By international law and various maritime organization like the IMO, every vessel must stop and offer assistance and rescue to any other vessel/people at sea. This goes back long before the the UN, back centuries to sailing ships and traditions of the sea.
In this incident, the Master would slow down and access the situation and call the USCG. They would likely appoint a USCG commander and work together with the Master of the Wonder and other vessels in the area. If it is deem the Wonder was not needed, the USCG Commander would release her and she goes on with her voyage. Otherwise she did just as happened, they sent a boat into the water and rescued the refugees. This same format would happen if a vessel was in danger, or burning or sinking, whatever danger is there, other vessels offer aid. If their was no USCG Commander, the Master would proceed to the best of his abilities, the vessel and the CM's to save the people.
While rescue as sea often means the CM's putting their lives on the line, that does not mean they have to be reckless or risk their lives beyond reasonable limits.
Frankly the cost of a few meals, when valued against human lives is meaningless.
Soooooo.........
A very well done to the Wonder, Master and CM's. Demonstrating the finest in Seamen ship and saving lives, and following the traditions of the seas.
