This is an offset from another drawing, rubbed on the back of the paper and well worked up with graphite. An offset was a method used by the van de Veldes to transfer the outline of a ship’s hull from an existing drawing onto a new piece of paper. The new piece of paper was placed over the original drawing and rubbed on the back producing a faint drawing which could be worked up with graphite or pen and ink and any additional detail added.

The flagship is shown port broadside and flies a flag at the foremast. The drawing is unsigned.
