Starting off from one of the West African ports, as opposed to the Cape Verdes, has the obvious advantage of a better angle in relation to the prevailing winds, so unless one has a very good reason to stop in the Cape Verdes, the valuable easting should not be lost.

It can be assumed that the trade winds will be lost around 25 8N from where it should be easier to make the necessary northing. North of latitude 30°N the winds and weather are very much dependent on the position of the Azores high. If this lies further south than its usual seasonal position, light
