Hi folks,
I was out on the boat today trying to get some solo time in. The good news is that she sails great, 20 knot winds, full sails and all.
The this was though that throughout the Spring I had noticed the autopilot as being off by some 30-35 degrees. Not having had an autopilot in the past I just left that to the last to experiment with so...
Today I'm sailing out of Salem harbor with the motor idling just in case. The auto pilot is off by 30-35. About half way out of the harbor I shut down the engine and a little later I notice the auto pilot is pretty much within a few degrees of the compass. I think, well maybe it just had to warm up.
Sailing with the auto pilot worked well. When engaged it kept the course. It even tacked properly, until it came on course at which time it had trouble holding. But I chalked that up to the 20nm winds and the fact that I had all the rags fully out.
Comming back in I decided to hall down the sails and motor. Low and behold the auto pilot went off by the 30-35 degrees. And, something I had slightly noticed before, the integrated chartplotter display is also off from th e"heads up" orientation - by 30-35 degrees. I turned the auto pilot off and instantly the chatplotter displayed correctly.
Checked the fluxgate compass and there was nothing near it.
About three weeks ago I was out following the manual and doing the calibration thing on the autopilot buy got a message back that the deviation was 26 degrees.
Anyone had a problem like this?
