As usual Google is your friend:

here's one from an official source:

Is there a (number) of channels where it is acceptable to simply carry on a
casual "chat" with other boats?


Most people use channels 68, 69, 71 and 72 for casual communication.
It is not a good idea to carry on a prolonged "chat" however since
these channels are heavily used in many areas. You should always use
the low power setting when at all possible to minimize interference to
others and the number of people listening in.
