True Wind Mode
This mode requires a speed sensor, a compass sensor, a wind sensor and the
software add-on « true wind ». Once this mode has been selected the pilot steers the
boat to a set true wind angle as calculated by the processor.
The true wind mode is particularly well adapted to downwind conditions in waves.
These are the conditions where the nke pilot demonstrates its true capability. If
apparent wind was used you would get the following issues:
- The boat sails down the wave and apparent wind speed increases, the apparent
wind angle decreases: it is a header, the pilot bears away to maintain the wind
angle it is set to steer to.
- The boat sails up the wave and apparent wind speed decreases, the apparent
wind angle increases: it is a lift, the pilot luffs up to maintain the wind angle it is
set to steer to.
As a result, in waves the apparent wind mode is not efficient and it is better to select
the compass mode to keep a straight course.
With true wind mode the pilot steers the boat on a straight course keeping the
optimum wind angle in the waves. The wind angle to steer is not affected by boat
speed variations. While sailing solo it is very efficient to leave the pilot to steer the
boat and focus on sails trim (just watch power consumption).
True Wind software add-on
A code is required to activate the true wind mode function. Please contact your nke
dealer to get this code. The code number is linked to each Gyropilot 2 processor,
your dealer will need your processor’s serial number to issue the code for the
software add-on. This serial number can be found on a label on the processor itself
or in the true wind menu of the Multidisplay.
Activation of the true wind add-on:
The hexadecimal code is entered with the virtual keyboard. Once the function is
activated the little padlock symbol will turn open and green.
Apparent Wind mode
This mode requires a speed sensor, a compass sensor and a wind sensor.
With the apparent wind mode the pilot uses data from the mast head unit through the
Topline bus to steer the boat on a set apparent wind angle. This mode is mainly
used while sailing upwind.
