hulk

A hulk is a ship that is afloat, but incapable of going to sea. Although sometimes used to describe a ship that has been launched but not completed, the term most often refers to an old ship that has had its rigging and/or internal equipment removed, retaining only its flotational qualities. The term "hulk" can also be used to refer to an abandoned wreck or shell.

Originally, a hulk (sometimes spelled "holk") was a type of medieval sea craft somewhat similar to a cog and a technological precedent of the carrack and caravel.
