Routing points are specific locations that a vessel pass through when en route. Therefore, the number of routing points and a high level of detail is vital to the accuracy of a calculation. By default, the DDT schedules the shortest viable route. To change a route, routing points can be inserted and the sailing route will re-route via the inserted routing point, for example, instead of sailing through the Suez Canal, the route is changed to sail around Cape Good Hope/Cape Agulhas.
Each routing point is defined by a unique code and name. Only the routing point code can be used when entering a routing point into a calculation.

Note: If applicable drag the newly added routing point to the correct place in the list of routing points/ports.
