Scale 1:48. A plan showing the body, sheer lines with outboard detail and longitudinal half-breadth of an unnamed three-masted, 143ft merchant ship pierced for 52 guns and of about 800 tons burden.

A late 20th Century note on the reverse of the plan suggests this may be an East Indiaman. While this interpretation is supported by the hull form, cargo capacity and heavy armament, there is no evidence on the drawing to confirm it.
