I have to hunt further to find the frequencies I have. But I found them by
accident. The FCC surely has a detailed list of frequency allocations.
Examining such a map may reveal what frequencies they would likely use if
they do not use regular amateur equipment.

There are a lot of frequencies in use by commercial vessels and

Thanks for the list, but what I had in mind are the non-official simplex
freqs which real fisherman use to chat and swap notes while at sea, and
not
to communicate with shore stations or the coast guard. I used to hear
many
such boats years ago, similar to the 2958 I mentioned.

Similarly, many foreign ship-board radio operators chat off-channel on
non-
official freqs scattered in the marine and aero SSB bands.
