Scale 1:96. A comparative plan depicting the hulls of two unnamed 20 gun Sixth Rates; one of 92ft 6in length and the other of 93ft length. For each vessel, the plan shows the after body with sternboard, sheer lines with outboard detail above the waterline, fore body and longitudinal half-breadth.

The Keltridge Draughts all carry a very high level of detail, paticularly in relation to the exterior fittings and decoration of the ships depicted. On this drawing, the vessels are shown with their lower masts in place, each flying a large flag (the usual practice for new vessels when they were launched). The flags depicted include the naval ensign squadron flag [the colour is not specified on the plan], the Royal Standard, the Lord High Admiral's flag, and the 1606 Union flag.
