LOL! I'll go with True, to match the way my papyrus charts are printed...
I'm still trying to wrap my mind around how someone on a passage from Newport to Bermuda, for example, manages to plot their position (or that of the Gulf Stream, for that matter) every few hours, or with each change of the watch, on an upside-down copy of Chart 13003... (grin)
Good points you make about our various individual means of spatial orientation, we're all 'wired' somewhat differently, no question... Still, I tend to generally associate Heads-up with Powerboating
, and North-Up with Sailing...
The reason, of course, is the vital importance to most sailors of Wind Direction
in planning, and navigation... Again, perhaps it's just me, but it is SO much easier to visualize wind direction relative to the course to be sailed on a simple North-up display, than it is to go through the mental gymnastics required to calculate or estimate wind direction on what might be a constantly shifting heads-up orientation...
Yet, the ever-increasing popularity of this sort of Plug-n-Play Piloting - waypoint to waypoint, routes created and interfaced with an autopilot keeping you on the straight and narrow 'Highway' - seems to me but one more contributing factor to many of us Motoring More, and Sailing Less... (grin)
