Scale: 1:48. A contemporary full hull model of a 74-gun two-decker ship of the line (circa 1760), built with a 'bread and butter' core, planked and finished in the Georgian style. Model is partially decked, fully equipped, rigged and mounted on its original baseboard. At this scale the model depicts a ship with a gun deck length of 166 feet by 47 feet in the beam and a tonnage of 1600 burden. A noticeable feature is the raised position of the channels that support the shrouds above the upper gun deck. The rigging is modern and was fitted in 1976.

There is a possibility that the model may depict 'Thunderer', or a similar ship, 'Hercules'. During the 18th century, attempts were made to find the optimum size for a ship of the time to carry the maximum armament on two decks. By 1757, the 74-gun ship of about 1600 tons burden was evolved and this, with minor modifications, was to become the standard medium sized fighting ship for the next 50 years.
