Anyone else like me remember getting there Marine Endorsement on their commercial license? Would assume it’s completely useless today but in 1977 had to memorize 2182 as the international distress frequency and that you had to monitor it at least once an hour while under way. That along with other useless information like the fully charged gravity of a wet cell and how to clean a dynamotor.

I also got the broadcast endorsement and got a lot more use out of that, was never smart enough for the radar endorsement.
