As a passenger on the Queen Elizabeth 2 on a westward crossing of the Atlantic in late May 1972, I took sextant sights with my standard marine Plath sextant and also with the ‘bubble’ attachment for this instrument. Inspired by Francis Rogers' discussion of the development of bubble sextants, my project was to compare the accuracy of the bubble sights with that of the conventional marine sextant sights, which require the horizon.
