STYX, the Movie

Quite a good sailing movie about a German physician who sets out on her sloop, the Asa Grey, probably a Beneteau (which she tells the Coast Guard is ten metres), from Gibraltar for Assension, a suburb of St. Helena in the Eastern Atlantic.
The sailing is more realistic, than in Robert Redford's All Is Lost. Well not perfect: she failed to scribe a line on her chart along which to mark off the mileage with her dividers. But the storm, the calm, the very limited dialogue. She has an EPIRB and both VHF and SSB and uses them all well.
This is also a film of ideas and ethics, but without preaching. The title comes from classical mythology:  the River Styx is the water passage between this world and the underworld, which her voyage turns into, becoming a suspense thriller.
Her objective, as shown by her leafing through picture table books of flora, was to study the lush tropical botany at her destination, a place associated with Charles Darwin. And her boat's name is a homonym for Asa Gray, the most famous American botanist of the 19th Century and a frequent correspondent with Darwin. The internet led me to that nugget while I was trying to get it to tell me what make the boat was.
The ethical and moral choices come later and I won't spoil the movie for you by describing them.
The film has been rather favorably reviewed by the professional reviewers and is continuing at the Film Forum on Houston St., half a block west of Sixth Avenue, in Manhattan, but only until March 12. After that it may appear in art film houses and streaming.
Sailors will both enjoy and be moved by this movie.
