An anti-fouling protector in the form of flexible envelope complementary to the underwater body of a vessel's hull is negatively buoyant and, when not in use, is stored on the bottom of a mooring slip. The invention includes structural features of the slip for guiding endless ropes fixed to the envelope for raising it around the vessel's underwater body when the vessel is moored in the slip, just before a vessel leaves the slip, lanyards connected to the envelope are detached from the vessel and the envelope sinks to its storage position on the bottom of the slip, where anchored lower rope guides prevent the envelope from being moved away by current.
