Bottom, Outer

The outer bottom of a ship is the part of the hull that is below the waterline and is in contact with the water. It is the part of the ship that is most exposed to the harsh marine environment and is therefore subject to corrosion, fouling, and damage from impacts with floating objects. The outer bottom is typically coated with antifouling paint to prevent the growth of marine organisms and with protective coatings to prevent corrosion. Regular inspection and maintenance of the outer bottom are essential to ensure the safety and seaworthiness of the vessel.
