What is a routing chart?

Answer 3

Admiralty Routing ChartsThese are published for all major oceans for each month of the year.

The charts display ‘average’ conditions for the time of year. Wind is presented in the form of ‘wind roses’ which give a graphical representation of the strength and frequency, currents, sea temperature thermobars, fog and ice frequency along with the tracks of tropical revolving storms all assist in passage planning.
