Have been trying to sort out my Raymarine
Pilot and have hit the limits of what to try.
Basically, on some courses I get decent performance (in calm water
, haven't tested in rougher conditions), but on other courses this thing wanders like a very drunken sailor... swerving 30-40+ degrees each way.
I have done the resistance tests on the fluxgate compass
and it tests out OK. I tried to calibrate (motoring in circles) with compass
where it was mounted by PO (who swore it worked well, at least according to broker) and couldn't get better than 40 degrees deviation, so moved the compass to another (temporary) location and got the average deviation down to 8 degrees, but I still get really bad performance on some/most headings.
Any ideas what to do next? Do I just buy a new compass and hope it was that? I have tried some settings (I'm up in Pacific Northwest
so set auto adapt to north and set latitude to 48 deg, which seemed to help a bit) and have played with the rudder
gain to no real effect.
For clarification, this is wheel
pilot on Gulf 32 Pilothouse, no rudder
sensor, just trying to run on compass course (no GPS
direction or anything).
Any tips much appreciated.
