Amazing catch, Rich, particularly considering that she's back in the U. S., back in the waters where so many AGOS vessels sailed two or more decades ago. A book could be written about how this class of vessels was scattered around the world, but as long as these vessels are all still afloat, such a book would be highly premature.
