Charts and Courses of a Ship

The selection of the route depends on the depth of the water, the shortest track, scenery, weather, currents, as well as many other factors. When the course lines have been drawn, distance and speed have been calculated, it is time to call the Captain to approve the intended route. Under his guidance adjustments are made, the approaches to each port finalized, anchorages selected, and alternative scenarios developed in case they are needed.
