Nodrift Mode - Simrad IS40 Operator's Manual

To tack or gybe in wind mode press both 1° course keys on the OP10 Autopilot controller
together.
When you enter a command to tack or gybe a pop-up will appear on the display asking you
to confirm the action.
Pressing 'Enter' on the display, or 'Auto' on the autopilot controller, will activate the tack/gybe
function and the boat will start turning to the new wind angle.
¼ Note:
To cancel the tack/gybe request, press the 'STBY' key on the autopilot controller or
select cancel using the display. If neither Tack/Gybe or Cancel is selected the tack/gybe pop-
up will close after 10 seconds and the requested tack/gybe will not be initiated.
¼ Note:
The autopilot will temporarily add a 5 degree bear-away on the new tack to allow the
boat to pick up speed. After a short period the wind angle will return to the set angle.

NoDrift mode

¼ Note:
NoDrift mode is not available if the system has been set up for Sail in
the Installation Menu.
In NoDrift mode the vessel is steered along a calculated track from present
position to infinity in a direction set by the user. If the vessel is drifting away
from the original course line due to current and/or wind, the vessel will
follow the line with a crab angle.
Press the 'Mode' key until the NoDrift mode symbol is visible in the mode field on the display.
The autopilot will now use the position information to calculate the cross track distance, and
automatically steer along the calculated track.
¼ Note:
It is not possible to select NoDrift if position or heading
information is missing.
The autopilot will keep the boat on that course until a new mode
is selected.
Prior to entering NoDrift mode the autopilot system should be
operating in Auto, with valid input from the GPS receiver.
