No scale. Plan shows the sketch of sails, as fitted for the Pearl class corvette Pearl (1855). A note on the drawing states that copies of this plan were sent to Woolwich on 5 April 1855 for the building of Pearl (1855), to Plymouth on 4 May 1855 for the building of the sister ship Satellite (1855), to Sheerness on 4 July 1855 for the building of the sister ship Scylla (1856) and to Chatham on 12 October 1855 for the building of the sister ship Cadmus (1856). This plan is in need of conservation.
