All these ex-submariners - like Darryl Manzer here - dispensing advice about how they lived with "social distancing."
Fact is they were the least socially distanced of any profession.
60 to 150 submariners (who volunteered) to be crammed into a narrow metal tube - slept, worked, ate, watched movies, next to each other, chatting (or formal voice interacting) face-to-face about 18 hours a day. Also physically dodging/squeezing around each other in the narrow spaces for months.
Submariner "Social Distancing" bears little resemblance to enforced COVID-19 social distancing. With COVID meaning being involuntarily stuck in your home/flat alone (or with only 1 or 2 others) sharply curtailing the face-to-face interaction you're used to.
Spacially - Submariners being crammed with others night and day is totally unlike COVID 1.5 meter separation social distancing (a COVID "treat" being off to the supermarket for a half hour 2 times a week).
Submariners had/have it tough but COVIDteering (though less so) also has its pressures - in very different ways.
Bunks in 1940s-60s Gato-Balao-Tench (still, 2 Hai Shih) class submarines. Similar lack of social distancing in Oberon class bunks and those in later SSKs.
