The choppy water problem while running the AICW’s passage across Georgia’s St. Andrew Sound results from the Waterway’s passage practically out into the briny blue, in order to clear Horseshoe Shoal, which occupies the Sound’s mid-width. Recognizing the potential for very dusty crossing here, the US Army Corps of Engineers has provided an alternate route, known as Umbrella Cut, BUT low water depths on this alternate passage can run as thin as 4 1/2 feet.
