Par défaut, le WP est celui de la prochaine marque. Dans notre exemple, comme la course n'a pas encore débuté et que les bateaux sont encore sur la ligne de départ, le WP est 51°23'03"N 009°36'00"W situé à 319.26 nm au cap orthodromique 282.1 comme c'est indiqué sur ce cadran.
+
In our example, as the race has not started yet and the boats are still on the starting line, the WP is 51 ° 23'03 "N 009 ° 36'00" W 319.26 nm located at 282.1 great circle as indicated on the dial.

Pour obtenir comme WP les coordonnées de la prochaine marque, il faut que la valeur 0 soit inscrite dans les cases Lat et Long comme sur l'image ci-dessous
+
To program the next WP to be the same as the coordinates of the next mark, you must enter the value 0 into the boxes Lat and Long as in the picture below.

Mais si l'on programme le pilote orthodromique (ou meilleur VMG) directement sur ce point, c'est l'échouage garanti comme on le voit fort bien sur l'image du parcours
+
But with the next WP as the next mark, if you program the pilot for better VMG, you will become Grounded for sure, with a penalty guaranteed, as seen easily from the inboard course image below.

Aussi nous allons choisir un WP approprié pour contourner la pointe Lizard (approximativement à 49°57'N 005°12'W). Avec un peu de prudence, pour ne pas se cogner dans Start Point, la pointe au sud de Plymouth, retenons 49°48'N 005°12'W. La saisie ce fait en degré décimal, soit 49.8 et -5.2. Pour mémoire, il faut diviser par 6(=1') le nombre de minutes, idem pour les secondes.

Alternatively and more safely we should choose a suitable WP to circumvent the tip of Lizard (approximately 49 ° 57'N 005 ° 12'W). With a little caution, so as not to bump into the Point, the southernmost tip of Plymouth, retain 49 ° 48'N 005 ° 12'W. This entry is in decimal degrees, or 49.8 and -5.2. For the record, we must divide by 6 (= 1 ') the number of minutes, same for seconds.

Ainsi nous pourrons utiliser le pilote orthodromique et meilleur VMG sans risquer de s'échouer (si les vents ne changent pas complètement et nous envoient tout de même sur la côte, mais ceci relève du routage et plus du mode d'emploi des instruments).
+
So we can use the driver circle and better VMG to fail safe (if the winds do not change completely and send us all on the coast anyway (however is nature of the routing and mode of use of instruments).

Important : Le système considère un WP comme atteint lorsque la distance entre le bateau et ce WP est inférieur à 1/12 de la vitesse du bateau à la dernière vacation, soit approximativement la distance parcourue lors de la dernière vacation (par exemple, à une vitesse de 24 noeuds, le bateau "atteindra" le waypoint lorsqu'il se situera à l'intérieur d'un cercle se situant à un rayon de 2 milles du WP). Ces dernières informations sont valables pour les courses avec des "vac" toutes les 5 minutes (pour les courses avec d'autres "vac" il faut adapter selon le cas)
+
Important: The system considers a WP be reached when the distance between the boat and the WP is less than 1/12 the speed of the boat at the last session, approximately the distance traveled during the last session (eg, with a speed of 24 knots, the boat will reach the WP when the waypoint will be located within a circle with a radius of 2 miles ranging from the WP). Recent information is valid for racing with "vac" every 5 minutes (for races other "vac" should be adapted as appropriate)

This option gives you the ability to have your own way point.

If no value has been filled, your Way point (WP) is the next mark, provided (lat,lon) are entered as '0'. When you fill a value (lat, lon) in the 2 WP text boxes, the next race mark is forgotten until you reach your waypoint.

As a race mark, WP can be used with the following modes : Orthodromics pilot, best VMG and VBMG (Constant heading and Constant Wind Angle don't use the WP).

Race mark coordinates can be found into Course instruction or on top right of the UI when mouse navigates over mark number (see screenshot).
