Scale 1:96. Plan showing an incomplete plan of middle deck, lower deck, and orlop deck for 'Blenheim' (1709), a 90-gun Second Rate, three-decker, as converted to a hospital ship. 'Blenheim' was converted to an hospital ship in 1740 until 1747, and later reclassed as an hospital ship in 1755. It is likely that the plan refers to her original conversion.

This plan is incomplete because the top sheet has been removed; it would have held the plans for the quarterdeck and forecastle, the upper deck, as well as the port side of the middle deck.
