You got 'twin hulls' disease....
I won't argue with you about the merits of at least understanding the benefits of doing routine compass checkery. I reckon that kind of thing was done quite frequently in Her Maj's Subsurface Service, too, whenever the opportunity presented..... despite the wonders of strapdown laser ring gyros ( several of ).
Doing frequent compass checks was mandatory and frequent - like every 15 minutes - in HM's Airy-Fairy Service, too, for at ground-speeds of over 600 knots one could get a very long way off course in a short time, if something disagreed with the heading reference sensors. A perhaps apocryphal story is told of an RAF VC10 ( 'Shiny Fleet' ) heading from Brize Norton towards Washington ( embassy run ) one fine day when, after some hours, the lead hostie popped onto the flight deck with some coffees and biscs. 'Ooo!' she remarked, peering out the windows, "The sun's right in front of us. I'd imagined it would be out to our left....."
There was a strained silence, while every head turned towards the 'First-Tour' navigator, deep in his copy of 'HitchHikers Guide To The Galaxy'. I believe they made an unscheduled landing at Jamaica..... and the navigator made his own way home as a plain 'mister'.
