Scale: 1:48. A block design model of the ‘Princess Mary’ (1742), a 60-gun, two-decker, third rate ship of the line. The name ‘Princess Mary’ appears on the starboard broadside and ‘Princess Mary built at Portsmouth 1737’ is on the stern.

Commissioned under the 1733 Establishment, the ‘Princess Mary’ was both larger (at 144 feet by 40 feet) and heavier (at 1060 tons burden) than the 60-gun ships of the 1719 Establishment. The gun arrangement remained at twenty-four 24-pound guns on the gun deck, twenty-six 9-pounders on the upper deck, eight 6-pounders on the quarterdeck and two 6-pounders on the forecastle. Four hundred men would have served on a ship of this type.

The ‘Princess Mary’ was launched in October 1742 to 1733 Establishment specifications, shortly before the ‘60s’ were increased in size and re-classed as ‘fourth rates’ by the 1741 Establishment. Its first service was in the Channel in 1743, and it was in Balchen’s fleet in 1744. It spent nine years in Indian waters from 1746, and then was redeployed to the Jamaica station from 1755–58. The ‘Princess Mary’ was sold in 1766. The ‘Augusta’ (SLR0448) and the ‘Worcester’ (SLR0444) were ships of the same class.
