    The Rude Star Finder comes up ever so often and is regularly bashed by the uninitiated. It perhaps has seen its day but it was a most useful tool in the early 1940s when it was at its height of populaity, especially, as you indicate, on a cold wintry evening or morning in a heavy sea with a fleeting cloud cover allowing only an occasional glimpse of a star or perhaps even a planet. Admittedly, however, it has seen its day as has much of traditional navigation although may still be occasionally of use in the event of a  star not covered in one of the moderns pubs being observed..

    No matter how familar a seagoing navigator is with the night sky, this isn't much help at evening twilight when trying to identify individual stars through broken cloud cover, with the traditional pointers from the alignment of neighbouring stars totally invisible.

    The situation in an aircaft, not relying on a sea horizon and and perhaps flying above the weather, is somewhat different. 

    Setting up 2102-D is simplicity itself and yields the useful sextant pre-sets with a minimum of trouble and little stress on short term memory.  Under clear skies at night the selection of a star or planet for a compass error observation is much simpler; then the experienced stargazing navigator will probably leave all aids to star ID on the chartroom bookshelf.

    In the analog age the Rude star finder certainly earned its place in the navigators' armoury.
