Using Routing Points

Short Description

Routing points are specific locations that a vessel pass through when en routeTherefore, 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.
