D.
Start line
The committee boat is symbolized by the buoy on the right and the pin is the buoy on
the left.
The favourable side is green. In this example, it is the committee boat.
16° shows the favourable angle value. In this example the wind angle to the right side
of the perpendicular to the line is 16°.
By knowing the start line length, the MultiGraphic can calculate the gain to windward
difference between both ends of the line.
In this example, the 16° favourable side on the committee side of the line gives a
228 meters gain to windward for a 796 meters start line. This interesting information
shows that the gain to windward grows considerably with the line length and
favourable angle value.
E.
Distance to the line
The distance to the line is displayed in meters and boat lengths.
The value displayed is the distance between the line and the boats bow (not the GPS
antenna's location). The boat's size and the distance between the GPS antenna and
the bow must be entered in the system via the menu Performance
parameters.
F.
Start line's length
This is the distance between the committee and the pin in meters.
G.
Time to the line
The remaining time to the line is calculated from the speed over ground, so that the
effect of the current is taken in account.
The time is displayed in seconds when it can be calculated. It is the time required for
the boat to reach the line, given the current boat speed and heading.
Should boat speed or heading change, the time to the line is updated.
H.
Start line orientation
This is the bearing of the pin from the committee boat side given in True degrees.
The variation must be added to get the Magnetic bearing.
