• Distance between two points on the route,<br />

• Running time, with polar speed, from the beginning of the trip,<br />

• Speed reference: from the beginning of the trip, with a calculation for wind taken into account (wind at the<br />

beginning of the trip).<br />

• This indicates, depending on the isochron interval selected (6 hours in this case), routing points, hours, vessel<br />

speeds, headings, true and apparent wind at these points.<br />

In each point of the route contains:<br />

• A passage date (column from the table " ETA ")<br />

• A state of the current at this date: direction and speed. These parameters are represented in the table by<br />

columns "Dir. Current" for the direction of the current and by " Current Speed " for the speed of the current.<br />

• A state of the wind at this date: direction and speed. These parameters are represented in the table by columns<br />

" Dir. Wind " for the direction and by "Speed True, Apparent" For the wind speed.<br />

• Apparent wind and close to a point, these parameters are represented in the table by the columns "Ang. App.<br />

Wind" For the apparent angle of the wind, "App. Wind Sp" for the apparent wind speed and " Rel. Wd. Ang. "<br />

for the relative angle of the wind.<br />

The Route List shows the coordinates, together with time, yacht’s speed, heading, actual and apparent<br />

wind for each isochron at the intervals specified (of 6 hours in this case)<br />

Note: as well as giving important help in predicting changes in wind direction and force, the route<br />

list also allows you to pin-point any differences between the forecast weather conditions<br />

(from the weather file) and those actually being experienced. The software offers you tools<br />

to modify the weather file (refer to the next paragraph, Modifying the weather file ) if<br />

necessary to make your navigation more accurate.<br />

Selecting an optimal routing<br />

You may want to select a course other than the optimum route which the program has calculated (in order<br />

to monitor a competitor, or to maintain a position favorable to predicted changes in weather conditions).<br />

Go to the [Performance] menu and choose [Select Alternate Routing] ; the Finger tool will automatically<br />

be activated.<br />

Use the Finger tool to click at the desired point on the isochron (the isochrons need to be displayed on the<br />

chart); after a couple of seconds the following dialog box will be displayed:
