Was Abraham Crijnssen the only warship disguised as an island?

Was HNLMS Abraham Crijnssen the only ship disguised as an island or something similar?

Probably not, but she is the clearest and most famous case of a moving warship deliberately presented as an island.

Abraham Crijnssen is the best-known example of a warship disguised as an island, but no second warship using the same disguise is identified. Her distinction is the attempt to pass as a moving island, rather than simply conceal a ship beside one. Duck punts offer a much smaller comparison because they also try to blend into their surroundings. That comparison leaves the claim of uniqueness unresolved.
