As I recall, the Nimrod MR1 suffered only one serious quirk when crossing the equator southbound. The navigation systems performed flawlessly and "George" flew her smoothly, thus allowing King Neptune to convene his court, with proper ceremony, in the galley, where the yoofs on the crew would pay homage. Suitable tribute, in the form of a tincture or twain for the old hands, would be paid after landing.
Cheers,
Neppy
