As usual, Jared has hit the nail on the head.

I'd like to add to his comments by saying that in my experience, in small
boats, maintaining a heading to within +/- 5 degrees is about the best that
one can expect. Everything else is just an illusion. Either that or I am a
lousy helmsman!

all practical purposes. No helmsman can work to single degree accuracy
except an autopilot and that's an illusion too...so the absolute accuracy of
the GPS's doesn't really matter, does it? I think they are all sub-degree or
nearest degree, that's a decision to be set by whoever makes the firmware
and hardware.
