Evolution AP not steering to waypoints without getting lost

The default would be the Speed, so make sure it is set to SOG, and it could be effected that far down the line because of the change in course by current, side wind, side waves and this is when the autopilot is trying to correct causing the S-ing.

How was the C80 connected? Through a Seatalk to Seatalk NG converter or through a NMEA converter? The C80 would not have a direct connect to a Evolution autopilot it doesn't have Seatalk 1 or NMEA 0183 inputs?

We were facing a fairly strong sidewind now that you mention it, and the waypoint in question is off the end of an island so could easily have strong winds around it the other times he had this happen when I was not on board. I'll make a trek down to his boat soon to verify these settings. Do you know where in the menu I should look to make sure i'm checking the right setting?

As for the C80, it was ST1 out and into a Raymarine ST to STNG converter (yellow plug) into the EV.
