Scale 1:192. Plan shows the sketch of sails, as proposed for the Monarch class masted turret ship Monarch (1868). The title of the drawing is "Sketch of sails as proposed in black and as present in red". The proposed sketch of sails is drawn in black ink while the present drawing of sails has been drawn in red ink. The drawing also shows the details of sail measurements both proposed and present. The plan is fragile and torn.
