Can I do a large dile in then swing the the boat for deveation?>
Have you tried to follow the procedure for swinging the fluxgate?
A difference of 131 degrees is much...
What is the correct heading when you are tied up at the dock?
If it is the fluxgate that is off, you must check for any magnetic sources close to the heading sensor, lumps of iron (engine, fire extinguisher ++) , electrical components.
Worst case the heading sensor must be re-positioned.
It cold also be the magnetic compass that are off..
