The NGA geographic database 
(http://earth-info.nga.mil/gns/html/index.html) has no Hen and Chickens 
Shoals. However, it says Hen and Chicken Rocks are at N25�59' W079�10', 
which is 5.1 NM and 304� from the end of Leg 1 that I calculated above. 
On the current sectional chart there's nothing at the NGA's coordinates, 
but 2' east is an exposed shipwreck and rocks awash. As I said earlier, 
I no longer believe that wreck is the Sapona. It's 20 miles too far north.
