Yeah, it wouldn't really help communicate with the victims in an emergency like this because virtually none of the general public is going to have (and know how to use) specialized equipment that they only need in extremely rare situations. Perhaps equipment could be distributed to the volunteers, but it seems like many of the boat owners already had basic radio capabilities anyway.

There's other options as well. But I'm not sure how that would help here?
