WIND 3100 Installation and Operation Manual
5 Steer to wind
The required steering angle is 40° and the boat is at
30° to the apparent wind. The steering error is 10°.
The boat should turn 10° to port. The steering
resolution is 1° and so 10 segments of the circular
display are on:
The steer to wind function gives steering instructions
to sail at a constant angle to the apparent wind. The
WIND 3100 automatically calculates the correct
instructions for port or starboard tacks.
To start steering to wind, press
until STEER is
displayed. The display shows:
1
The required steering angle to the apparent
wind (to set the required steering angle, see
section 5-1).
2
A direction arrow showing which way to steer
to reach the required steering angle.

The steering error (the difference between the
required steering angle and the actual steering
angle) is shown on the circular display:

The required steering angle is 40° and the boat is at
70° to the apparent wind. The steering error is 30°.
The boat should turn 30° to starboard. The steering
resolution is 5° and so 6 segments of the circular
display are on:
The top two segments are always on
The greater the steering error, the more
segments turn on
The steering resolution determines how
many segments turn on. The number of
segments that turn on is the steering error
divided by the steering resolution (to set
the steering resolution, see section 5-2).
If the boat should steer to port, then
segments to the right of centre turn on
If the boat should steer to starboard, then
segments to the left of centre turn on.
