Graduated Bar Scale. Plan showing the body plan, sheer lines with inboard detail, and longitudinal half-breadth for an unnamed Spanish 112-gun three-decker. Spain built a number of 112-gun warships of which five were built at Ferrol, where Julian Martin de Retamosa was the shipbuilder. These included the 'Purisma Concepcion', 'San Jose' (1783), 'Santa Ana', 'Salvador del Mundo' (1787), and 'Reina Luisa'. It is possible that this plan was never approved or used to construct a 112-gun three-decker.
