Point is, CW is not used for marine emergencies anymore.

Says who? I or the victim in distress can use any mode we/they choose.
Thank you very much.

Well, knowing that the U.S. Coast Guard, and many other equivalent services
in other countries DO NOT monitor CW any more, AND CW being slower and
more cumbersome than voice, you'd have to be pretty damned stupid to USE
CW in an emergency situation!

Let's all hope and pray that he DOES use CW in an emergency.
