antifouling paint

A worker applies antifouling paint to the hull of a boat.

Definition

Noun: A specialized coating applied to the submerged surfaces of boats and ships to prevent the attachment and growth of aquatic organisms such as barnacles, algae, and mollusks. This paint works by releasing biocides or using a surface texture that makes it difficult for organisms to adhere.
