Scale: 1:48. Plan showing the inboard profile for Salisbury (1814), Romney (1815), and Isis (cancelled 1816), all 50-gun Fourth Rate, two-deckers. The Isis was lengthened by 11 feet and reduced to a spar deck 58-gun Large Frigate by the time of her launch in 1819, so ultimately was a different design. Alterations were made to the rudder on Salisbury and the bulkheads on Romney.
