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 the crossed areas. 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.

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 (in m), length (in m), maximum draft (in m)). 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 (in m) 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, length) 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)).

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).

Departure time (Unix time in ms) and speed can be specified in order to get an accurate ETA. The speed can be given in knots using the parameter speedInKts or in km/h using the parameter speed. The ETA (Unix time in ms) and duration (in ms) take into account the maximum authorized speed in specific areas such as canals. If the vessel speed is superior to the authorized speed of a crossed area, we assume the vessel will sail at maximum authorized speed in the area and at the given vessel speed outside the area.

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, the 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.
