caption_attribution_description: English: Isis (1819) Scale: 1:48. Plan showing the body plan, sheer lines, and longitudinal half-breadth proposed (and approved) for Isis (1819), as a 50-gun (later 58-gun) 'spar-deck' Large Fourth Rate Frigate rather than the original design of a 50-gun two-decker. The plan includes alterations for her as a frigate. Signed by Joseph Tucker [Surveyor of the Navy, 1813-1831] and Robert Seppings [Surveyor of the Navy, 1813-1832]. ISIS 1819
context_page_description: HMS Isis launched in 1819 was ordered in 1811 as a 50-gun two-decker of the fourth rate Salisbury class, but was redesigned while building, being lengthened on the stocks by 11 feet, and cut down by one deck to produce a spar-deck frigate, that is, to carry extra guns on the spar deck which linked the forecastle to the quarterdeck.
  It was then intended for her to have carried 58 guns as shown in the table, but this weapon 'fit' was amended on 3 June 1823 to complete her as a 50-gun frigate with an unarmed spar deck, and she was later reduced in 1830 to a 44-gun frigate carrying twenty-six 32-pounder guns on the upper deck, twelve more 32-pounder guns on the quarterdeck, and two 32-pounder guns on the forecastle together with two 8-inch shell guns.
