👉 Boating fluid, also known as marine grease or antifouling liquid, is a specialized lubricant designed to protect boat hulls and other submerged surfaces from damage caused by marine organisms, such as barnacles and algae, which can build up and increase drag. It works by creating a protective barrier that prevents these organisms from adhering to the boat's hull, thus reducing friction and improving fuel efficiency. Additionally, it helps to repel water, reducing the risk of corrosion and ensuring the longevity of the boat's metal components. Boating fluid typically contains biocides to inhibit the growth of marine life and is formulated to be compatible with various materials commonly found in boats, including rubber, plastic, and metal.
