that one is the classic civilian distress freq for aviation. Trouble is, exceedingly few non-airline planes are monitoring that freq. And, I'm not even sure airlines do great job monitoring that. I never did on all my overwater flights. Far more used are the FSS freqs and the unicom freqs for uncontrolled airports such as 122.7 and .8. In "busy" island space, you are on some approach freq; in the middle of nowhere in uncontrolled space, you are busy listening to lots of planes for a dozen miles around at multiple airports. Best to have a green book with the listings of the freqs being possibly used along with that airband radio.
I have an Icom A110 that I have considered putting in my next boat. But not really for emergencies.
We always monitor 121.5 and 123.45 over the ocean. It's come in handy several times, and it's no big deal when there isn't any VHF to monitor and almost no radio traffic anyway.
Just last Atlantic crossing we were able to reach a small jet who ATC has lost contact with, who was at about our position but 4k ft higher on 121.5 and relay position reports, ect to gander on the HF for him.
