Scale 1:48. A plan showing a body plan with half-stern board, sheer lines, and longitudinal half-breadth for a 206ft, 90-gun, Second Rate, two-decker designed by Captain Armar L. Corry of 'Superb' (1842), and based on experience from the Experimental Cruise of Evolution in late 1847. This seems to be based on the design for 'Rodney' (1833). The plan is accompanied by a letter of calculations on two pages. It seems this design was not used.
