I'd point out that some GPS units, especially the multifunction display type units, may be showing a magnetic heading based on a FLUXGATE compass, rather than on GPS-calculated movement over ground, as Jerry describes.

It would help if the OP said exactly what electronics he has aboard. The C60 is a relatively vague description, since the C60 can have both a fluxgate compass and a GPS antenna attached to it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
