Menu |
This menu is available on the left after selecting the button ![]() List of routesThis button displays the list of available routes. Click on the name of a route to display its contents in the menu below.- The loading button on the left allows you to reload the previously saved route file. - The button on the right allows you to save all of the modifications made. This save is automatically carried out when the software application is closed. The name of the routeThe name of this route is displayed in the following box.

When blue the route is displayed on the map, when orange it remains invisible. - ![]() Show date and time for each position. Fixed speed freeze the speed or the date for each position. Constant speed allows you to set a constant speed based on the current position and for the rest of the trip. Copy the route : the current route is duplicated. Start by changing its name, then personalize this new route. This is also the way to create a new route : once you have created it, delete all the other positions (except for the 1st that cannot be deleted), then define your new trip. Delete the route : the current route is deleted. Note that this deletion is not possible if the route is the only remaining one. - ![]() - ![]() - ![]() - ![]() - ![]() The positionsEach box defines a precise position on the route and contains :![]() - On the 1st line a button allowing you to activate the current position (making it modifiable on the map with the mouse), the date year, month, day and time (UTC) in hours and minutes, and a button that displays this help. - On the 2nd line the position, the latitude and the longitude in degrees, minutes and seconds and the speed of the boat in knots between this point and the following one. - On the 3rd line the course of the boat in degrees between this point and the next point, the distance traveled between the point of departure in nautical miles, the remaining distance to cover until the last point, a "+" button allowing the insertion of a position after the current position, on the map the "Insert" button has the same function, and a "-" button to delete the current position; on the map the button "Delete" has the same function. - The distances are calculated on the loxodromic route (route with a constant course). |
To Copy or Create a route |
- In the Tools menu select Copy the route. A new entry is created and displayed in the menu List of routes. You can now rename this route, correct the positions or delete them all, except for the 1st, to then create a new one. Note that a route can only have one position. On the map, the right button of the map allows you to create your route by adding new positions at the end. |
To Delete a route |
- In the menu Tools select Delete the route. The current route is deleted, and the previous route in the menu List of routes is then displayed. You cannot delete the only remaining route. |
To Modify a route |
You can modify the elements describing the route, date, position or speed at any time, in the routes menu on the left.
In the menuThe date, position and speed are modifiable, with the wheel mouse, or by pressing down on button 1 of the mouse and sliding it, or by directly typing in the desired value.On the mapTo modify only the position, on the map where the plotting of the route is visible, you must switch to editing mode, either by clicking on this button in the menu (it should be blue) or by typing on the E key. Press a second time to quit this mode. The figurine representing the position is then displayed in black. You can modify its position by clicking on the desired spot on the map.To move to the next position, click in the menu on the left on the button corresponding to the position (this button should be blue) or press the Z key to activate the previous position, or the R key to activate the next position. To Insert or Delete a position- To insert a new position after the active position, click in the menu on the left on the "+" button of the position after which you want to add this new position, or more simply, press on the "Insert" button on the map. - To delete the active position, click in the menu on the left on the "-" key of the position that you want to delete, or more simply, press on the "Delete" button on the map after having selected the active position. NoteThese keyboard keys remain accessible even if the Routes menu is not displayed, which makes it possible to modify your route according to the forecast weather conditions. |
Notes |
-When you create a route made up of points in chronological order, the displacement speed is arbitrarily set at 10 knots.Constant speed (Tools menu)- Once the route has been plotted you can change the speed along the whole itinerary by activating the 1st point, giving it the desired speed and clicking on "Constant speed" in the "Tools" menu.Fixed speed (Tools menu, checked)Checked by default. The speed between each segment is preserved if we modify or correct position. The dates of the current point and all the following items are changed.Fixed speed (Tools menu, unchecked)- If you change the position of a point, the speed of previous and following segments are changed but all the dates remain unchanged- If you modify the speed on one point of the trip, this modifies all the dates of the following positions. -The maximum speed is set at 100 knots. If you cannot move a point or correct a date, it is probably because the speed induced by this modification exceeds this limit. - Note : to cancel the display of the help balloons, type"T" on any button or field, and type on this key again to re-display the help balloons. |
Display of the current position |
The current position of the defined and visible route(s) is (are) displayed in the form of (a) white figurine(s). This position is estimated according to the course and the speed. It is updated again every minute. This figurine is not displayed if the current date is outside of the time limits for the route. To insert the current position in your trip, switch to editing mode and press on the D key. Then all you have to do is correct this active position with the mouse or in the new position box displayed in the left-hand menu so that your exact position is calculated or indicated by your GPS. |
Displaying with the weather |
When a Grib file is opened and displayed, a red figurine appears and symbolizes the position of the boat at the displayed range (estimated position taking into account the course and speed you have chosen) on the route(s) displayed. This figurine does not appear if the range is outside of the time limits for the route. This position moves when you change ranges to reflect your future position at this range. It is thus possible to view the weather conditions for your route ahead of time and possibly modify this route to avoid extreme conditions. |
Histogram |
If a Grib file is opened, it's possible for each route, to display a histogram, giving you instantly, the weather forecast
at each step, at the corresponding position, on the route. The route must be Visible.
Use the "Routes" menu button ![]() This histogram does not appear if Grib forecasts are outside the temporal limits of the route. You can display one histogram by route. The histogram is automatically recomputed if you change one element of the route : time, speed or position of an inflection point. Closing Grib file or opening another file does not clear or does not update the histogram already displayed. We must close the histogram window and open it again to display the histogram of the new file (Click 2 times on the ![]() NOTES : You can move the window containing the histogram and also resize the width to improve readability. |
Example on a route from Brest to Istanbul from April 25 at 18h to May 4 at 06h (speed 15 Knots).
The colors used are those set by default to display the wind and the sea (Beaufort scale and sea state scale).
Rate a singularity : an east wind force 7 (orange) which coincides with the passage of the Gibraltar Strait (Strengthening local winds associated with particular relief of this place). ![]() |
