The opposite of "afloat" is "adrift" or "sunk." While "afloat" suggests being on the surface of water or buoyant, "adrift" implies a lack of control or direction, and "sunk" indicates being submerged below the surface. In a broader context, "grounded" can also serve as an opposite, indicating stability and being fixed in place.
