RTE – Routes
Waypoint identifiers, listed in order with starting waypoint first, for the identified route. Two
modes of transmission are provided: "c" indicates that the complete list of waypoints in the
route is being transmitted; "w" indicates a working route where the first listed waypoint is
always the last waypoint that had been reached (FROM), while the second listed waypoint is
always the waypoint that the vessel is currently heading for (TO) and the remaining list of
waypoints represents the remainder of the route.

Waypoint "n" identifier (see Note 1)
Additional waypoint identifiers (see Note 1)
Waypoint identifier
Route identifier
Message mode: c = complete route, all waypoints
w = working route, first listed waypoint is "FROM",
second is "TO" and remaining are rest of route
Sentence number (see Note 2)
Total number of sentences being transmitted (see Note 2)
NOTE 1
A variable number of waypoint identifiers, up to "n", may be included within
the limits of allowed sentence length. As there is no specified number of
waypoints, null fields are not required for waypoint identifier fields.
NOTE 2
A single route may require the transmission of multiple sentences, all
containing identical field formats when sending a complex message. The
first field specifies the number of sentences, minimum value = 1. The second
field identifies the order of this sentence (sentence number), minimum value
= 1. For efficiency, it is permitted that null fields be used in the additional
sentences when the data is unchanged from the first sentence.
(Note that this practice can lead to the incorrect assembly of sentences if
there is a high risk of loss of sentence.).
