Introduction
On a SAIL boat under autopilot control, you can use AutoTack to define how the boat tacks.
• When using AutoTack outside of Wind Vane mode (standard AutoTack), the AutoTack
angle is the angle between a port tack and a starboard tack. The default angle is 100°. .
• When using AutoTack in Wind Vane mode, the tack angle relative to the wind on one tack
is mirrored on the other side of the wind on the next tack.
