I would suspect the fluxgate compass may be located in a bad place on the boat where it is affected by something metallic. Or maybe the wiring is experiencing a surge from a power source? Besides many hours of sailing and motoring a narrow ICW channel, I made at least seven 12 to 13 hour trips using our ST 4000plus and never experienced that problem. Six hours from Atlantic City to Cape May and six hours Cape May to Greenwich, NJ.

We motor to Solomons and back, 13 hours each way. It usually does a pretty good job, but once in a while makes a 90 turn and tries to run us aground. I like it, but I also need to keep an eye on it.
