Ship armour is to be distinguished from the practice of hull sheathing for preservational reasons, namely the protection against marine wood-boring worms. Greek merchantmen were fitted with lead sheets for that purpose by the 5th century BCE. A notable Roman example were the excavated Nemi Ships with an underwater hull covered by a thin layer of lead. The practice was resumed by the Spanish and Portuguese in the Age of Exploration, while the British Royal Navy began to copper their war ships in the 1760s.
