This endpoints returns the route between a source location and a target location on sea, along with the route distance (in meters), duration (in milliseconds) and details about the zones it goes through. We return the shortest route sailed considering traffic separation schemes and port entries.

Coordinate pairs are specified as longitude,latitude, and listed with separating ;. You can specify intermediary points on a route, or request several legs of a trip in one go, by listing more than two coordinate pairs. For instance: -1.26617431640625,50.79551936692376;8.8330078125,53.88491634606499;-3.2409667968749996,53.50111704294316.

Depending on the boolean parameter continuousCoordinates, the longitudes of the points of the route returned can be between -180° and 180° (false) or continuous (ie greater than 180° or lower than -180° after crossing the antimeridian).
For now, the default behavior is to return continuous coordinates (the parameter is set to true as default). However, we encourage the use of normalized longitudes between -180° and 180° setting the parameter to true when requesting a route.

Note that all rivers are available on this endpoint using appropriate vessel draft (in m).

This endpoint additionally returns a list of waypoints of interest in the waypoints fields of the properties of each leg. The waypoints can be of different types :

  • VOYAGE for voyage scale events such as departure and arrival with class either ENTRY or EXIT;
  • ROUTING for special zones with class either ENTRY or EXIT;
  • SECA for ECA zones with class either ENTRY or EXIT;
  • SPEED for points where speed must be adjusted with class INCREASE, DECREASE or TARGET (only used to know the speed at departure when it must be different than the given speed).

You can get vessel specific routes by specifying the IMO number of a vessel. The returned route will be compatible with the vessel dimensions (width, length, maximum draft). If the IMO is not given, We choose a small vessel in order not to block any route.
You can also specify the current draft of the vessel using the parameter vesselDraft, with or without giving an IMO. If both IMO and vessel draft are given, the given draft (in m) is used and the other dimensions (width (in m), length (in m)) are retrieved from the IMO number.
The response contains static information about the vessel used (width (in m), length (in m), maximum draft (in m)).

Departure time and speed can be specified in order to get an accurate ETA (Unix time in ms). The speed can be given in knots using the parameter speedInKts or in km/h using the parameter speed. If the route goes through limited speed areas, these areas will appear as legs in the response.

ECA zones can be avoided by using the parameter avoidSeca.

The HRA (high risk area) zone can be avoided using parameter avoidHRA. If no points from the query are in the HRA zones, the zone will be totally avoided, if at least one point is in the HRA zone, the route will go through it but minimize the distance navigated in it. The distance in HRA is available in the response in the field hraIntersection.

By default, seas that are difficult to sail due to the presence of ice are not allowed (for example the Bering Sea, the Northern Sea Route, etc). You can allow the route to go through these zones by using the allowIceAreas parameter.
