Nautical globe. This globe was designed for navigation teaching purposes, and was used along with a chart also designed by Hatch and in the National Maritime Museum, London collection numbered G215:1/26. The globe is potentially connected with the requirements of certification under the 1850 Mercantile Marine Act.
The globe and the chart, with their ivory fittings and ships, are unique items in the history of globe making. No other globes have been recorded which were designed for the sole purpose of teaching the navigational problems of plane sailing.
