What is the Splash Zone? The “Splash Zone” refers to the specific area of the hull extending 1 to 3 meters above the waterline. It is defined by continuous alternating wetting and drying caused by wave action and spray. (Note: Higher dry areas around 6–10 meters above the water are classified as topsides, where marine life cannot survive).
Why Biofouling Thrives Here: This constant shift between water and air creates a highly oxygenated, sunlit environment. It acts as a prime breeding ground for marine life, leading to the dense barnacle clusters often seen right along the waterline.
