"Given the pleasure presumably associated with moderate drinking, claiming there is no 'safe' level does not seem an argument for abstention," he said.
"There is no safe level of driving, but the government does not recommend that people avoid driving.

Now I must disclaim that obviously the crew wasn't forced to drink. Those on guard, or who had any medical, religious or other objections were dismissed. And naturally they have very strict limits, as getting intoxicated on board of a operational warship would be very dangerous.
But, with moderate use, alcohol was (at least back then) viewed as an efficient method to prevent stress and mutiny among the crew. It probably is still today.
