3-10-3 Auto tacking or gybing in wind mode
If the set wind angle (SWA) is 90° or less, the boat tacks, if the SWA is more than 90° the boat gybes. After the
tack or gybe, the SWA is the same as the SWA before the tack or gybe, but from the other side.
• press , select Tack/Gybe then press
to tack or gybe to port
• press , select Tack/Gybe turn then press to tack or gybe to starboard
Example:
SWA is 40°, so the boat will tack, not gybe. If the tack angle is not set to Auto, the boat changes direction twice:
- first by the tack angle
- second so that SWA is the same as before the tack or gybe, but on the other side:
After the boat has reached the tack angle, the boat turns again so that
the SWA (set wind angle) is the same as the SWA before the tack, but
from the other side
Wind
SWA = 40°
Press , select Tack/Gybe
then press initiate a tack
to port.
The tack is finished when the boat reaches the new wind angle
To cancel the tack at any time, press
At the end of the tack delay, the course changes by the tack angle (in
this example, the tack angle is not set to Auto). The boat turns.
The boat sails straight while the NS3300 Pilot counts down the tack delay.
The unit gives a long beep at 60 and 30 seconds to go, a short beep every
second from 10 seconds to 1 second to go and a long beep that finishes
when the countdown ends.
3 seconds to go until the tack starts
