You must be kidding. If this ship was out in International waters - there would be US Navy ships helping rescue the victims, regardless of the ship’s flag, under the auspices of the Coast Guard.

The coast-guard also spends tons of man hours rescuing people from private yachts and fishing boats. You pay for that.
The Coast Guard deployed a vessel to the scene yesterday, from Alameda California.
I also saw a 722 footer from the Coast Guard (the Bertholf maybe?) in the area on a marine traffic site, not clear if it was there for the incident or just traveling south.
So do the boat owners.
