Mystery Armada - S. Trawler and Sub Re-furbished

Somebody has been making and releasing submarines, battleships, and other mock vessels into the four retaining ponds around the Walmart complex. They appear to be anchored in place, as they do not float about much, and pretty well-made. These are in the south pond. The trawler in the background appears to have been re-furbished after comparing it to older pictures I have, and the sub in the foreground might have been touched up also, as it looks less weathered than it should.
