Extract

A variety of marine requirements has prompted the Hydrographer of the Navy to design a plotting diagram printed on a transparency which is now under trial in prototype form. British Admiralty chart 5028, as this project is officially called, comprises a thin sheet of flexible and transparent material slightly frosted on one side to take ordinary black lead pencil work. The plotting area is printed on the frosted side and its circular portion has a diameter of 20 inches.
