When towing the net
When a boat is in tow of the fishing gear, its stern is “dragged” by the net. This causes the
boat to stray from its intended course. To keep the boat on course, you need to adjust the
trim manually, which can be bothersome. If you do not want to be bothered with trim
adjustments, you can enable the automatic towing function to have the trim automatically
adjusted. This feature is very valuable for trawlers and purse seiners.
1. Rotate the course control knob to select “AUTO NET TOWING” from the PARAMETER
SETUP menu.
2. Press the course control knob to show the net towing options window.

Note that you must keep the boat on a straight course before the AUTO mode is selected.
