उत्तर
This statement is True.
Explanation:
While ships are painted to protect them from the harsh marine environment, they can still suffer damage. The paint acts as a protective layer against corrosion caused by water, salt and marine organisms, but over time, the paint can wear off due to factors like weathering, abrasion and biofouling. Therefore, despite being painted, ships may still experience damage to their hulls and other parts.
