At sea, the race organization may send files containing the positions of the boats in the race. Two formats are generally used, the Maxsea(or Adrena) format and the Expedition format.
Maxsea and Adrena use the same format. The only difference between Maxsea and Adrena is in the header line. The following lines include a line number, the boat Id in the race, the latitude, the longitude, and the UTC time of the position.
Note that the Maxsea/Adrena file header can also be: POSREPORT
Here again, we will prefer the Maxsea or Adrena format, easier to read with the naked eye.
