Here's the photo I didn't know how to link before.
These are the kids, ages 14, 14, and 15. They kept the victims above water and breathing long enough for the adults (father and son, pictured) to get to the last 2 of the 3 in time.
Whether they ever get thanked by those they rescued isn't really the point--they all acted inthe best tradition of the sea.
Good on all of them.
