Stone Horse Shoals would have been the area just to the southwest of the navigation markers for Tybee Roads. As one can see it would be no place for a vessel drawing more than 10 feet. 

Below is the information from my charting software of Dr Spence's discovery of the wreck:

This project came about while I was laid up for six weeks recovering from surgery. My IPAD got a lot of use during that time and between Netflix episodes of Mad Men I pursued my interest in studying Tybee Roads, the long stretch of navigable water that allows ships to enter the Savannah River.  I use a charting software called Simple Charts (Derek Trauger & Assoc.) .  It is really great software and it gives the location of wrecks and obstructions and as a side benefit, information about these wrecks. This is where I saw the Carrier Dove info by Dr Spence of Shipwrecks Incorporated. My interest was peaked and I then discovered the wonderful Wikipedia article about her with the contributions of several people:
