Scale 1:32. This contents of this sheet are in two distinct parts. To the left is a plan showing the midships section of an unnamed two-decker. The purpose of this drawing appears to be instructional, as the component beams and frames are all named. Accompanying text discusses the calculation of weight and displacement in relation to hull size, shape and capacity. Guns with individual members of their crews are also drawn in, presumeably to scale. The types illustrated are 6 pdrs on the upper deck and 12 pdrs on the gun deck.

To the right of this plan is a table of weights showing a breakdown of the total tonnages of equipment and stores required by ships of various Rates. Although no direct reference is made, it is very likely that the ships used as examples in this table are the same ships represented in the other Keltridge drawings.

The Keltridge Draughts all carry a very high level of detail, paticularly in relation to the exterior fittings and decoration of the ships depicted.
