mess inside of the hull when I first time took of the floor boards in 2011! After cleaning the hull looked fine. Only the areas where coins, pieces of electric wire, rust from old tools and other harmful trashes had been sitting for decades showed some surface corrosion. So the coin corroding trough aluminium hull is a myth.
