1719 Establishment Group

The 1719 Establishment Group of sixth rates defined the 20-gun sixth rate using the Dursley Galley as a model. This design works and sailed well. Seventeen ships would be rebuilds of earlier vessels, some would be fifth rates, a couple of fireships and three vessels of new construction with the majority rebuilt from older sixth rate vessels. These ships would be constructed between 1722 and 1727.

Design and specifications
The construction of the vessels was assigned to Royal dockyards. As with most vessels of this time period only order and launch dates are available. The dimensional data listed here is the specification data and the acceptable design creep will be listed on each individual vessel. The gundeck was 106 ft with a keel length of 87 ft for tonnage calculation. The breadth would be 28 ft with a depth of hold of 9 ft. The tonnage calculation would be 375 tons.

The gun armament as established in 1703 would be twenty 6-pounder 19 hundredweight (cwt) guns mounted on wooden trucks on the upper deck (UD).
