The design concept, construction, inspection, and evaluation of the copper-hull of Asperida, a sailing ship that showed high resistance to seawater corrosion and biofouling were analyzed. The hull of the sailing ship was inspected in 2004, which showed that the bow was the only area where there were significant weld defects due to gas that was trapped during initial construction. It was also found that the inside of the hull, including the hull plates, ribs, and deck beams showed minimum corrosion despite of not being painted. It was also found that the forward bilge areas were clean, although a moderate and visible amount of brown corrosion film had occurred. The bilge area was also never painted and had no maintenance and had minimum corrosion without any failure. The wetted bottom of the hull also remained without coating and antifouling paint and required little maintenance to resist corrosion after 34 years of exposure to seawater.
